The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks. eg if your building for a DUE you can safely delete directories HAL_TEENSY31_32, HAL_STM32F1 etc if you not using the extensible_ui delete that directory. Have a question about this project? I found that enabling CODEPENDENT_XY_HOMING and as a side effect, disabling QUICK_HOME, forces the axis to be homed in sequence rather at the same time, resulting in a perfectly quiet homing sequence. Expected behaviour: It should print a negative value; Actual behaviour: It prints a positive value; Steps to reproduce: M914 X-1 < X driver homing sensitivity set to 127 < Y driver homing sensitivity set to 4 < E0 driver homing sensitivity set to 0 Start high, for example M914 X192 Y192 and then decrease the value until it only triggers when bumping the end of the rails. al., today Marlin drives most of the world's 3D printers. About Marlin Changed to: Configs: https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration.h @boelle Yes, unfortunately so - I update to the latest bugfix branch almost every week in hopes that it's somehow magically solves, but alas... still the same :(. When using SENSORLESS_HOMING with TMC2209 drivers. Thanks for your brilliant opinions about that. @@ -1940,10 +1940,12 @@ * Connect the stepper driver's DIAG1 pin to the X/Y endstop pin. Even with -64 sensitivity I can't make it to work. MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. The forehead rises at a shallow angle and has a slight bump. (For example { 5, 7, 2 }) Then try quick homing several times. Expected behavior: Axis home. @bthome, @CSHoffie, can you guys check with an oscilloscope or multimeter that the DIAG pin of your TMC2209 on the griding axis is not asserted when the caret hits the limit? The top side of the slug is covered in small wart like bumps (tubercles). I am also running an SKR 1.3 with genuine 5160 Watterott drivers in SPI/sensorless homing mode on an Ender-3 with the bugfix-2.0.x commit (940ff8e) from yesterday and the a613bca commit from 5/10/19. M914 X55 stops without reaching the end of the rail, whereas M914 X54 hits and grinds at the end of the rail for ~4 seconds. Now onto the latest GCode as of Marlin 2.0.5 G0-G1: Linear Move First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. No change with powering the printer on and off. By clicking “Sign up for GitHub”, you agree to our terms of service and Hi. Sign in Was wondering why the last code made me increase this value so much. Note that Y axis homes softly as expected and X axis takes too long to register, resulting in a rough home. It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. Most 3D printer electronics include a little bit of storage (512K, 3K, or more) called EEPROM (Electrically Erasable Programmable Read-Only Memory) that persists when the power is off. I haven't had a chance to do enough troubleshooting but I wonder if increasing the "recheck distance" (the distance the bed/extruder moves away from the extruder then towards it to check the end stop the second time) would help. If X homes before Y, then X grinds, and vice versa. X axis should hit the endstop softly and register the stop immediately. Especially the 'Additional difficulties with Quick- and DELTA- Homing.' Is that still grinding on a system what does not grind when the axes are homed individually? (no CoreXY but Prusa-Style-Printer) Right now i am using commit cbcb284 and didn't changed anything on my setup so far. Already on GitHub? The colouration of the sea slug is blotchy and variable and can be yellow, green, brown or pink. i will let it stay here then, i dont use sensorless homing so i cant confirm it. DIAG1/DIAG pin of TMCxxxx connected to the MCU Marlin 2.0.5.3; Square Wave Stepping (Beta Feature) ... *Bump sensitivity set to 100 for X and Y this will need to be configured according to your machine as they all behave differently, these values can be changed on the touch screen and are found under machine settings-parameters, or by the terminal using the M914 command. Align multiple Z stepper motors using a bed probe by probing one position per stepper. Michel. * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. Please open a new issue for related bugs. So my guess is that with true endstops, the faster speed is okay, however with Sensorless, it causes either noise that blocks the bump, or less power at the faster speed, so the bump doesn't register? question or BUG] Sensorless homing sensitivity settings. A quick test for the theory would be to configure HOMING_BUMP_MM asymmetric for x and y by + SENSORLESS_BACKOFF_MM of that axis. For those of you, like me, who are into 3D printing, here is a quick, and VERY helpful set of marlin gcodes for your Marlin firmware. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Have a question about this project? A large sea slug up to 12 cm long. Pastebin is a website where you can store text online for a set period of time. @fungustoe if QUICK_HOME were that fundamentally broken more of us would be crashing our printers all the time. If that diagonal hits the corner nearly perfect always one endstop hits first and the move stops. With my latest compile I re-enabled quick homing to see if I could narrow it down using different configs, but no luck so far. * Lower value make the system MORE sensitive. I do not know if this is related, but it is possible that sensorless homing issues may be caused by TMCStepper 0.7.0.

After homing both axes are backed up a bit, by the same amount, to avoid grinding. No other symptoms other than a harsh X home. The X axis hits the endstop abruptly, whilst the Y endstop is very soft. chapter. #define HOMING_FEEDRATE_XY (50 * 60). The humback whale is relatively robust rorqual and can reach up to 16 m in length. The bugged release was live for about a week and affected only the SW Serial use. * X/Y_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. well there are many updates applied every day/week and you will need to watch the commits to figure out if any update might have fixed the problem, marlin is not a company and we all work for free. For the E3D Toolchanger (beta) we have —running RepRapFirmware— we had the same problem, and finally just gave up on combined homing of XY. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) I don't think this has lacked activity. This will have to be championed by someone else. Using 'Home X' or 'Home Y' on the LCD screen, or G28 X and G28 … For the other axis, where the endstop was not already triggered a first move is initialized, what will grind because the possible way to move was smaller then SOME_WAY. With the feature enabled, same settings make homing too sensitive. to your account, Bonjour à tous, I'm really surprised given how popular the TMC2209's are, that nobody with domain knowledge has tackled this. Set a high value for bump sensitivity and fine tune it down. If you wanna get rid of this problem, give out the following commands: Without the feature, M914 X100 Y128 seems to work really well. * It is advised to set X/Y/Z_HOME_BUMP_MM to 0. A way to fix could be, to back up both axes (that with the not hit endstop could de enough (if easy detectable)) at least SOME_WAY after the diagonal move and before the homing of the individual axes. If I manually move to each 0 via gcode it is fine so nothing mechanical seems to be a problem. * Lower value make the system MORE sensitive. G28 and X grinds (Y does not), G28 X = No grind. Homing individually seems to stop the behaviour, i.e I can issue constant G28 X commands and not have a single instance of the grinding behaviour. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks. By clicking “Sign up for GitHub”, you agree to our terms of service and I just hope someone be cleverer than myself can pin this down. I remember looking at the changes in Git from my previous code to current, and seeing a line change in 'configuration.h': privacy statement. Hardware. You signed in with another tab or window. I have this sneaky feeling that there is something nasty lurking in the endstops.cpp code that is disabling the X endstop, when QUICK_HOME is in effect, and whilst I took a look through the code it quickly exceeded my capabilities in C++ and my will to live. This issue is being closed due to lack of activity. Hotend moves a mm or so and stops. But what's the output of M119 after a "G28 XY"? Sorry took me longer to test as the rebase wasn't as smooth as I expected. Individually homing the axes solves this at the cost of homing speed. So we need to copy the file into our new marlin. If you have solved the Thanks for your suggestion but this isn't related. * X, Y, and Z homing will always be done in spreadCycle mode. @drewzh If your builds are using this version, please update them to 0.7.1 and re-test. Just testing again today and IMPROVE_HOMING_RELIABILITY doesn't seem to make much difference (except for slowing the bump process down slightly - assuming to make it more accurate). If this is connected to the TMC2208 problem then that problem was caused by changes to Marlin in this commit .. https://github.com/MarlinFirmware/Marlin/tree/15357af67ceb74b14606eba9fbb75d20914f8909. I'm trying to set-up a printer SKRv1.3-based with sensorless homing feature, using TMC5160 on X and Y axis. I hit this issue while setting up my new SKR 1.4 Turbo with TMC2209s using the bugfix branch at 10601a9. One more thing that I realized is that with Z, you don’t really want bump homing so Marlin documentation is spot-on about that. But X and Y values are always set to 0 after initilisation (Power on or Reset) while M122 command shows default values defined in Marlin. Since the board equipped with EEPROM, Marlin has stored the sensitivity data (in my case 0) and whenever I was uploading a new software, used the EEPROM stored value. More like request to look at that. Marlin's help article about the TMC drivers: ... And you can bump the voltage up to as high as 36V according to ultimachine, and you actually just sort of get a free lunch here: the extra voltage will increase the strength and performance of the motors even if the drive current stays fixed. Actually tried all the things here, but not helped. I did not recognize it badly so I had a few hours in this. Even then, it still happens randomly. Right now I'm having issues making sensorless homing to work. #18563. You can try saving EEPROM with M500 and see if the LCD is properly initiated after that. But I won't be testing sensorless homing on the 2209's again unless someone hints that it's actually been fixed. Using auto home, X homes using sensorless homing, Y homes using sensorless homing, as it proceeds to the bed center to home Z it grinds and never makes it to center. If the head was in a position after a print such that Y endstop was encountered first there was no problem. Ender 3 Pro SKR 1.4 Turbo w/ TMC2209 Bump sensitivity might be dependent on motor current. This is reported by not only myself, but another member of the "BIQU SKR Owners Group" over on Facebook: https://www.facebook.com/groups/247860246136776/permalink/331864144403052/?comment_id=332138477708952&reply_comment_id=333026657620134&comment_tracking=%7B%22tn%22%3A%22R%22%7D, https://www.facebook.com/groups/247860246136776/permalink/331864144403052/?comment_id=332138477708952&reply_comment_id=333041497618650&comment_tracking=%7B%22tn%22%3A%22R%22%7D. * Higher values make the system LESS sensitive. I'll try to debug the IMPROVE_HOMING_RELIABILITY feature later and post updates. Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. [Stupid (?) It's possible the issue only presents itself the first time you've enabled TMC5160 in config. I varied sensitivity from 0 to 250, but nothing changed. Please add a reply if you want to keep this issue active, otherwise it will be automatically closed within 7 days. to your account, Setup: Ender 3 Pro with SKR 1.3 and Bigtree TMC22209 in UART Moreover, every change made from LCD panel are correctly taken into account, still confirmed by M122. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. This issue is stale because it has been open 30 days with no activity. I did not recognize it badly so I had a few hours in this. Disabling QUICK_HOME solved the problem and it mattered not, which Axis homed first. I seem to have solved the issue by increasing the HOMING_BUMP_MM and enabling SENSORLESS_BACKOFF_MM as follows: I've lowered these values, and they seem to be working fine. I guess what is happening here is - in short: This issue as far as I'm aware has been resolved already. What … I'm running the SKR1.4 Turbo + TMC2209 V1.2 on the latest Marlin bugfix 2.0.x, and having the same issue. M502 --> resetting the values to the hardcoded params So, I just read through this, as I updated the code a couple days back, and first day it was working. What's interesting is that, when I enable IMPROVE_HOMING_RELIABILITY, the thresholds seem to change. Configs: Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip. We’ll occasionally send you account related emails. I don't currently use my delta, and my current printer has A4988 steppers, so I can't check. We’ll occasionally send you account related emails. When I disabled quick home, there were still instances of the behaviour at other times (sorry I can't be more specific), so the issue isn't solved by homing in sequence, but it is masked in the usual pre-print G28. Subsequent quick homing is warranted to grind. But X and Y values are always set to 0 after initilisation (Power on or Reset) while M122 command shows default values defined in Marlin. The sensorless homing works - but it's rough as hell. In this video, I show you how to configure Marlin 2.0 for the SKR 1.3 mainboard with TMC2209 stepper drivers and sensorless homing. I was facing the same exact issue on SKR Mini E3 V2.0 I use the waterott TMC2130s. Separately they were fine. If you'd like me to diagnose further, just tell me what I can test, I have no idea where to start. Lack of Activity Pastebin.com is the number one paste tool since 2002. The lower jaw has a single pair of teeth (exposed only in adult males). I've personally given up on them for now - I've already burnt many hours testing new dev builds over the course of a few months and I just don't have the time anymore. The humpback whale Megaptera novaeangliae is a baleen whale and can be recognised as such by the plates of baleen (rather than teeth) suspended from the upper jaw and the two blowholes on the upper body. I never said or assumed you're a company and work for profit? I don't plan to switch back to sensorless until I see any sort of update. Homing Y before X doesn't seem to matter. QuickHome begins with a diagonal move to where the endstops are. The TMC2208 problem has been present ever since. So the end position is warranted to be near the diagonal to the corner. I get quite a decent amount of false positives and setting the Bump Sensitivity to a higher value doesn't affect anything but i can't really explain why the issue occurs. The combination of IMPROVE_HOMING_RELIABILITYwith the TMC2209s seems to have been what results in harsh homing. Anyway this is still happening so I would like to see this issue reopened. If the above is true, DELTAs have the same problem when the start-position is with all carriages at the same (+-SOME_WAY) height. As soon as I home X and Y together (for e.g, with G28 XY), I get the grinding issue (about 90% of the time). It's also possible that since TMC5160 support is still so new, not all bugs have been fixed. privacy statement. Please test the bugfix-2.0.x branch to see where it stands. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration_adv.h. Resetting EEPROM should be standard practise after flashing a new firmware. The text was updated successfully, but these errors were encountered: The boot process should initiate the LCD variables accordingly but it's possible it isn't working correctly with TMC5160 (or others). https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration.h, https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration_adv.h, https://photos.app.goo.gl/LBgrf79Hmc3Cm9Js7, The impossibility of safe automatic sensorless homing, Issue a full auto home of X and Y axis with either G28 or G28 X Y. Right ? You want to pay attention to the bumps. Marlin uses the EEPROM to store the printer settings and loads them up the next time the machine powers up. Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip, [BUG] (TMC2208 hybrid_threshold not updating board). It has a distinct beak and the mouthline is curved down at rear. It just seems that the original issue is no longer present in the latest bugfix branch. I have some issues with Sensorless Homing again as well. X axis seems to not register the endstop immediately and results in a split second of grinding sound. I also noticed that homing a single axis, also makes the opposite axis 'twitch' after being homed - not sure if this is expected or a previously seen behaviour? This issue has been automatically locked since there has not been any recent activity after it was closed. Latest bug fix Marlin 2.0. By default probe in the current position. Y axis still homes twice as expected - is that normal? Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. oki, if you have the same issue we can reopen and even slam the confirmed label on it. It failed 20 tests on 800ma and failed 0 on 200ma. MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. I guess this problem is related to Auto-home one or more axes, moving them towards their endstops until triggered. I see they changed the main boot-up order of things in there @teemuatlut if that means anything ? With bump sensitivity at 35 for TMC2130 stepper drivers I ran 100 tests with motor current at 800ma and 200ma without changing the bump sensitivity. The main culprit for me was making sure that I'll update Marlin to head tonight and retry but for now I am running with quick_home disabled. Sorry in advance if you consider this as a “support” question but I don’t feel it is. If I revert back to the 15357af commit from 5/3/19, the values are populated in the TMC drivers menu. Second day, with no changes, it started doing the "grinding" sound on X axis when homing X and Y together. In either case, Y does not grind for me. Actual behavior: Axis don't move, X/Y endstops are triggered. As long as I have the option disabled, it seems to work fine. Each axis is backed off and re-bumped according to the [XYZ]_HOME_BUMP_MM and HOMING_BUMP_DIVISOR settings. SKR 1.4 Turbo + TMC2209. Most recent Marlin 2.x bugfix G28 XY. The impossibility of safe automatic sensorless homing. It’s also a good idea to add these two lines [home bump] right after the sensitivity settings to keep the printer from bumping into the axis ends too often. I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. Well I just replaced the speed back to 20 * 60, and not only did it fix the problem, but I was also able to significantly drop the TMC Bump Sensitivity value (X & Y from 65 back to 25). * Higher values make the system LESS sensitive. There's been a number of commits, it seems, that tried to address this problem. Do a single Z probe at a specified position. In order to do that simply minimize Notepad++ (but leave the windows open) Use your Windows File Explorer and navigate to \STM32-master\Marlin_ER20\Marlin\src\pins\stm32f1\ inside the eryone firmware folder. The only way to really make it semi-work is to force the homing of X and Y one at a time. It has a ring of eight or nine upright feathery gills close to the posterior end, which are quickly retracted when a disturbance is sensed. This should be fixed with PR #14008 thanks to @marcio-ao.

In the end, sensorless homing in working fine (only tested on X only yet) with values defined in config_adv.h, but it’s very confusing behavior. Before STALGUARD can detect an axes end reliably, without grinding, it has to move SOME_WAY before. #define IMPROVE_HOMING_RELIABILITY was commented out. I'd have to go back and test again, but I'm currently running a very long print. Interesting - I just checked my platformio libdeps and TMCStepper is at 0.7.1...I wonder if the update to bugfix was just a red herring and it's actually this library that's fixed it? Things seem to be much smoother now - though I haven't checked whether IMPROVE_HOMING_RELIABILITY actually changed the behaviour, but after this current print is finished I'll re-enable and give it another check. Disabling QUICK_HOME is definitely a solution... but this problem has been around for a while and not necessarily associated with TMC and sensorless homing. Hictop prusa clone I may have something similar. It also seems like the threshold becomes impossible to get right. Sensorless homing works fine and running M122 , returns the correct values from EEPROM for all three of these commits. As far as I've understood, the menu “Configuration/Advanced settings/TMC drivers/Sensorless homing” is intended to set Stallguard sensitivity, thus homing bump sensitivity. i'm having the same issue with TMC 2209. reopened. You signed in with another tab or window. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Setting TMC bump sensitivity (M914) via terminal only adjust TMC bump sensitivity for the X stepper driver but not for the Y stepper driver (at least for me). M500 --> store it. The firmware will continue to try to reach and hold the temperature in the background. If you wanna get rid of this problem, give out the following commands: M502 --> resetting the values to the hardcoded params The already hit axis can't move forward and backs up to make the second try - what works. StallGuard capable TMCxxxx stepper driver 2. what else you've tried in the meantime, and possibly this issue will be * * X/Y/Z_STALL_SENSITIVITY Running M500 does not change anything. Confirming this is an issue for me as well. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. Even increased the sensitivity on the X until it was false triggering. When paired with the solution proposed by @sadiwali, homing is as silent and soft as it has ever been. This issue has had no activity in the last 30 days. The motherboard is an eryone specific development and is NOT included in the standard marlin. IMAGES and other media featured on this page are each governed by their own terms and conditions and they may or may not be available for reuse. Expected behavior: [What you expect to happen]. Now homing the individual axes begins. Does the behaviour change after powering the printer off and on again? Hello, my name is Daniel, welcome to the CrossLink channel. * Too low values can lead to false positives, while too high values will collide the axis without triggering. Reliable and precise, Marlin delivers outstanding print quality while keeping you in full control of the process. However for X and Y, bump homing makes things a lot more stable so I have bump enabled for X/Y and disabled for Z. Tweaking the sensitivity is actually quite easy. [BUG] Harsh X axis sensorless homing on TMC2209. Not familiar enough with the code and electronics to say for certain. Right ? A few prerequisites are needed to use sensorless homing: 1. I remember thinking, cool, faster XY homing. In short - the root cause seems to be IMPROVE_HOMING_RELIABILITY. Marlin Firmware Open Source 3D Printer Driver. A few things got in the way :) I've just re-flashed with latest bugfix-2.0.x today and checked that IMPROVE_HOMING_RELIABILITY is switched off. This is not a big deal for me as it won't save that much time. Sowerby's beaked whale is a small beaked whale that can reach up to 5.5 m in length. See M422 for Z-Stepper automatic alignment parameter selection. No update from me. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. with CODEPENDENT_XY_HOMING enabled and QUICK_HOME disabled it has improved but the harsh homing on X-axis is still there. issue, please let us know how you solved it. #define HOMING_FEEDRATE_XY (20 * 60) Could anyone check and report? @TheNitek the end stops are reporting fine and homing is otherwise running as expected. Set a new target heated bed temperature and continue without waiting. BIGTREETECH SKR V1.4 Turbo 32bit Controller Panel Board for 3D Printer Compatible With12864LCD/ TFT24 Support 8825/TMC2208/Tmc2130 (with 5TMC2209): This is the heart of this upgrade.The stock board is an 8-bit board and this one is 32-bit with a bunch of better features like sensorless homing and UART. If you haven't, please tell us This is only apparent when homing the X and Y axis at the same time, but when homing individually the issue disappears. The text was updated successfully, but these errors were encountered: Here's a clearer video of the behaviour: https://photos.app.goo.gl/LBgrf79Hmc3Cm9Js7 Did I miss something in configuration process ? Maybe this is related to #14464 ? Just yesterday I gave up all hope and reinstalled my endstops. * Too low values can lead to false positives, while too high values will collide the axis without triggering. Remove stale label / comment or this will be closed in 5 days. As far as I've understood, the menu “Configuration/Advanced settings/TMC drivers/Sensorless homing” is intended to set Stallguard sensitivity, thus homing bump sensitivity. But I think I found the solution, at least for my case. For sensorless homing, the default sensitivity setting should be ok for most printers, but of course you can play with it if it is too sensitive or not sensitive enough. , [ BUG ] harsh X home ] ( TMC2208 hybrid_threshold not updating board ) when I enable IMPROVE_HOMING_RELIABILITY the.
