I'm really surprised given how popular the TMC2209's are, that nobody with domain knowledge has tackled this. 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. Disabling QUICK_HOME solved the problem and it mattered not, which Axis homed first. 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. X axis seems to not register the endstop immediately and results in a split second of grinding sound. The text was updated successfully, but these errors were encountered: Here's a clearer video of the behaviour: https://photos.app.goo.gl/LBgrf79Hmc3Cm9Js7 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. 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 issue as far as I'm aware has been resolved already. 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. The combination of IMPROVE_HOMING_RELIABILITYwith the TMC2209s seems to have been what results in harsh homing. 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 MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. It's possible the issue only presents itself the first time you've enabled TMC5160 in config. 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. Steps to Reproduce. If you wanna get rid of this problem, give out the following commands: M502 --> resetting the values to the hardcoded params I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. Pastebin.com is the number one paste tool since 2002. I never said or assumed you're a company and work for profit? I guess what is happening here is - in short: privacy statement. * X, Y, and Z homing will always be done in spreadCycle mode. You want to pay attention to the bumps. We’ll occasionally send you account related emails. X axis should hit the endstop softly and register the stop immediately. Is that still grinding on a system what does not grind when the axes are homed individually? @@ -1940,10 +1940,12 @@ * Connect the stepper driver's DIAG1 pin to the X/Y endstop pin. First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. I'll update Marlin to head tonight and retry but for now I am running with quick_home disabled. question or BUG] Sensorless homing sensitivity settings. You signed in with another tab or window. 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. I see they changed the main boot-up order of things in there @teemuatlut if that means anything ? Sowerby's beaked whale is a small beaked whale that can reach up to 5.5 m in length. But what's the output of M119 after a "G28 XY"? Homing Y before X doesn't seem to matter. Configs: If you have solved the 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. For the E3D Toolchanger (beta) we have —running RepRapFirmware— we had the same problem, and finally just gave up on combined homing of XY. 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). 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. Anyway this is still happening so I would like to see this issue reopened. This issue has had no activity in the last 30 days. Right now I'm having issues making sensorless homing to work. I don't plan to switch back to sensorless until I see any sort of update. So, I just read through this, as I updated the code a couple days back, and first day it was working. No change with powering the printer on and off. The impossibility of safe automatic sensorless homing. M502 --> resetting the values to the hardcoded params Thanks for your suggestion but this isn't related. Please test the bugfix-2.0.x branch to see where it stands. Set a new target heated bed temperature and continue without waiting. Start high, for example M914 X192 Y192 and then decrease the value until it only triggers when bumping the end of the rails. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) issue, please let us know how you solved it. * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. 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'm having the same issue with TMC 2209. Set a high value for bump sensitivity and fine tune it down. Actually tried all the things here, but not helped. It failed 20 tests on 800ma and failed 0 on 200ma. Before STALGUARD can detect an axes end reliably, without grinding, it has to move SOME_WAY before. 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). Expected behavior: Axis home. The top side of the slug is covered in small wart like bumps (tubercles). Have a question about this project? I didn't find that changing the sensitivity affected this behaviour. 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). Changed to: Bugs that may have existed in 1.1.8 aren't really relevant anymore. M500 --> store it. 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. Could anyone check and report? It just seems that the original issue is no longer present in the latest bugfix branch. As long as I have the option disabled, it seems to work fine. 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. I use the waterott TMC2130s. If the head was in a position after a print such that Y endstop was encountered first there was no problem. Just yesterday I gave up all hope and reinstalled my endstops. 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). @fungustoe if QUICK_HOME were that fundamentally broken more of us would be crashing our printers all the time. Without the feature, M914 X100 Y128 seems to work really well. Subsequent quick homing is warranted to grind. If you wanna get rid of this problem, give out the following commands: (For example { 5, 7, 2 }) Then try quick homing several times. If I revert back to the 15357af commit from 5/3/19, the values are populated in the TMC drivers menu. oki, if you have the same issue we can reopen and even slam the confirmed label on it. Maybe this is related to #14464 ? This is not a big deal for me as it won't save that much time. Running M500 does not change anything. 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. [BUG] Harsh X axis sensorless homing on TMC2209. So the end position is warranted to be near the diagonal to the corner. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration.h The X axis hits the endstop abruptly, whilst the Y endstop is very soft. Each axis is backed off and re-bumped according to the [XYZ]_HOME_BUMP_MM and HOMING_BUMP_DIVISOR settings. to your account, Setup: Ender 3 Pro with SKR 1.3 and Bigtree TMC22209 in UART QuickHome begins with a diagonal move to where the endstops are. Thanks for your brilliant opinions about that. I don't currently use my delta, and my current printer has A4988 steppers, so I can't check. 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. I guess this problem is related to I was facing the same exact issue on SKR Mini E3 V2.0 Ah, that wouldn't be the issue here then, this has been an issue for over a year. Have a question about this project? If your builds are using this version, please update them to 0.7.1 and re-test. #define HOMING_FEEDRATE_XY (50 * 60). DIAG1/DIAG pin of TMCxxxx connected to the MCU I'll try to debug the IMPROVE_HOMING_RELIABILITY feature later and post updates. 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? #define HOMING_FEEDRATE_XY (20 * 60) Resetting EEPROM should be standard practise after flashing a new firmware. About Marlin what else you've tried in the meantime, and possibly this issue will be * Too low values can lead to false positives, while too high values will collide the axis without triggering. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration_adv.h. Right ? So we need to copy the file into our new marlin. I remember looking at the changes in Git from my previous code to current, and seeing a line change in 'configuration.h': SKR 1.4 Turbo + TMC2209. This feature is so sensitive that it can actually take the place of traditional endstops. Changing the source code and re-flashing the firmware does not change the contents of EEPROM. Bump sensitivity might be dependent on motor current. A few prerequisites are needed to use sensorless homing: 1. 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. Please open a new issue for related bugs. Marlin Firmware Open Source 3D Printer Driver. Expected behavior: [What you expect to happen]. Already on GitHub? 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. Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. Did I miss something in configuration process ? If you haven't, please tell us 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. 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. Sign in I'm running the SKR1.4 Turbo + TMC2209 V1.2 on the latest Marlin bugfix 2.0.x, and having the same issue. A large sea slug up to 12 cm long. The firmware will continue to try to reach and hold the temperature in the background. Even increased the sensitivity on the X until it was false triggering. 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. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. This is only apparent when homing the X and Y axis at the same time, but when homing individually the issue disappears. Even with -64 sensitivity I can't make it to work. @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? Hotend moves a mm or so and stops. This will have to be championed by someone else. Successfully merging a pull request may close this issue. I don't think this has lacked activity. The bugged release was live for about a week and affected only the SW Serial use. Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip, [BUG] (TMC2208 hybrid_threshold not updating board). There's been a number of commits, it seems, that tried to address this problem. 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. In either case, Y does not grind for me. Sorry took me longer to test as the rebase wasn't as smooth as I expected. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. Especially the 'Additional difficulties with Quick- and DELTA- Homing.' What's interesting is that, when I enable IMPROVE_HOMING_RELIABILITY, the thresholds seem to change. 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. 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. It's also possible that since TMC5160 support is still so new, not all bugs have been fixed. No other symptoms other than a harsh X home. al., today Marlin drives most of the world's 3D printers.
