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. Maybe this is related to #14464 ? I guess what is happening here is - in short: Anyway this is still happening so I would like to see this issue reopened. 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 don't currently use my delta, and my current printer has A4988 steppers, so I can't check. 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. Bump sensitivity might be dependent on motor current. DIAG1/DIAG pin of TMCxxxx connected to the MCU First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. What's interesting is that, when I enable IMPROVE_HOMING_RELIABILITY, the thresholds seem to change. You want to pay attention to the bumps. 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). 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? Does the behaviour change after powering the printer off and on again? i'm having the same issue with TMC 2209. Set a new target heated bed temperature and continue without waiting. Without the feature, M914 X100 Y128 seems to work really well. (no CoreXY but Prusa-Style-Printer) Right now i am using commit cbcb284 and didn't changed anything on my setup so far. 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. Using 'Home X' or 'Home Y' on the LCD screen, or G28 X and G28 … 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. The firmware will continue to try to reach and hold the temperature in the background. Lack of Activity * Lower value make the system MORE sensitive. I'd have to go back and test again, but I'm currently running a very long print. X axis should hit the endstop softly and register the stop immediately. Could anyone check and report? 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. * It is advised to set X/Y_HOME_BUMP_MM to 0. 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. Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. Hardware. Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip, [BUG] (TMC2208 hybrid_threshold not updating board). If I revert back to the 15357af commit from 5/3/19, the values are populated in the TMC drivers menu. Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. If you wanna get rid of this problem, give out the following commands: M502 --> resetting the values to the hardcoded params oki, if you have the same issue we can reopen and even slam the confirmed label on it. Have a question about this project? Please add a reply if you want to keep this issue active, otherwise it will be automatically closed within 7 days. I guess this problem is related to Have a question about this project? 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. You signed in with another tab or window. Was wondering why the last code made me increase this value so much. Do a single Z probe at a specified position. Hictop prusa clone Align multiple Z stepper motors using a bed probe by probing one position per stepper. As far as I've understood, the menu âConfiguration/Advanced settings/TMC drivers/Sensorless homingâ is intended to set Stallguard sensitivity, thus homing bump sensitivity. #define IMPROVE_HOMING_RELIABILITY was commented out. Steps to Reproduce. But I won't be testing sensorless homing on the 2209's again unless someone hints that it's actually been fixed. I'm running the SKR1.4 Turbo + TMC2209 V1.2 on the latest Marlin bugfix 2.0.x, and having the same issue. * Too low values can lead to false positives, while too high values will collide the axis without triggering. This issue has had no activity in the last 30 days. If you have solved the If you'd like me to diagnose further, just tell me what I can test, I have no idea where to start. #define HOMING_FEEDRATE_XY (50 * 60). 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. @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? I varied sensitivity from 0 to 250, but nothing changed. 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. Start high, for example M914 X192 Y192 and then decrease the value until it only triggers when bumping the end of the rails. No other symptoms other than a harsh X home. * Higher values make the system LESS sensitive. 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. StallGuard capable TMCxxxx stepper driver 2. As long as I have the option disabled, it seems to work fine. * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. I have some issues with Sensorless Homing again as well. Please open a new issue for related bugs. 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. A few prerequisites are needed to use sensorless homing: 1. * It is advised to set X/Y/Z_HOME_BUMP_MM to 0. The sensorless homing works - but it's rough as hell. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) @drewzh If the above is true, DELTAs have the same problem when the start-position is with all carriages at the same (+-SOME_WAY) height. No change with powering the printer on and off. The main culprit for me was making sure that By default probe in the current position. Already on GitHub? I don't plan to switch back to sensorless until I see any sort of update. M500 --> store it. X axis seems to not register the endstop immediately and results in a split second of grinding sound. 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. The X axis hits the endstop abruptly, whilst the Y endstop is very soft. You can try saving EEPROM with M500 and see if the LCD is properly initiated after that. The TMC2208 problem has been present ever since. * X/Y_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. 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. Successfully merging a pull request may close this issue. But I think I found the solution, at least for my case. Moreover, every change made from LCD panel are correctly taken into account, still confirmed by M122. 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. with CODEPENDENT_XY_HOMING enabled and QUICK_HOME disabled it has improved but the harsh homing on X-axis is still there. The impossibility of safe automatic sensorless homing. Most recent Marlin 2.x bugfix G28 XY. I may have something similar. This will have to be championed by someone else. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. Confirming this is an issue for me as well. About Marlin Actually tried all the things here, but not helped. After homing both axes are backed up a bit, by the same amount, to avoid grinding. 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. 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). That's the case for me. So the end position is warranted to be near the diagonal to the corner. Second day, with no changes, it started doing the "grinding" sound on X axis when homing X and Y together. 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 didn't find that changing the sensitivity affected this behaviour. So, I just read through this, as I updated the code a couple days back, and first day it was working. 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. Completely off topic (kind of), but the X axis now homes 3 times, twice as normal and then after the second home, a bigger back off and a 3rd home is performed. I use the waterott TMC2130s. The only way to really make it semi-work is to force the homing of X and Y one at a time. 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. reopened. I never said or assumed you're a company and work for profit? MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. Sign in Reliable and precise, Marlin delivers outstanding print quality while keeping you in full control of the process. If your builds are using this version, please update them to 0.7.1 and re-test. Just yesterday I gave up all hope and reinstalled my endstops. This issue has been automatically locked since there has not been any recent activity after it was closed. If the head was in a position after a print such that Y endstop was encountered first there was no problem. Even increased the sensitivity on the X until it was false triggering. The colouration of the sea slug is blotchy and variable and can be yellow, green, brown or pink. Sorry took me longer to test as the rebase wasn't as smooth as I expected. Already on GitHub? Pastebin is a website where you can store text online for a set period of time. 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. 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. SPI / UART interface of the TMCxxxx wired to MCU (stand-alone mode does not work) 3. what else you've tried in the meantime, and possibly this issue will be Marlin Firmware Open Source 3D Printer Driver. 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. Set a high value for bump sensitivity and fine tune it down. I hit this issue while setting up my new SKR 1.4 Turbo with TMC2209s using the bugfix branch at 10601a9. 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. When using SENSORLESS_HOMING with TMC2209 drivers. If I manually move to each 0 via gcode it is fine so nothing mechanical seems to be a problem. When paired with the solution proposed by @sadiwali, homing is as silent and soft as it has ever been. You signed in with another tab or window. If you haven't, please tell us 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. Successfully merging a pull request may close this issue. 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. Expected behavior: Axis home. I'll try to debug the IMPROVE_HOMING_RELIABILITY feature later and post updates. 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. question or BUG] Sensorless homing sensitivity settings. al., today Marlin drives most of the world's 3D printers. I was facing the same exact issue on SKR Mini E3 V2.0 By clicking “Sign up for GitHub”, you agree to our terms of service and If that diagonal hits the corner nearly perfect always one endstop hits first and the move stops. Thanks for your suggestion but this isn't related. I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. M502 --> resetting the values to the hardcoded params chapter. Latest bug fix Marlin 2.0. Did I miss something in configuration process ? I did not recognize it badly so I had a few hours in this. Before STALGUARD can detect an axes end reliably, without grinding, it has to move SOME_WAY before. I remember looking at the changes in Git from my previous code to current, and seeing a line change in 'configuration.h': What … 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. privacy statement. Disabling QUICK_HOME solved the problem and it mattered not, which Axis homed first. i will let it stay here then, i dont use sensorless homing so i cant confirm it. This issue is being closed due to lack of activity. 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. This issue as far as I'm aware has been resolved already. I don't think this has lacked activity. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration.h issue, please let us know how you solved it. Individually homing the axes solves this at the cost of homing speed. 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. * Higher values make the system LESS sensitive. (For example { 5, 7, 2 }) Then try quick homing several times. * * X/Y/Z_STALL_SENSITIVITY MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. Weâll occasionally send you account related emails. What is your endstop status after homing? Even with -64 sensitivity I can't make it to work. Homing Y before X doesn't seem to matter. Right ? The already hit axis can't move forward and backs up to make the second try - what works. More like request to look at that. But what's the output of M119 after a "G28 XY"? This issue is stale because it has been open 30 days with no activity. Configs: I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. Sorry in advance if you consider this as a âsupportâ question but I donât feel it is. I'll update Marlin to head tonight and retry but for now I am running with quick_home disabled. If you wanna get rid of this problem, give out the following commands: Pastebin.com is the number one paste tool since 2002. #define HOMING_FEEDRATE_XY (20 * 60) Not familiar enough with the code and electronics to say for certain. Ah, that wouldn't be the issue here then, this has been an issue for over a year. Right now I'm having issues making sensorless homing to work. 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? I do not know if this is related, but it is possible that sensorless homing issues may be caused by TMCStepper 0.7.0. privacy statement.
