marlin bump sensitivity

DIAG1/DIAG pin of TMCxxxx connected to the MCU I hit this issue while setting up my new SKR 1.4 Turbo with TMC2209s using the bugfix branch at 10601a9. If the above is true, DELTAs have the same problem when the start-position is with all carriages at the same (+-SOME_WAY) height. I'll update Marlin to head tonight and retry but for now I am running with quick_home disabled. * Too low values can lead to false positives, while too high values will collide the axis without triggering. 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.

Pastebin is a website where you can store text online for a set period of time. * Lower value make the system MORE sensitive. 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. 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. The X axis hits the endstop abruptly, whilst the Y endstop is very soft. Now homing the individual axes begins. I'd have to go back and test again, but I'm currently running a very long print. privacy statement. Running M500 does not change anything. This issue is stale because it has been open 30 days with no activity. Homing Y before X doesn't seem to matter. @fungustoe if QUICK_HOME were that fundamentally broken more of us would be crashing our printers all the time. oki, if you have the same issue we can reopen and even slam the confirmed label on it. You signed in with another tab or window. Already on GitHub? The colouration of the sea slug is blotchy and variable and can be yellow, green, brown or pink. Please add a reply if you want to keep this issue active, otherwise it will be automatically closed within 7 days. Right ? * 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.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. Weâll occasionally send you account related emails. SKR 1.4 Turbo + TMC2209. This issue as far as I'm aware has been resolved already. A large sea slug up to 12 cm long. 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. What … Expected behavior: Axis home. Moreover, every change made from LCD panel are correctly taken into account, still confirmed by M122. Configs: Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip. The impossibility of safe automatic sensorless homing. X axis should hit the endstop softly and register the stop immediately. You can try saving EEPROM with M500 and see if the LCD is properly initiated after that. Was wondering why the last code made me increase this value so much. 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 will let it stay here then, i dont use sensorless homing so i cant confirm it. It's also possible that since TMC5160 support is still so new, not all bugs have been fixed. Align multiple Z stepper motors using a bed probe by probing one position per stepper. 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? Anyway this is still happening so I would like to see this issue reopened. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Using 'Home X' or 'Home Y' on the LCD screen, or G28 X and G28 … If your builds are using this version, please update them to 0.7.1 and re-test. What is your endstop status after homing? Is that still grinding on a system what does not grind when the axes are homed individually? Hello, my name is Daniel, welcome to the CrossLink channel. 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. If you wanna get rid of this problem, give out the following commands: M502 --> resetting the values to the hardcoded params to your account, Bonjour Ã tous, * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. QuickHome begins with a diagonal move to where the endstops are. I see they changed the main boot-up order of things in there @teemuatlut if that means anything ? Before STALGUARD can detect an axes end reliably, without grinding, it has to move SOME_WAY before. Steps to Reproduce. This is only apparent when homing the X and Y axis at the same time, but when homing individually the issue disappears. The firmware will continue to try to reach and hold the temperature in the background. Y axis still homes twice as expected - is that normal? Have a question about this project? 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. 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). I'm trying to set-up a printer SKRv1.3-based with sensorless homing feature, using TMC5160 on X and Y axis. [BUG] Harsh X axis sensorless homing on TMC2209. with CODEPENDENT_XY_HOMING enabled and QUICK_HOME disabled it has improved but the harsh homing on X-axis is still there. This issue has been automatically locked since there has not been any recent activity after it was closed. I don't plan to switch back to sensorless until I see any sort of update. This issue has had no activity in the last 30 days. I'm running the SKR1.4 Turbo + TMC2209 V1.2 on the latest Marlin bugfix 2.0.x, and having the same issue. The lower jaw has a single pair of teeth (exposed only in adult males). I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. A few prerequisites are needed to use sensorless homing: 1. With the feature enabled, same settings make homing too sensitive. Does the behaviour change after powering the printer off and on again? MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. If that diagonal hits the corner nearly perfect always one endstop hits first and the move stops. More like request to look at that. The bugged release was live for about a week and affected only the SW Serial use. I guess this problem is related to Could anyone check and report? Hi. I do not know if this is related, but it is possible that sensorless homing issues may be caused by TMCStepper 0.7.0. Ender 3 Pro SKR 1.4 Turbo w/ TMC2209 Thanks for your brilliant opinions 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. Sorry in advance if you consider this as a âsupportâ question but I donât feel it is. * Higher values make the system LESS sensitive. Even with -64 sensitivity I can't make it to work. Separately they were fine. * It is advised to set X/Y/Z_HOME_BUMP_MM to 0. Pastebin.com is the number one paste tool since 2002. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration_adv.h. Bump sensitivity might be dependent on motor current. 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 use the waterott TMC2130s. Sensorless homing works fine and running M122 , returns the correct values from EEPROM for all three of these commits. This should be fixed with PR #14008 thanks to @marcio-ao. For the E3D Toolchanger (beta) we have —running RepRapFirmware— we had the same problem, and finally just gave up on combined homing of XY. Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. I'm really surprised given how popular the TMC2209's are, that nobody with domain knowledge has tackled this. If you wanna get rid of this problem, give out the following commands: Have a question about this project? The sensorless homing works - but it's rough as hell. If the head was in a position after a print such that Y endstop was encountered first there was no problem. 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. Confirming this is an issue for me as well. In short - the root cause seems to be IMPROVE_HOMING_RELIABILITY. Actually tried all the things here, but not helped. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. Ah, that wouldn't be the issue here then, this has been an issue for over a year. Lack of Activity 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 The motherboard is an eryone specific development and is NOT included in the standard marlin. @TheNitek the end stops are reporting fine and homing is otherwise running as expected. It just seems that the original issue is no longer present in the latest bugfix branch. Configs: i'm having the same issue with TMC 2209. #define HOMING_FEEDRATE_XY (50 * 60). The only way to really make it semi-work is to force the homing of X and Y one at a time. In the end, sensorless homing in working fine (only tested on X only yet) with values defined in config_adv.h, but itâs very confusing behavior. So the end position is warranted to be near the diagonal to the corner. Please open a new issue for related bugs. 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.

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. The combination of IMPROVE_HOMING_RELIABILITYwith the TMC2209s seems to have been what results in harsh homing. Sorry took me longer to test as the rebase wasn't as smooth as I expected. This is not a big deal for me as it won't save that much time. reopened. The forehead rises at a shallow angle and has a slight bump. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) By clicking “Sign up for GitHub”, you agree to our terms of service and You want to pay attention to the bumps. In either case, Y does not grind for me. 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? If I manually move to each 0 via gcode it is fine so nothing mechanical seems to be a problem. Sowerby's beaked whale is a small beaked whale that can reach up to 5.5 m in length. 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. (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 possible the issue only presents itself the first time you've enabled TMC5160 in config. Each axis is backed off and re-bumped according to the [XYZ]_HOME_BUMP_MM and HOMING_BUMP_DIVISOR settings. Disabling QUICK_HOME solved the problem and it mattered not, which Axis homed first. Michel. 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. 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. Second day, with no changes, it started doing the "grinding" sound on X axis when homing X and Y together. I remember looking at the changes in Git from my previous code to current, and seeing a line change in 'configuration.h': 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. 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). You signed in with another tab or window. Especially the 'Additional difficulties with Quick- and DELTA- Homing.' Even then, it still happens randomly. I just hope someone be cleverer than myself can pin this down. 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). 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 never said or assumed you're a company and work for profit? I'll try to debug the IMPROVE_HOMING_RELIABILITY feature later and post updates. 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. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. #define IMPROVE_HOMING_RELIABILITY was commented out. Auto-home one or more axes, moving them towards their endstops until triggered. Actual behavior: Axis don't move, X/Y endstops are triggered. The text was updated successfully, but these errors were encountered: Here's a clearer video of the behaviour: https://photos.app.goo.gl/LBgrf79Hmc3Cm9Js7 al., today Marlin drives most of the world's 3D printers. Marlin Firmware Open Source 3D Printer Driver. 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 What's interesting is that, when I enable IMPROVE_HOMING_RELIABILITY, the thresholds seem to change. M500 --> store it. Individually homing the axes solves this at the cost of homing speed. 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. See M422 for Z-Stepper automatic alignment parameter selection. to your account, Setup: Ender 3 Pro with SKR 1.3 and Bigtree TMC22209 in UART G28 and X grinds (Y does not), G28 X = No grind. Sign in 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). No other symptoms other than a harsh X home. * * X/Y/Z_STALL_SENSITIVITY Latest bug fix Marlin 2.0. Did I miss something in configuration process ? 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. I don't currently use my delta, and my current printer has A4988 steppers, so I can't check. Set a high value for bump sensitivity and fine tune it down. 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. I varied sensitivity from 0 to 250, but nothing changed. Maybe this is related to #14464 ? But I won't be testing sensorless homing on the 2209's again unless someone hints that it's actually been fixed. The already hit axis can't move forward and backs up to make the second try - what works. As long as I have the option disabled, it seems to work fine. Thanks for your suggestion but this isn't related. @drewzh About Marlin @@ -1940,10 +1940,12 @@ * Connect the stepper driver's DIAG1 pin to the X/Y endstop pin. Resetting EEPROM should be standard practise after flashing a new firmware. * X, Y, and Z homing will always be done in spreadCycle mode. 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. I don't think this has lacked activity. If you haven't, please tell us 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?
