I can't get movement on the Z axis. TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. V2.1: solder bridged over the 0 Ohm resistor...all working fine on UART! Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. TMC2208 is designed for a supply voltage of 5...36V. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. You signed in with another tab or window. But I could not manage to get sensorless homing working with the MKS 2209 drivers, no matter what I tried. Already on GitHub? TMC2208-EVAL. When i add my tmc2209 to the board, do the same thing, the endstop status allways stays open So what I'm going to do is reducing the sensorless homing sensitivity to 64, that's again in the middle of 0 and 128. Can you use tmc2208 drivers with sensorless homing on an skr board or does it have to be 2209? We get this question a lot and we see some people saying that they don’t want the EZBoard because we are not using the latest TMC2209 drivers from Trinamic. If you have different problems then open a different issue providing all information needed for it to be debugged. This is not an issue since we did not cut corners like other companies on the copper and layer content of our EZBoard. skr 1.4 turbo + tmc2209 sensorless homing not cooperating when trying to adjust stall sensitivity its either crashing into the end of the axis and slipping the belt or failing homing and halting the printer. M-F 9AM to 5PM CST They both are running StealthChop V2 for extremely quiet printing. So I can both confirm that it should work, but its not working, and its not in a state where it should work either. The price of the 2208 and 2209s are about the same when purchased in full reel (2000pcs) quantities. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. After that I need to cleanup the configuration.h parameters a bit an we should be good for now. The motor supply voltage VM is a strong power supply with a high voltage. Details.

The Red boxes represent the header jumpers to be fitted for X and Y homing SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. The Orange lines are where they are wired to onboard. In addition to that we also went with the high end LPC1769 over the cheap (and limited) STM32F1XX processors due to its large memory, fast CPU speed, on-board EEPROM memory, and great support in the Marlin firmware. 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. Someone else on a BigTreeTech FB group was having issues with a CoreXY too. EZTip #2 – Removing Stress Marks from Printed Parts. Sensorless homing is simply having no physical sensors mounted on the printer. TMC2208 is an ultra-quiet two-phase stepper motor drive chip, continuous drive current 1.4A, peak current 2A, voltage range 4.75V-36V, 256 subdivision. this is very bizzare as i can read positive voltage from TMC2209 DIAG1 to Xmin signal pin? TLDR; The Creality machines do not need more than 1A per stepper driver and sensorless homing is useless (and inaccurate) on a printer that already has endstop switches. put a jumper cable directly from diag pin X and Y driver to the Xmax and Ymax endstop pin, because the XST/YST jumper pin only connect diag pin to the Xmin and Ymin! We’ll occasionally send you account related emails. Our board requires NO heatsinks even with the TMC2208 drivers because it is properly designed. P.O. This information applies to TMC drivers that are integrated to the mainboard. so that was the only change? Obviously there are many people with problems using TMC2209 with sensorless homing. Here is a video and the configs files in the description. to your account.
