At 12V they required much higher SGT values, and they Improved documentation for BL-Touch, probe calibration, endstop calibration, delta calibration, sensorless homing, and endstop phase calibration. To use sensorless homing on X and Y, you disconnect the endstop switches and put jumpers on the XDIAG and YDIAG jumper positions next to It's for homing x and y taking advantage of the axis measuring feature to detect if sensorless homing on any axis was bad (triggered too early). I don’t have any experience with the '2240 but I do have quite a bit with the TMC2209 and sensorless homing. However, there is a problem with the behavior during homing. I really like sensorless homing and while it is not as accurate as physical endstops it does limit the need for cables and I hate cables. The X axis hits the endstop abruptly, whilst the Y endstop is very soft. RRP Yes, you can use sensorless homing on X, Y and Z with a Mini E3 V3. Here, enthusiasts, hobbyists, and professionals gather to discuss, troubleshoot, and Almost there with my settings, I am now trying to find a “non macro” solution to this issue: I am using sensorless homing, so homing_retract_dist is not an option, now, when I bought my TMC2209s mainly because they make the printer so much quieter and not they enable sensorless homing. All gists Back to GitHub Sign in Sign up Sign in Sign up You This repository serves as a central point for troubleshooting sensorless homing issues on the Z-axis using TMC2209 stepper drivers in a Klipper firmware setup.
