Hi, Just wondering if anyone is having a similar issue to mine. I recently got the E3D tool changer printer and started setting up for the first time yesterday. I have noticed that homeY is keep failing even after adjusting the sensitivity value on M915. I am not new to duet board, I have used it for number of 3D printers that I customised. Trying to understand as per why the homing is not working as it should, I have noticed that the grub screw fixed onto the end of the Linear motion are not aligned (>1mm). So when the left side of the Y axis is hitting the edge the right side is not! (see image) So the sensorless homing at Y-axis works when the speed of the motion is increased so much that the y-axis frame is literally slamming! onto the grub screw. However, this cause a change in the Y-axis coordinate every time when I want to change the tool. I also tried using individual stepper driver for sensorless homing but still not functioning. Did anyone have similar issue?
