Hi,
TL;DR, The XY coordinates are ok when homing and when moving via console (klipper), but when performing Z_TILT_ADJUST they are not corresponding and way of.
I’m in the process of finishing my Ratrig VCore 3.1 500x500 printer. The XYZ axis work fine when homing and manually setting the toolhead position via Klipper. But when I perform the Z_TILT_ADJUST, the actual X and Y position are not corresponding to the configured z-tilt probe points, they are not even close. The Klipper toolhead interface does say that it is located at the correct positions, though.
I tried using the G90 and G91 gcodes before starting the Z_TILT_ADJUST, no effect. I tried switching the X and Y motors, but then it moves the wrong way.
I tried the following z-tilt probe point configurations:
X-axis only
100, 100
200, 100
300, 100
When starting from X0 Y0, the toolhead moves near the corresponding coordinates, with a difference of a few cm. So after the Z_TILT_ADJUST, it is located on X250-ish in stead of X300. Klipper says it is X300. When I then change the direction to X0 in Klipper, it bumps into the side causing the belt to slip, even though there is an endstop. I’ll guess the endstop only functions for homing. Anyway, the actual position was clearly off from the position that it thought it was at.
When starting from X250 Y250 (normally after homing), it moves relative from that point.
Y-axis only, 40mm increment
100, 100
100, 140
100, 180
With configured increments of 40mm it is making steps of around 35mm along the vertical path (Y), but it also changes the X axis a bit.
Y-axis only, 100mm increment
100, 100
100, 200
100, 300
Now with 100mm increments, it moves only 20mm and also a little on the X axis. Then after the first levelling attempt, it wants to move to negative Y and bumps onto the frame.
It really makes no sense to me. I could provide a video if that helps. Anyone any suggestions?
Thanks.
