Random positions x axe

piet_deen

Hello,

When I do a home command for the x axe, the x axe travels home smoothly and stops on the x_max_stop. X position in the host gets black, reading 290.
I performed the following sequence: X home from the host (no G code) and than G1 X 145. This sequence was repeated several times. The result was random x positions of the printer head along the x axe.

I played with the x_steps_mm variable but no luck.
My calculated setting is x_steps_mm 88.9.

Can someone tel me what I have to configure to have a repeatable movement?

Thanks in advance for your suggestions

The homing stops when endstop signals high. So first question would be is that always at the same position or not. If not you have cross talk on your x endstop and that stops it at different positions.

An other reason might be loosing steps due to too high speed/acceleration.
