Problem: Homin issue on CoreXY

Kenabi31 commented 1 month ago

SOLVED: im using a hbot system, i had to choose the midtbot kinematics, NOT the corexy kinematics.

What happened?

Hitting the Hard Limit of X Axis, the X Axis motor stops rotating as it should but the motor for the Y Axis still rotates; and the same for the Hard Limit of Y Axis, the X Axis motor keps rotating; making proper homing impossible.

What was the solution, in case someone else encounters the issue?

im using h-not kinematics, I thought I had to pick corexy but it was midtbot kinematics
