I have one more question abt the motor movement.
When I do homing the gantry, sometimes x, y axis go to inverse direction continuously after touching the opto endstops until collision of column.
And when I print to check the motor movement(not really printing, I’m still setting the printer), the cartridge holder doesn’t go to near build bed. It just moves little from home position, and do printing motion.
Can you give me any advice?
The questions are very minor for you, but I really need your help.
