My printer is crazy
-
After felt 10 rolls of filament my printer starts to do strange things.
After the temperatures are reached, homing begins. The Y-axis moves normally to the limit switch and the X-axis literally creeps there (very slowly). Then the print head moves in the middle and Z-homing starts. Now the pressure starts in the middle and sometimes by a few centimeters next to it.
The printof the part is absolutely normal. The X. axis also moves at normal speed.
At the end of the print, however, the bed moves to the print head and crushes the finished print part.
Can someone help me?Firmware 2.02 (RTOS)

please post the end of a g code file where the crushing has occured

Hello,
problem found, cable from the limit switch is broken, therefore wrong switching states to the controller.
