I changed the standart bed system to an CORE XY and upgraded firmware properly. It worked fine so far with printing. It has now been a while since i used this printer (1month) and i was trying to print something. But the printbed hardley move. The Stepper motor sound weird and shake pretty strong. I checked the Voltage for the Stepper each at 0.56 Volt. For the driver.
The mechanic works fine when i move it via hand. Anyone have a suggestion? Can it be the Repetierhost which i downloaded? I thougth i just have to set the settings in the firmware for CORE xy or do i have to set it in repetierhost aswell?
The Config file is changed in unccomend corexy and change the step rate of the first to values to 100
Something worked, and then quit. That usually means something broke. Inspect the Z motor cable and connectors. If it looks OK, swap the Z motor connections with one of the other motors and see if it works. If the problem stays at the Z motor output on the board, you probably have a bad driver. If the problem follows the Z motor, you probably have a bad z motor cable or connector. If neither work, you probably have a bad z motor cable that destroyed the Z motor driver.
Thanks. As you suggested i was looking at the cables. At Second motor of the printing bed i was using simple connectors and one of them was lose. Thanks for you help !.
The stupid cable was behinde the printer so i couldnt .see it furthermore i forgot that i used connectors.
