I'm having problems with LPKF 91s milling machine. The start position for the milling changes a few mm in the y-direction. This happens every time after a drill bit is changed or when the tool is routed to home position/drill bit change position.
I checked the skrewbar on which the rotor moves and it seems that there is a missing platic part from the other side of the skrewbar. Could this be the reason why the y-direction shifts on start?
Any help would be appriciated
