Hello everyone,
I have a problem with my router. I ran it rack and pinion and the motors seemed to weak (lost steps). When I run it, on some more complex code, it starts milling, then if after some time I stop it and get it back to 0,0,0(the computer shows 0,0,0) and in reality it goes to something like -17,-77, 0. I changed the driver board, didnt help, i put in twice bigger steppers, and it acts the same. Im using turbocnc (even tried other pc).

Please help me out. I'm so tired of rebuilding it...

Thanks,
Robert
