I'm not sure if this is correct forum for help with 3D printer problems. The original controller board in my SainSmart Coreception 3D printer was bad and the extruder kept on jamming. I replaced the controller board and hotend. I thought that I fixed the problems until something went wrong while printing. I think that I set VREF too low or something is binding on the X and Y carriages.

How can I fix the problems? How should I lube the linear bearings?
I had a similar problem on my printer. On mine it was, mainly, the Y axis. I figured that the TMC driver gets too hot and I didn't have a cooling fan on the drivers. I put a fan blowing directly on the drivers and now I have no more skips on any of the axies. I had raised the amps on the Y axis to 1000 and I also have put some cooling fins on the motors. These ones.
