Occasionally, while printing, my y axis will slip and the layer will, from that point forward, be shifted, ruining the print.

What might be the causes of an axis slipping? I have tried cooling the motor which seemed to have been getting warm, and the belts are not too tight.

This does not happen with every print, and seems to be an intermittent problem.

My printer is a MendelMax RepRap, and the y axis is my moving bed.

Make sure your controller board/electronics board etc is as cool as possible - if not the axis may jump - that's what happened with me - after adding additional fans over the Ramps/Adruino - I did not have the problem again (so far)
