I saw you were going to check for slip on the belt drive to your Z axis, how did that turn out? also, how much backlash is there in the screw? another thing... the belt is a timing belt, right? and there is no possibility of slipping there?
one last thing... if you suspect the amp on Z might be problematic, have you swapped it with another axis to see if the problem follows the amp or stays on Z? Just some thoughts I had while reading this topic, hopefully you find your culprit soon. Jim ------------------------------------------------------------------------------ Come build with us!
