Just installed a new set of rail gears on the x-drive on one of our PRT Alphas.
These were direct replacments for the previous gears.
Also updated to Shopbot 3.514, and updated the control box firmware after having missed several updates.
Now having major headaches cutting circles with both imported files and the CC command, they are coming out slightly ovalled and not really smooth.
We've cleaned and lubed everything, checked for square, level and plumb.
This is one of the very last PRT's to be shipped and was upgraded to Alpha shortly after purchase, and doesn't have the hi-def motors.
Any suggestions?
