On our QSP-2, the Y axis belts start to vibrate during the process so we need to open the doors to stop this because of the humming sound. What can creates this knowing that all the movements and placement are spot on?

Got it. Servo tuning is new to us, so we'll try it. When you propose to swap the Y axis amps, do you refer to the driver that controls the Y motors? Thanks,

Seems to be fighting to hold its position. 1. Check for anything worn out...possibly idler bearing/pulley and/or the belt. 2. Maybe it could use servo tuning...this may help but usually servo tuning is not that critical. 3. Clean the scale and the

The amp is mounted on the back side and is black. 4 total mounted for x and y axis.....swap the 2 that are y axis amps. If you have never servo tuned before on a quad machine you not going to be able to do it. There is way to many things that you nee

It'll just transfer the load to your compressor, and who knows how efficient your venturi pump (which can also be noisy) will be (IOW, how much load it puts on your compressor is anyone's guess)? I'd just replace or rebuild the vacuum pump, person
