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?

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 read head if you can get to it. 4. You could always swap y axis amps.

good luck, Bob

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,

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 need to know. It takes me an hour just to remember all the hidden keys to open up the screens correctly.

Swaping Y amps from a correctly working QSP-2 to this QSP-2 did not change anything: belts still vibrate.

However, belts are in good shape, tension has been adjusted and bearings are turning free without play. Will try to swap Y motors from a correctly working machine unless a better idea arise.

It sounds like someone needs to check the servo tuning.
