Hi, We recently switch out our old PRS style rails (closet door look?) with some Linear Guides. It runs like a dream, or at least it seemed to until it started erroring out constantly. After about 10 hrs of running. Well As I looked at the motors I noticed 2 of them (1 X, and the Y) had little to NO teeth! I checked the tension on all the motors and noticed that the person doing the work had put the motors on so tight all the springs were stretched out. I couldn't push the motor off the track. I always thought the spring tension should be tight enough to still be able to push off the track with a little bit of pressure. We got the 2 new gears in overnight (Thanks Shopbot!) but now he puts them back on with that same tension if not tighter! Is this going to strip out the teeth running it with that much force on the pinion to the rack?
