My gantry type router has been doing pretty well over the last 2 years but now for some strange reason it's misbehaving. This is what happens, when setting up for a sign I do a practice run first just to make sure and then rout the sign. Sometimes it will cut a perfect sign on the practice run then on a decent piece of hardwood one of the motors makes a strange noise and it will cut one letter on top of the other as if loosing steps.
Just for the record the setup is as original, nothing has been changed.
Any suggestions would be gratefully received.
