Hi Julie,

RE: driving the long axis with 2 motors. You don't have to with R&P!

All I did was to make a shaft with a pinion on both ends and a drive pulley inboard of one of them. Then simply mount the motor in line with the pulley and you are driving both sides of the gantry with 1 motor, no crabbing, simples.

If you want to get fancy you can use a zero backlash pinion on one end but I didn't think it needed on a router.
