This is a 5 x 10 foot Thermwood router, so the motors are TEN FEET apart. All the mechanicals are complete, this is only a controller retrofit. The motors are pretty small (650 Oz-In continuous servos) so it really needs both motors. It worked for years with the Thermwood controller. I think the motors are on little gearboxes with rack and pinion drive, and the shaft may well be impossible to set up without completely redesigning the machine.
