Hi David, Im just converting an interact myself (early series one).
Interesting to read re Gekos etc. Im using some compumotor S8's on
the X and y and a compumotor 610 on the z axis (2x8 amps (110V power
supply in drive) and 7 amps (DC power supply)). Theres plenty of
cooling and Im using standard BP stepper drives at the moment (P/N
026744). The machine had already been converted to Ahha control so
Im sticking to that drive and software. It should not be to long
before it starts to cut metal (just redoing the main spindle motor
bearings) and like you painting.
