Re: Auto Tool Changer Motor G0704
Hey Jeff;
If it were me I would use a small DC high torque motor and a motor driver with a brake. The motor I would look at is the RS-775 DC motor and the IMS-2 motor control with brake. This could save $$ for the stepper motor and driver. The advantage of using the geneva wheel is hat position is determined by wheel design and is mechanically repeatable. A sensor counter could determined tool position by homing and then doing geneva advance counts. Hope this makes sense.
Do you have plans for the ATC or are you winging it? I've been looking for a decent set of plans for awhile now but have only the plans from hoss to date. His plans are good but I'd rather exhause all my options before deciding which design to use. I'll be designing for a Torus Pro. I'm just about finished with a compatible Power Draw Bar and an ATC is next on the agenda.
Hope this helps.
