Re: [CAD_CAM_EDM_DRO] bridgeport stepper motor specs - help

Geckos are a bit undersized for Bridgeport motors. To get decent feed
rates run them at full current (no resistor) and the highest supply
voltage possible. Also run the motors in half winding mode:

2 connected to phase A+
8 connected to phase A-
1 connected to phase B+
6 connected to phase B-
The other terminals are left unconnected.

With Geckos set to full current and with a 75V supply I get reliable
2.4m/min (96IPM) rapids and plenty of torque.
