RE: [CAD_CAM_EDM_DRO] 2 stepper in parallele usage for more power

Hi Tim,

I do not have anything ready jet, I’m in the design phase.
I need to have the middle of the table empty, so I was thinking of the two separate screw (yes like gantry, yet a new word) set-up to accomplish this.

Dose the Mach2 slave mode mean that if you have an 4 axis breakout board you can use the 4: th axis as the slave with its own drive, motor and screw?

“If you have one step/dir pin to drive two drives”
Do the Gecko 320 servo drive have TTL level inputs? If it dose would the parallel port have the power required (not to far away!)?

Sorry a bout my English!
Many thanks ese
