What's the best way to implement dual X motors?
« on: July 14, 2007, 06:53:15 PM »
My application is a CNC router with two X rack & pinion drives. I can identify two solutions. Software and hardware. I am looking for the advantages/disadvantages of slaving another axis with the X to accomplish this (in Mach3). I am using a PMDX-131. I would rather slave two geckos off of the same channel on the PMDX and save the axis in Mach and PMDX for a second Z axis. Does anyone know if the PMDX buffer can drive two geckos in parallel? I would like to hear some pros and cons to both solutions.

I think it can be done (I have not done it my self but I know of others that have done it)... Also if you don't need to have the homing to straighten the X axis I think you are fine with ganging the outputs...

Thanks
