Title: Wire encoders to SS or Gecko ?
Post by: Pythagoras on November 09, 2010, 01:56:25 AM

I'm not sure what all the pros and cons of wiring encoders to a Smooth stepper VS wiring back to the Gecko drive.

Does wiring back to the SS mean the system is closed loop?
I can see that if I wired back to the SS this would mean that I couldnt use the multiplier optionon the GeckoDrive. Is this correct?

Does any one know the pros and cons of wiring back to the SS?

You need to wire the encoders to the Geckos or you will not have closed loop to the drive, connecting the encoder to the SS will not give you closed loop.
The encoder inputs on the SS are I presume really meant for MPG input although I do have my spindle encoder going back there, for two reasons. One is the Index pulse is used for  the spindle feedback to Mach and the second is  in the hope that one day the spindle may have some sort of synchronising with the Z although I dont think it will as room is tight on the SS now.
