SmoothStepper USB / ESS / G540 / PMDX-126 WTF? About to give up
« on: April 28, 2014, 08:43:52 PM »
Hello All
I am trying to integrate a Smooth Stepper / G540 / PMDX-126. I understand the G540 is its own breakout board but I just want to use it as a motor driver. I spoke with PMDX and they said it was possible to get this to work by (I think) hooking up the G540 to PMDX-126 (J19). Smooth Stepper Port1 to PMDX Port 1 and Smooth Stepper Port 2 to PMDX Port 2. I am not sure what I am doing wrong but I just cannot get it to work. I am pretty sure I am missing some things in ports and pins and maybe some other things in Parallel Port / Smooth Stepper settings. Any advice / detailed instructions / Application Notes would be greatly appreciated. I have wasted well over 40 hours trying to figure this out when I am pretty sure there is a simple solution. I am about to give up and call it a day, which I really don’t want to do. Please advise
