You can run as many stepper drivers as you like off the same signals assuming there is enough electrical drive to run all the optos. I have an Accucut 48" router that was wired that way from the factory (different control.) When I converted it to LCNC I didn't change it for simplicity. Works fine. It has a very slight rack that some day I will correct when I add a second home switch and run separate step/dir cable to the 2nd motor controller. ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
