Okay, it's been a while, and this project was put to a side but now I'm back at it. I bought a cheap USB motion controller from eBay
https://rover.ebay.com/rover/0/0/0?m...2F163110531211
I plugged it in to my laptop for testing, connected some relays and they work okay, however I don't get any rpm readout! The index light comes on in the diagnostic screen but no matter what I do, the sTrue stays at 0 🤔
Is the controller supposed to tell mach3 what the rpm is?
Did I go wrong by going cheap?
Help!
