Well got it working then shut it all down and stepped away. Kept PC on, came back later to run some tramming/squaring using Mach 3, no issues. Figured i'd start the swap to 4 now that the spindle issue was resolved. NOPE, same thing, except now it wont even kick using the settings from before, i feel like i'm going crazy. Set the spindle speed (pulley) to min 0/18005 max, set to 300Hz(tried 1000/even 25 for giggles) no dice. Messed with it for another 1.5 hrs to see if I could replicate getting it to work like earlier but no go. Just shutdown the computer and i'll try again tomorrow. Once configured, are the settings saved? Shouldnt my spindle rpm setting show under the spindle once i click the enable button?
