Craig,
No, never has a Mach plug in installed. Did not know how or where to get one until I found the parallel plug in. Never got it or installed. Got a refund awaiting UC100 as you suggested. The folder has always had just the files you showed minus that controller you said you removed from yours. The XP machine that had Mach 3 on it had a controller and did the same thing as this one. I was incorrect saying it’s a windows 10 machine it is actually windows 8.1 that I installed on for testing purposes without CNC attached. Either way, hoping it’s just the 6 min limit effecting my progress. Eagerly awythe UC100 to arrive.
