A few years ago, I walked into my shop.
I started my pc for my CNC machine, and for some strange reason, Mach 4 would not come on.
I looked for a solution online, and I found out that windows 10 had made an update that stopped Mach 4 from coming on.
ArtSoft did at the time post the solution on the forum, and I updated my version of Mach 4 to a new version to solve the problem.

For this reason it is very important that ArtSoft not block the UC 100 drivers from working.

This same problem is very likely to occur again at any time.
