I am posting for the first time here, so please bear with me. I have been searching this and other forums for this particular problem, and rather than start a new post on the same topic, I thought it is more appropriate to add it in here.
My only worry is that no-one will see it.
Anyway, I've just finished setting up a 3040 Router (the Chinese version) with Mach3 and although at the start, things didn't look too good, but I'm now at the stage where the X and Y motors are running sweetly; except for the Z axis.
It will only run in one direction regardless of which key is pressed.
I have swapped the pin allocation from either X or Y to Z and the same effect happens, only a different key does the move: this suggests that the signals from the PC are not getting through.
I've looked at the Config pages dozens of times, but nothing is leaping out that is obviously wrong. I've allocated different keys to the Z axis, with the same single direction.
Has anyone had the same problem with this?
