Not my code, definitely- this happens when I'm using the shuttlepro to jog, mostly. I'll set the zero points and jog off them then go enter a g1x0y0 in the MDI interface- and the thing doesn't move. So I enter it again, stil no movement. So I check to see what's wrong, and the 'Normal Condfition' flasher is on. I enter a g90 before the g1x0y0 and it works. I want to know why it's not holding a normal condition, because very soon after I enter that g90 I have to enter it again.
