Art,
I have tried all versions of GSIM on my system, a MachMotion with Galil controller. Mach4 goes into failure immediately upon trying to startup under the diagnostics tab. The screen goes into frosted mode and a continuous wait circle appears until I click on the toolpath window and get the error window box where I can close t. I have tried debugging it with Steve Murphree, but we have no luck so far. Steve suggested that I contact you to try and get a debug build to try. Is it possible for you to send me one?
Thanks,
Kenny Crouch
