Ok here's the deal i'm trying to help a guy that owns a CandCNC Bladerunner, DTHCII, thats all i know it as because it doesn't say much on the darn things box.
They computer full out died a death of age, so a new computer has been put in its place, fresh install of Windows 7 Pro 32bit, nothing else other then SheetCam which they are used to using.
I went to the CandCNC website and got their update to Mach3 from their downloads section and they all in one installer for the older machines that gives you everything for Mach3. I can jog the machine, i can zero it, that all works fine. However i can't seem to get it to load any gcode correctly. When i load a .tap file from Sheetcam i see a flicker of the toolpath in the toolpath area in Mach3 and then its BLANK. If i mouse over the toolpath window and zoom in and out or rotate the toolpath flickers into view briefly with each mouse click or movement but then quickly goes blank again. It will run and try to cut, i disabled the torch and had it just run the toolpath, the axis's move like they should and i bet if i put a marker in place of the torch it would be tracing out the toolpath on cardboard just fine, an old trick i learned when setting up my CNC router to test everything, but no matter what i do i can't get the toolpath display to work for them. Even when its running the gcode the toolpath display is blank and just white.
Any ideas before i start taking a 10lb sledge to things??
