Am just starting out with Mach3 on my desktop PC - for now I have the demo version only and haven't even completed my CNC machine yet... ]
My system is a little under spec, but fairly zippy in general and certainly not in bad shape for an elderly PC. The driver test works OK. It's an AMD Athlon 801MHz 384MB RAM. The crash manifests itself as a complete reset of the computer, i.e. like pressing the reset button on the front. On startup the message is 'Windows has recovered from a serious error. The crash can happen at any time, but generally it's when flicking around the screens or selecting a command, say. Left running as it would be when controlling the CNC machine, it seems fairly happy.
Also on the subject.... I had a quick play with LazyCam. I made myself a DXF in AutoCad, saved in the R112/LT2 format. Whatever I try, even something as simple as a line or a rectangle, I get the message 'No entities found' when importing into LazyCam. Any ideas?
