I have a Gravograf engraver whose controler has broken leaving only the power unit and stepper motors. I have written a program in VB net to read an HPGL file (of the design I want to engrave) and send pulses to the machine. Works a treat with Windows 98. With Windows XP the machine makes horible noises 'cos XP does not normally run in Hard Real Time. Can anybody help me to overcome my problem?
Best regards
Patch
