HIYA Stirling you are correct I remember the offer since you mentioned it, BUT there was not anything here to run it on at that time .
DID you get the serial interface working to be able to talk to your THC from Mach3 ?? To be able to change the preset voltage on the fly ?? That is what is needed to do feedrate slowdowns for arcs and keep the cut quality correct. Would be a handy item to have for the hobbiest that has a bare bones plasma cutter. An auto version that did Preset arc voltage changes on the fly based on Feedrate would be nice. I did some mods to the CandCNC that did it. You Help me with the programming to interface mach3 back through the CandCNC . I had to jump OUT to a VB script then bring it back into Mach3 and then back to the THC to reset the arc preset value to match a feedrate change.
THat was a WHILE back though.
Here I cut with an older HT1000 (Hypertherm) and it does NOT have the magic plug either.
