I was finally able to get a good configuration and output from vCarve Desktop that works with Mach3
I still have some tweaks to do to the Postscript processor, but here was the test run. Was running at about 150 ipm, which is a bit fast, need to slow down to about 80 - 100 to crisp up the lines some, there are some delays I need to work out with the M03 and M05 commands, seems like it's pausing a lot between them.
The final output.
Also did one that was just an outline, each are about 4" x 4". This one was ran about 60 ipm, so see the start/stop points burned a little more.
