I've been away from my machine and this forum for awhile. A lot has happened.
A few questions, I hope this is the right spot for the answers.
I have a home built CNC mill running MACH 3 and an old parralell port PC. I have no problem upgrading to MACH 4, but what all do I have to do? I'm not sure if I can change my driver box from parralel port to what, USB?
How much work to tune my machine, end stops, etc... to MACH 4 form MACH 3 info?
Is Darwin the laser cutting software or is it the name for MACH 4?
Does MACH 3 have laser cutting software?
My goal is to use my CNC machine, I will upgrade PC if needed, dont want to make new driver box for non parralel if not needed, I will buy MACH 4 if needed, I want to add to milling a laser for cutting.
Thanks.
