I'm a bit confused by the reaction here. Sure PP works (well not for me yet since mine arrived not working), but there is nothing wrong with Mach 3 if properly configured on a decent quality computer. I have four machines running Mach 3 and ESS offboard motion controllers. I also have one running the same with an older USB-SS, and I can run upto atleast a couple million lines of code on any of them. They have their issues, but as I have been reading so does PathPilot.
Is the reaction I am seeing just brand loyalty or something?
