Just wanted to share my experience building my CNCrouterparts pro machine with mach4. Plenty of help with a ready to go mach3 xml but it's been a little difficult to find those who've taken the plunge with Mach4 on this machine. I have to say that is a bit surprising as it’s been out a while now. I've used that program for about 2 years on my mini mill and have had no issues so why spend the extra $$. It was a slow start as I had to do a bit of detective work to translate some items over but now it’s all falling into place. Once I get all systems working I plan to share for others who are interested in a step by step. There’s got to be some folks taking or have taken the same journey.
