I started building this machine last year, i have all the machined parts done. I just ordered the 8020 for the frame. Has anyone out there built on? Chris from data ct recomends flachcut for the control software. I was thinking of using maxch 3 instead of flashcut. Has anyone out there made this modifaction? If so how did it go? Any problemss? Do the rest of the componets work with mach 3? Thank you for your help.
