We have purchased a older Accu-Cut CNC Router table (11’x6’) My Dad is an old Machinist and says G-Code is G-Code, I am a hobbyist and learning. I have MasterCam and AutoCad and know this would be difficult for me to do artsy designs and lettering thru those programs. Which of these two programs between Aspire and Mach 4 are the easiest and most reliable to use? I guess i need some pros and cons of the two, I like the way Aspire looks initaly and need arguing points for this hard sell. I do not want to invest in a program and not function properly. Thanks for the help.
