All, I have been working with my CNC for 2 years now and have had no issues what so ever with Aspire creating toolpaths and scaling them correctly. Recently my CPU failed and I had to replace the computer. I had a day old backup of Mach3 so I loaded it and placed the license and XML file in the directory for Mach 3. The issue is now my scaling is all screwed up. When I create a toolpath the output from Mach 3 is much smaller. Ive already checked the scale to job in Aspire and nothing changed in Mach still a smaller job. I have already checked the motor driver scale pulse per inch setting. I even changed it from 400 to 81 and the result is the same a really small job from a large toolpath file. Ive looked at a bunch of posts and followed all the resolution suggestions to no avail. What am I missing, HELP!!!
