I have a brand new licensed copy of Mach3. I have calibrated my steps per MM with Mach3’s auto calibration. I removed any Mach3 files anywhere on my PC. I downloaded Mach3 and installed it and UC100 drivers. To test I created a 5x5x5 square profile cut. It consistently cuts 4x4x4. I also have used Aspire and it does the same thing. I’m pulling what’s left of my hair out. The common denominator seems to be Mach3. I would appreciate any suggestions.
Can you share the gcode file and bit size?
Did you adjust anything is the settings tab to adjust nominal vs measured distance? The axis calibration part…You set a distance and then measure that and enter what the actual distance is for each axis.
Will a 2,5x2,5x2,5 => 2x2x2?
If so its a step/mm issue
If it isnt its a offset value
I thought Aspire did the same thing, but it seems to work.
Yes I can share the gcode. The bit 1/16" 12 x 24 1/4" thick.
I have just shared the project. I created a rectangle and in Shape put 5.0 in height and 5.0 in width.
