First time trying to mill out aluminum stock and i’m having problems with the retract height. I have the retract height set in CC at 12mm but when I got to run the program the router is not retracting. Any ideas? I cut a sheet of plastic yesterday with no issues.
Please post the .c2d file.
It may be that your system is getting hung up and losing steps on retraction (assuming a Shapeoko), esp. if you’re cutting slots. Check the machine mechanically (belt tension, V-wheel adjustment, pulley set screws) per the operating checklist: http://docs.carbide3d.com/general-faq/machine-operating-checklist/

Here is the file. I’m just cutting pockets.
I just occurred to me that i’m cutting thicker material. If I don’t have 12mm of retraction will that hang up CM?
Nevermind on the thicker material. I have more than 12mm of available retraction.
Actually, I think I found the problem. Looks like the file is contaminated.
