Hello. It's my first time using the CNC12 Software and I'm having serious problem. Every job I load seems to be running measured in Feet instead of inches. How do I fix this? Thanks.

Hello and welcome to the Forum.
Sounds like an odd problem.
Can you please post a Fresh report from CNC12. The report can be created in the F8 Utility menu.
Also a look at the Gcode with this issue would be great.
Is all other motion outside of a job correct?
If you Command a G1 move in MDI does the Machine more the correct amount?

Is the report really a fresh one?
It looks like all the motor settings are still stock.
Have you set up the Wizards Configuration menu?

The only motor config I've done is axis inversion and max feed rate. Is there something else I should be doing? This is my first time so please forgive my ignornace

The last reply about motor settings prompted me to google a bit and a youtube video pointed me in the direction of tuning motor travel/steps per revolution via the config menu with a password lock of 137. It turns out the default minimum value of 1600 allowable in the cnc12 wizard which I did try changing before I posted here was about 8 times too high. Dialed in the motor rated settings and fined tuned with testing and now I'm good to go.
