When the router jogs the wrong distance, the cause can be an incorrect Scale factor(s).
Scenario
When jogging, the machine moves the wrong distance with repeatabilty, i.e. the NC file calls for a 5" cut, but the machine cuts 7" every time
Problem
There is a setup issue. The Scale Factor settings in the Techno CNC Interface need to be adjusted. Scale Factors take into account the different ratios used with different size pulleys on the various servos, to command the machine to a specific position.
Solution
Visit the Scale factors page and follow the instructions on setting up your scale factors.
If the scale factors are correct, look into measuring and correcting Backlash.
