i am a beginner with mach3, i have just bought a CNC machine
when i move my x axis or any other axis with 1 in mach3 my CNC machine moves with 0.3 centimetr
i want to define a scale in mach3
i want to multiply the current scale by 3
i hope if somone can help me

To multiply your current movement distances by a factor of 3 then go to  Config / Motor Tuning and multiply the ‘Steps per’ by 3. Do this for each axis clicking ‘Save Axis Settings’ after each change.

As an alternative you could go to the Settings page and use the Axis Calibration feature to set the correct steps per unit for each axis.

Tweakie.

thank you very much the first solution  worked
