Mach3 is powerful software but it is not without its problems. Here is a case where the settings of the mach3 panel didn’t want to cooperate with the physical settings of the machine. Occasionally there could be some unforeseen problems that we have never seen before like the Mach3 calibration that doesn’t match the physical dimensions of the screw. When this happens we will have to calibrate the axes correctly but manually to eliminate conversion or hardware errors.

In order to calibrate each axe separately and correctly for a screw that is not defined or has wear, follow these simple tasks in Mach3:

Step 1: Launch Mach3 under the desired profile and click the settings Tab (alt6)

Step 2: Click the "set steps per unit button" at the bottom of the screen

Step 3: This will show a window with "pick axis to calibrate" written on it

Step 4: Click the axe you wish to calibrate then okay

Step 5: Then enter the distance that you would like to move

Step 6: The machine will move to this distance

Step 7: The window appears where you can enter the actual physical distance that the cnc has moved. Make sure you are exact and use a long distance because errors are propagated and will affect how your Badog CNC works after this point.

After this last step repeat these steps for all 4 axis and then save the settings. The machine will be perfectly calibrated to the physical settings that you have programmed in. Usually we do not have to do this with a machine but I have included it because it is not without explanation that I have found a case where the config file was not matched to the machine settings
