Step Angle on Motors

[Damius]

Hello, I’ve ran into issues with using two different step angle motors for the gantry (0.9 and 1.8). So when I try to move the gantry, it moves in a diagonal direction. Is there a simple solution to this?

Any help would be appreciated

p.s I haven’t updated my blog since I’ve started but I’ve 95% completed this machine lol

3 options, the software option, the electronics option and the hardware option.

1. Go to the firmware. There you can configure the steps per mm of each axis (though I am at this point not sure if it is possible for the gantry).

2. Under each stepper motor driver there is a header with jumpers. Here you can configure microstepping. Make the 1.8 motor the default, and configure the 0.9 motor so it has 2x less steps (if the 1.8 motor has 1/4 steps, make the 0.9 motor 1/2 steps). This can also be combined with the 1st option.

3. Make the 0.9 motor a 1.8 motor. This is the easiest, though I understand that you are looking for an alternative.

Changing the jumpers worked! Thanks
