Hi,

the X-Alis "Step Pin#" in the "Motor Outputs" tab gets set to some random pin number everytime.

I have to manually set it back to 2 everytime and after some time, it gets set back to some other random pin number.

Any idea what causes this and how can I prevent it from happening again?

Thanks in advance.

Try changing it to the correct number then saving and exiting  restarting Mach. Other thing to look for is make sure you dont have any other output set for that pin, not sure if that would do it but....

I think you need to download the newest Rev of Mach3 and that should fix the problem

Thanks
Brian
