X Axis Dir active low
Posted: Sun Jul 08, 2018 6:43 am
I'm just getting started with UCCNC and came from Mach 3. After finally getting the motors running I couldn't get the X axis to go the correct direction. No matter what I did with ports and pins it wouldn't change. My setup is a single stepper for each axis but I decided to try slaving A to X and also ported the same pins to them. It finally reversed the direction of X. I then disabled A as slave and now X acts normal. Not sure if this is a bug or not but I wasnt able to change the direction of X until I slaved it with A using the same ports and pins as X.
