Motors running too fast? - Croccy22 - 04-13-2017 06:46 AM
Can anyone confirm that this code is fully working?
I have set it up with a NEMA17 (200 step) motor and an A4988 driver.
The code seems to run but when I push the button the motor starts spinning with the large gear rotating at 1 revolution every 4 seconds. This seems to fast comparing it to video of other trackers I have seen?
Is this correct?
I have set the parameters in the code but it's still the same.
Any help greatly appreciated.

Just in case anyone else has this issue it looks like it's because I haven't enabled micro stepping on the A4988. To do this the MS1, MS2 and MS3 pins need to be high. Will test when I get home but I am sure this is the solution.
