A4988 drivers do not seem to work #26

Closed apurvakalia closed 1 year ago

apurvakalia commented 1 year ago

I created my own shield following the circuit diagrams given. However, the stepper motors just seem to jump around. I am using A4988 drivers from HiLetGo. Any suggestions? I have tried testing the drivers stand alone, but they seem to be having the same problem stand alone as well. Am I missing something? Many suggestions on the internet talk about pulling down the STEP pin. Which A4988 boards do you recommend?

I figured this out. The STEPPERONLINE motors that I am using have a different pinout for the two coils (alternate pins). Once I fixed that, things are working now
