Hey,
It’s finally running!
Swapped out the uno for a mega, found another small quirk after being able to now properly debug, and it went well for hundreds of cycles as I was just casually having it chugging along.
Btw. is that accelstepper node now working ? I’m still looking for something that provides me with such feature 
Thanks a lot for all the support so far, hope I can contribute back in the time coming 
Dan
