looks like i am just super lucky. so i remembered that on the 5th driver slot right side of the female pin strip was bent at a 45 degree out of the box. i bent it back thinking it would be fine. this happens to coincide with the motor that is reversing. so something is up w/ the board. back this one goes! on to the THIRD board. golly gee i am lucky.
Or just recompile the firmware to skip that driver and use #6… the physical damage like that is S&H not the board production process. Tjat cod happen to anything…
ok so third board was the charm lol
back up and running. jst-xh for all end stops as well as resistors. did a few tests today and all is well.
