Hi-
After reading the thread here:
https://www.electro-tech-online.com/threads/function-modules.21839/
and checking holding torque...(by feeling with my hand)
There is not enough.
I am using stepper model #155432
Detent (holding) torque: 220 g-cm how does this translate to how much weight I need to move- application is to move 2 pounds on the shaft.

And driver ULN2003A
https://www.chipcatalog.com/Datasheet/BF9F0B98CCAD47B5A194F50D062D8A3F.htm
It is using 12V (supply) and controlled by PIC16C711.
I'm pretty sure I have the correct sequence in the code but the torque feels really low for 12V.
It also chatters.
I'm totally new at this - any advice is appreciated.
Thanks-
Kappa
