Stepper motor not turning under load

Hi, @moofrog
Welcome to the forum.

Can you please post a copy of your code, the information above will show you how to put it in a scrolling window.

Can we please have a circuit diagram?
An image of a hand drawn schematic will be fine, include ALL power supplies, component names and pin labels.

Do you have a DMM?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:
