hi,

I have built a large format printer 405x450x600.
Was trying to get away with using 2x Z Axis Stepper Motors, but I really need 3x Motors, in a Triangle.

Can I please some advice on driving 3x Stepper motor in parallel from the Duet/Duex Boards.
When driving 2x Motors the Chips on the Board get quite warm/almost to warm to touch.
I have added heat sinks and cools fans to the board but I don't want to damage the boards.

I know that someone else must have done this previously as well.

Questions :
Did you use a stepper motor driver amplifier ?

What is Recommended ?
