CNC Router V1.0 (For Cutting Multiple Materials)

Hmm maybe I will stick with one motor and use a single large belt. I don't think it will require much modification (whilst still having the potential to run 2 motors in the future). Just need to make sure I can tension the belt well. I'm thinking of a simple idler pulley which I can slide in a slot.

You will need to make sure there are enough teeth engaged on the pulley with the belt. Also if you want to put material through the back of the machine the belt would have to be routed accordingly.

Something like below? The bottom idler pulleys on both sides sit in slots for adjusting tension.

You don't need to spend money on pulleys just to use them as tensioners.
