Add a fuse

[matmaxgeds]

It would be great to explore a fuse to prevent the motor drivers burning out when e.g. the chain wraps and the sprockets get stuck as suggested here: https://forums.maslowcnc.com/t/a-jam-burnt-the-motor-driver-board/3106/24

It would be simple enough for a tester to put an in-line fuse holder in one of the M+/M- wires for each motor.

If we made up some with the connectors, that would also be a good retrofit option for those who already have boards - bonus points if it is resettable

It will probably require s PCB for the male connector - it's only available as a board-mounted device

The mating connector

and pre-crimped pins for that connector

The board would make a good place for the fuse holder, though.

I was planning to add a fuse what would be the amperage needed and response time/curve?

I can't give you an exact correct answer, but my instinct says something that would blow after about 250ms at 3 amps is probably a good starting point. Feedback on if that is a good number would be awesome.
