@dougal1957 you can take the 5v power from an IO port and then use the negative on the fan output to allow control.

@jay_s_uk Thanks thats was the bit I was missing all now seems to be up and running.

Thanks again

Doug

@dougal1957 They don't have a stand this year

@TLAS said in anyone used Raspi compute module and Compute IO:

FYI, I’d love to see a compute module interface in the next Duet3.1 boards.

We looked at doing this when we designed Duet 3, but the cost of putting all the expected RPi I/O connectors on the Duet would have been very high, even if we did manage to find space for all of them.

Thanks Mate it was the M140 that I was missing

It is 3.3V TTL serial. And, yes, you can either figure out how to do checksums, or just turn them off (on the Duet side) and then enter pretty much any G, T, or M command you desire, and take any action on the response.

If you want the appearance of "real time" actions, you need to poll.

Has someone found a good solution?
Maybe someone with knowledge can inplement this?

ok, I split the difference and put a 2.49k pullup resistor between 3.3v and the stop. all is well now!

Thanks to everyone.
