Wiring query for always on fan on Duet 0.6
-
I am trying to wire a Duet 0.6 for use with a delta printer with a Smart Effector.
I have wired the part cooling fan to the FAN 0 and was planning on wiring the hotend fan to Pin 40 FAN V+ and Pin 39 FAN V-.
I don't see and power at these 2 pins. Do I need to configure these pins in any way, or am I just doing something stupid?
I guess I could always wire the fan straight to the PSU if it came to it but I don't really want to do that.
Any advice would be gratefully received -
The usual place to connect always-on fans on the Duet 06 is to the Motor Loom connector. Looking at the Duet with the Ethernet connector on the right hand side, there are pins at/near the right hand end of that connector connected to +VIN, and other pins connected to ground. Sadly the reprappro documentation that showed the wiring has gone offline. I've just checked my Duet 06 with a meter, and the top right pin on that connector seems to be connected to +VIN and the pin immediately to its left seems to be connected to ground. But please check for yourself.

Thanks for the info, I will check it out.
I've just found this site which I think shows it https://emaker.io/documentation/fisher-build-instructions/electronics/ -

Many thanks........the problem has sort of resolved itself as I think I just destroyed the board.
I'm not 100% sure what happened but I must have shorted a couple of pins with the meter probe. Funny smell and the board no longer seems to be talking to anything -
Bugger! Commiserations.

Thanks for the sympathy....my own fault ,I should have been more careful.
I was rushing because that was the last hurdle to overcome before I got to try the thing out. I did exactly the same thing a few years back so I should have known better! -

I'd be happy to sell just the Duet 06 with expansion board. I could also bundle it with the PSU and/or all the cables. I'm UK based. Any reasonable offer accepted. PM me if you are interested.

...if he's interested in just the board, I may be interested in the rest with the expansion board! I've a spare 0.6 but was planning a second home printer. This could save me a fair bit in parts!

While we're on the subject, I have a Duet 06 + DueX4, modified to fix the thermistor ground noise issue that the original DueX4 had. They were running my dual-nozzle Ormerod until I replace them with a Duet 2 Maestro.

Thanks for the offer but I think I am going to pull my 0.8.5 board out my other printer, use a Duet WiFi (that I've never got around to using) in the Ormerod and then use the 0.8.5 in this delta
