model cooling fan and z min pins on Duet 0.65

Hi,

im trying to get my Duet 0.65 another go on my delta after it shorting on me last time i have a new one now and I remember the only extensive writing about it was on the reprap pro page, which still exists but doesnt give a complete picture of the what goes where. Motors and normal endstops are covered, but Im missing the placement of the hotend cooling fan, the model cooling fan and the z min endstop for my bed level probe.

Is there another non-omerod resource or manual for the duet 0.65? because I really dont want to wreck the board again by trying to figure out the 5V pins for the hotend cooling fan and slip and short something

Cheers

Your best bet is probably to download KiCAD [kicad-pcb.org] which is the PCB editor the duet was designed on (free and open source)

And then download the design files for the 0.65 from T3P3's GitHub here [github.com]


I used this while doing some work adding extra steppers to get more colors with a single nozzle, and it was very helpful.

I added schematics for the Duet 0.6 on the Duet wiring page. [reprap.org]
I have not done Z-probe connection schema for analog sensors, but I think David supply schematic for his own sensor.
RRP machines with IR sensors were supplied with looms, so there is no point working on that.

A generic schematic for Z-probe analog sensor may be useful.

Note that on my 'Lily' delta (built with parts of the Fisher kit), the 5V controlled fan is wired like on the schematic, but I used another diode model I had at hand. The listed diode model was tested on the Duet 0.8.5.

If you are afraid of troubles, you may better use a 12V fan with a buck converter if you are in 24V.

Hot end cooling fans are normally 12V or 24V or whatever your power supply voltage is. In that case, the Ormerod wiring diagram for the hot end cooling fan is correct. If your hot end fan really is 5V, then connect it between the 5V and Gnd pins at the end of the expansion connector. Look on the udnerside of the board to see which pins they are, all the pins are labelled.

If your bed level probe is a microswitch, connect it to the E0 endstop connector (use the two outside connections, just as for the endstop switches), and select probe type 4 in the M558 command. See [reprap.org] and the pages it links to for more configuration info.
