@crowem I use the Noctua 4010 fan with Duet 3 Mini 5+ and like dc42 said, i connect to the 4 pin PWM port as follows:

GND not used VOUT+ Red Wire out.tach Yellow Wire out- Red Wire

this gives the full functionality showing the RPM as well.

@Phaedrux I have a silicone sock on the nozzle, it is a hemera, with the volcano and an e3d high precision heater cartridge. I have two cooling fans wich are just 5010 blowers, which i tired turning down for the tuning but it did not do anything. I ordered a new heater cartridge, so that may fix this, otherwise it is probably a faulty toolboard which i will need to get replaced

@dc42 I returned it, and got a new one, works with no issue

@SimonK ah OK, I've just read your first post in this thread. Yes, reversing the VIN power does blow the driver, unless the supply current is limited to a very low value.

@rogerpodacter Which "spare heater connector negative" are you using? On Duet and (pretty much all) printer control boards fan/heater outputs switch the negative line line (to provide pwm control), so there is a good chance that this connection is not connected directly to the negative supply. I would move that connection so that it is directly connected to the power supply and see if you still have the problem.

@Jered said in Duet 3 Expansion Board 3HC Motors Not Working Properly... Again!:

After saving the config, it asks if I want to read the config again or restart the controller.

I think when it asks if you want to read the config again or reboot if you choose to read it again it basically does a M98 P"config.g" to re-execute the config.g file as a macro. Usually that's enough, but as you say, perhaps it has to do with the high number of expansion boards you have.

@apak i have not tried this but i dont understand the function. are you thinking this will allow my fan to stop at zero %?

@norder The BLTouch was blinking red, which I just learned was the error state.

I power cycled the printer, and now it is working as intended 🙂

Thanks for your reply!

RRF2 and RRF3 are quite different, config files need to be updated accordingly.

I think that seems reasonable.

@alankilian I sure appreciate your help on this. Thanks

@oliof thank

@deckingman
Thank you very much for your help. 🌷 🌷 🌷 🌷

@Phaedrux The bigger watt power supply seems to have fixed the chirping humming noise, and the red led for the bed heater is solid and no longer flashing!

You might find some other example conversions by searching the forum.

@tandar
In case anybody else reads this thread
In the process of upgrading my trinus to a more modern control board i have evaluated the options for adapting the bed and chosen what in my opinion is the most simple and straight forward
The mod is reversible but does require some wiring and a thermistor.

Hope this helps
Kodama heated bed mod

While the board i have is slightly newer than the OP's they are compatible with each other
and the Panowin Kodama & Bardo boards so the wiring / pin outs etc should be identical

@dc42 It is actually in the doc, I don't know why I missed it. Thanks.

Ok, so I just recalled that my plan was not to do a 'sensorless home', but to travel backwards for the full length of the axis, and assume the axis is at zero because of stalling. Just a small FYI.
