@fcwilt said in Help with sensorless in duet 3 mini 5+:

I didn't think it would make a difference and it didn't.
So why are you using H4 instead of H1?

I just haven't changed it yet.

@phaedrux Yes thanks. I had already done that.

Hi @jumpedwithbothfeet , thanks for replying.

It's just that the M308 command is not enough for it to appear on the main tab. I already have the sensor set up and working.
For it to appear on the main tab, it must be connected to a heater, just like the hotend and table sensors.

See the "Sensor borda" in the second tab (extras). I would like this to appear in the tools tab.

As I understand it, I need to create a virtual heater and connect this sensor to this heater, so that it appears in the tools tab.

Hello. I have a fysect big dipper board (similar to duet3 mini5+) and I'm having trouble getting the nozzle heater to work.
I used the RRF Config Tool website to generate the config.g, but I must have gotten some information wrong.
I've already reviewed each gcode in the configuration but I still can't find where I went wrong. The thermistor is reading the temperature correctly, the hotend fan is working according to the hotend temperature correctly. The problem is that the heater doesn't heat up, it stays OFF all the time, even though I set the temperature via DWC.
Could someone tell me where I went wrong?

The heater cartridge is connected to the "V_FUSED+" and "OUT2-" ports in the diagram below. I've also tried configuring it on the "OUT1-" port without touching the wiring, but the result was the same.

I'd appreciate it if anyone could shed some light on this.
Thank you.

@dc42 thanks for replying.
I removed the sd card and the connector still gets very hot, and very fast. I can't even keep your finger touching the USB connector.

@droftarts
I read the content of the link you sent, thank you.
Yes, it gets a little hot under the main processor, but you can keep your finger on the board. However, it is not possible to touch the USB and SD card connectors, as they get very hot in just a few seconds!

It really seems like I joined the list of people who managed to burn a Duet, lol.
I have already ordered a new board.
Thank you very much for your reply.

Hello everyone.
I connected a 3dtouch probe (trianglabs) to a Chinese Duet Maestro board by mistake. Now the power supply via the USB cable is getting so hot that the USB connector is burning my fingers. Connecting it to a 24V power supply makes one of the LEDs light up, but the board does not connect to the local network.
Did I permanently burn the board or is there something I can still do?
Thanks to anyone who can help.
(sorry for the Google translate, I'm in Brazil)

Greetings from Brazil!

I have a thermistor measuring the temperature of the edge of my table (350x350x8mm). This thermistor is not connected to any heater and serves to delay the start of prints until the edge of the table is warm enough (temperature close to the center of the table).

I would like the temperature to appear in the main DWC tools tab. It only appears in the EXTRAS tab. It is possible?
Maybe simulating a virtual heater, so this thermistor is hooked up to a heater and can pop up? I don't know how to do this yet. Can anyone help?

Duet2 + duex5, RRF 3.4.2, Voron 2.4, silicone pad 750W 220V.
Sorry for the english by google translator.
Thanks.

@droftarts An excellent contribution, thank you very much for this!

@droftarts
Thank you very much! I hadn't seen this documentation yet, it seems to be new, I don't remember having seen it.

Hello everybody.
I read in the documentation that it is possible to add extra drivers to duet2 without having to use a duex. If I misunderstood this, it was possibly my translation error.

Stepper driver expansion
Up to 7 additional stepper drivers, of which up to 5 can be TMC2660
External stepper driver support
Up to 7 external stepper drivers when not using DueX expansion board. Signal levels are 3.3V. A 4-channel expansion breakout board is available to level shift them to 5V.

To buy an original duex and bring it to Brazil, we pay more than 3x the value of the plate, due to the exchange rate, import fees from Brazilian customs and the extremely high freight. Unfortunately, the only viable option was the Chinese versions of aliexpress, which suddenly disappeared from the site due to lack of chips (makebase reply in chat).

I would like to have a triple Z on my hypercube and to do that I would need an extra driver on my duet2 wifi. I use bltouch connected to the expansion connector, I don't know if it would be possible to add an extra driver like that.
Could someone who understands how to do this share?
Thank you very much.

@o_lampe Ok I'll do it. Thanks!
