@droftarts and @jay_s_uk
Thanks for the answers!
The sum of the 2 suggestions solved my problem.
I think the translation of the documentation into Portuguese by Google made me misspell the D parameter of the M563 command.
I had really forgotten to activate T0.
I used RRF for a few years, since v2.03 and migrated in 2022 to klipper on all machines. Now I'm going back to RRF and I'm trying to remember everything.
Thanks to both of you!

@oliof thanks for replying.

I ended up finding the problem.

Since I've already installed a dozen Duet 2 WiFis, and I installed a Maestro over 4 years ago, I didn't remember that the Maestro has a separate binary, specific to it. My mistake!

I uploaded the correct binary, left the card with the correct firmware and it worked 100%! I already have v3.5.4 working.

Returning to AliExpress is practically impossible here in Brazil lol.

I've been buying Duets on AliExpress since 2019, luckily I haven't received a bad one yet.

Problem solved, thank you very much.

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.

@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.

@oliof thank you!
You reminded me of this detail about using the MCU temperature. I've been away from RRF for 2 or 3 years and just got back to it, and I ended up forgetting several details like this.
Thank you very much, problem solved.

@droftarts thanks for replying.
This model you mentioned, from aliexpress, theoretically doesn't need any changes to the wiring, right?

Hello everybody.
Is there any type of LCD display for the Duet Maestro that does not require any wiring changes, other than the PanelDue?

I have a mks mini 12864 v3 display (https://pt.aliexpress.com/item/1005004605578891.html), but I was confused about the change in the wires, I couldn't understand.
Is there any other that is plug and play?

@droftarts yes, I did everything right, but I tried with the wrong firmware.
I was trying to upload the firmware for the duet 2 lol.

Thanks for trying to help me!

Hello everyone!
I just received a Chinese version of the Duet Maestro and I thought it would be a good idea to do a full reset to install RRF 3.0 via Bossa (the same procedure I always do).
I performed the "fallback 2" procedure. The problem is that after Bossa completes without any errors, the board does not turn off the diagnostic LED and is no longer recognized by Windows (the Windows driver is installed). There is no point in pressing the reset button.
I tried using the 2 versions of Bossa available in the documentation.

I tried connecting the board directly to the power supply (without USB) and the diagnostic LED remains on, with the added bonus that the heat bed LED is also on.

The fallback 1 procedure does not work because the board is not recognized so that YAT can connect.

Is there anything else I can do? The board is new.
Thanks.

PS: I bought this board to replace another new board that I ended up burning out by connecting a 3dtouch incorrectly. I'm very unlucky lol.

Hello @droftarts.
It's ok. I just disabled this option because I didn't understand its purpose. When enabled, it copies the same values ​​from the hotend to the table, it seems like a bug to me.
Thank you.

Hello everybody.
Suddenly I caught the board temperatures showing the options configured for the hotend.
Is there anything I can do to fix this?
There is no point in restarting, the problem persists.
I'm still finishing setting up the printer, it's not in production yet.

EDIT: Sorry, I had activated the table's simple control mode and didn't realize what it was.

@droftarts thank you!
While you were writing, I was researching this very documentation.
Thank you very much.

I don't know yet how to mark a topic as resolved. Should I wait for the administration or can I do it myself?

Hello everyone.
Please, in RRF 3.5 is it already possible to connect a fan to the drivers that works whenever there is movement of any of the axes or extruders?
Thanks!
