Hello. I have a WD41093 series Duet 3 MB 6HC and just inserted the included SD card into it for the first time. Heard a click/pop sound, doubted myself if I inserted the card properly but after double checking it was correct. The board does not see the SD card I suppose since I get the Your Duet rejected the HTTP request: page not found Check that the SD card is mounted and has the correct files in its /www folder and sending M997 S0 through console gives me Error: M997: Firmware binary "Duet3Firmware_MB6HC.bin" not found when I just put the file there from my PC (so card is OK).

Through the top "notch" of the SD socket it seems like one pin what maybe is supposed to contact with one of the pins of the SD is out of place (as in bent weirdly) also the whole cover of the socket lifts when I insert the card and the two solder points look like were never soldered

If guided I can try to take the cover off but I don't want to loose the warranty.

Please help, thank you.

Thank you very much. I promise I spent like 3 hours googling. Maybe that post should be somewhere in the docs?

I have precisely the board from the faulty series.

Thanks again, this is resolved.

Hello. I scanned the forum for similar issues and started my debugging process by we wiring everything once I red that crimps maybe the issue but then it occurred to me that I can simply check each axis on the working drives and the end result is that nothing works on drivers 0, 1 and 5, everything work on 2, 3, 4.

When X (drive 0) report's an error I pulled it's plug from the board (power off) and connected it to drive 3 (which was supposed to be my U), moved U everything works. Tried with all axis - the only variable was the drive, cables remained the same.

It's a freshly unpacked board and I was extra careful to check phases and connect everything right (it's the 14th printer I'm building).

Tried with sensorless homing on and off.

One interesting thing is that when I connected a spare motor (same as the others) to X and set it to M350 X4 it did spin but in random directions, i.e. 3 times clockwise, 1 time counter-clockwise, while I was pressing X+10 on the Web UI while spinning it was also reporting the nasty short-to-ground error.

I humbly ask for guidance.

@dc42 I made the change - please take a look - English is not my first language.

Thank you. I got it to work. Had to plow through the datasheet to configure all the CFG pins (that are relevant in the "standalone" mode) to achieve the mode I wanted without any motor whining.

Should I document that somewhere?

The Maestro Expansion aside then. If I were to add TMC2130 (which are SPI) how would I set i.e. the spreadCycle mode for them in a Duet config? Or is that unsupported and would require firmware changes?

Thanks.

It's printed on the solder mask

Is it possible to "talk" to TMC UART or SPI drives as one would from a Marlin?

Hello.

I saw a hew topics created around this and the great article https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers. Since I'm working on something (for the community, if someone is interested, a 3 Z belted design as an addition to the linked thing is what I'm working on) that would require 6 drives and I only have a Duet 2 Wifi with no option to get anything else due to the crisis I would like to figure out a temporary installation for a 3 Z assembly with only what I have lying around: a Maestro 2 stepper expansion (still available in a store I can reach) and a few things I have already - some 8-bit MKS boards with TMC2130, TMC2208.

The question is should I go for the Maestro option and use that as a custom expansion? Or is it not advisable? I would like to try with those little stepper driver boards but the "up to 9V" sign scares me - I'm using 24V.

I understand that a DUEX2 is the way to go or even a Duet3 but until this sad thing ends I can't get those and I don't want to be blocked with this project of mine - it's a coping mechanism for me and I think some other people as well. Good people I ask for guidance (and a little bit of friendship as well I think )

Thank you,
