M563 Max extruders on tool
-
@deckingman It's not a 3d printer that I'm building but a machine that extrudes paint. The 12 drives are configured as one tool but that tool has 6 nozzles that extrude at the same time with 2 extruders on each. I use machines like these to create artworks.

@kcorbedsellig would love to see that!
Yes, for the firmware update, just upload your .bin file in DWC. It should ask you if you want to install it.

@droftarts Thanks, I'm sure I can make that work.
You can see works from a similar machine here.

I've just tried to upload my .bin file through the DWC and it failed. Just for sanity, I tried it on a second board but without success again. I now can't connect to either of the boards. In both cases, the DWC still loads but fails to connect and shows the following error:
My .bin file is called "Duet3Firmware_MB6HC.bin" and found in "RepRapFirmware/Duet3_MB6HC/". It's 792KB which seems to match the ones found online. The only thing I changed is the variable discussed above.
On one of the boards, the diag led flashes 3 times followed by 2 sec of no flash.
On the other which is a newer one the diag led does not flash at all.I've tried connecting through SSH to go back to an older version but can't seem to get it to work. It keeps telling me everything is up to date.
I now have two boards that don't respond and can't seem to find out how to flash stable firmware back on them. What's the right way to get these back to life? I have a third one I can try but I'd rather not.

@jay_s_uk thanks, I've quickly tried to get this going but can't get a serial connection with the boards, and can't get Bossa to run on my Mac either, will have to do this some other time and dust off the old PC I must have around here somewhere.
Unfortunately, this does put me in a situation in which I can't seem to get the firmware changed myself but I also can't proceed with only 10 extruders. If I understand @dc42 correctly the next firmware update could allow for 12 extruders but I imagine that could take a while to become available.
Any chance anybody who feels comfortable altering the firmware could build a version for me that has the 12 extruders per tool allowed? I'm on my last development board now so I can't risk uploading a faulty version created by myself again.

@kcorbedsellig Macs have a particular problem flashing the 6HC; we’ve tried to update Bossa to work, but it steadfastly refuses. However, if you have an SBC, you can flash it from that, using the terminal command line version of Bossa. You’ll need to manually erase the board using the erase jumper first. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#all-other-duet-boards specifically the Bossa > Linux and Raspberry Pi tab.

I've got the custom firmware working.
The issue was that CrcAppender needed '.NET runtime' to work. After installing that separately and confirming in the terminal CrcAppender worked without errors the rebuild firmware worked. It took some time to figure this out because Eclipse reported no error for it.
Thanks for all the help.

@kcorbedsellig I'm glad you got it working. I've added a note to the build instructions for RRF that the .NET runtime is needed by CrcAppender.
I've increased the maximum number of extruders to 12 in the source code for the 6HC and 6XD builds, so from the next release onwards you won't need to build RRF yourself.
