After the 6HC + 6HC combination did not work woth the boards I had, I tried a 6HC v1.01a (mainboard) + 3HC (expansion1) + Mini 5+ (expansion2).
The toolchanger nog gives good quality prints with all 4 tools.

@dc42 I did some further testing today and it seems I spoke too soon in saying the issue with print quality was solved.

When the 6HC 1.0 acts as expansion, it controls extruders, fans, temp & heat for thee of the four tools. I follow your logic in thinking temperature input problems on the board causing the described quality issues.
With the 6HC 1.0 as mainboard its main task is to drive the motion system. Now I have issues where extruders are skippings steps intermittently and prints getting knocked off the bed halfway through a print.

Do you think it is possible that the 6HC 1.0 is faulty in more ways, causing these issues?

@jay_s_uk thank you for the suggestion. I am already running 3.6b2 on all the Duet boards.

Update:
I tried one last board setup that I hadn't tried yet, using the 6HC v1.0 as mainboard and the 6HC v1.01 as expansion board (revering the role of the two 6HC boards).
This yielded surprising results with good print quality. All tools are printing just fine!

So the issue is solved, but I'm still curious as to why there were print quality issues when I used the v1.0 6HC as expansion board. Any clue?

Hi,

I'm trying to get a combination of a 6HC v1.01 mainboard + 6HC v1.0 as expansion to run 4 extruders for my Jubilee toolchanger. I came from a setup with 6HC v1.01 + 3HC v1.02a with three tools running on the 3HC board.
After some problems getting all stepper motors running all the hardware seems to be functioning. (Thanks again droftarts & dc24)

Now I'm having print quality issues that I didn't have before. Every print I do shows a number of issues, including underextrusion toward corners, overextrusion on corners, messy top- layer, etc. This happens with all tools on the printer. The pictures show the difference in print quality.

I tried a few things in a effort to find the cause.
Change the expansion board back to the 3HC in order to rule out any mechanical/wiring fault: This resulted in good print quality on all tools like before.
Next I tried a combination of the 6HC v1.0 board + 3HC in order to see if thee 6HCv1.0 board had a fault: Again good print quality like before on all tools.
I'm running RRF 6.3.0 beta 2 on all boards, and have used the same wiring, filaments & print setting to exclude any issues there.

Any idea what could be causing the drastic difference in print quality?

Config.g for the 6HC v1.01 + 6HC v1.0 setup
Config.g for the 6HC (v1.01 or v1.0) + 3HC setup
M122 for the 6HC v1.0 + 3HC setup

@dc42 Thanks for the tip! I'll definitly include the S4 command.

@droftarts Thank you for pointing in the right direction. Just updated firmware on both boards to 3.6.0beta2 and all extruders divers are working fine again.

Again thank you for your help!

Hi,

I'm trying to run a 6HC v1.01 mainboard + 6HC v1.0 as expansion to accomodate 4 extruders on my Jubilee toolchanger, but I'm having trouble getting the extruder motors to work.

Until yesterday I had a working system with the 6HC v1.01 + 3HC v1.02a, with three tools all running on the 3HC board.
I changed the 3HC for a 6HC v1.0. All changes were made to enable the 6HC to run as an expansion board: congif.g for the expansion board with only the M954 command, both boards running RFF 3.5.4, and congif.g for the 6HC v1.01 mainboard was changed to accomodate for the changed adresses for the fans. M122 report look fine:

6HC v1.01 mainboard:

Issue:
None of the extruder motors respond to any extrusion command when the appropriate tool is selected & hot.

Checked fans, themistors & heaters: working properly.
Checked extruder motors and drivers on the 6HC v1.0 board: working properly when configured as a axis instead of an extruder.
Then I started to check in the config.g file to see if I missed anyhting in configuring the tools.

...And that's where I'm stuck.

Can someone please take a look at my config.g to see if I'm doing anything wrong?
I'd really appreciate the help!

@dc42 I'm located in the Netherlands and of course I'll provide the board including SD card. Please contac met via email or other non-public way to make futher arrangements.

@dc42 In one of the earlier threads I reported having this issue on RRF 3.5.3.
I now temporarily swapped my Mini5+ WiFi for a 6HC since I have a project due.
I'd be happy to lend out my Mini WiFi if that would help you to eg. reproduce the issue and find a solution?

@dc42 I upgraded to RRF 3.5.3 today. During the 2nd print I experienced a hard reset. Please see the M122 report underneath:

@droftarts I reverted to RRF 3.4.5, DWC 3.4.5 and WiFi 1.27 as you suggested and the results are not improving.
I dug a little deeper into the forum and found this article about similar symptoms. Although the root cause is very different (and not possible since I don't use an SSR), the direction in which @T3P3Tony was searching might suggest a hardware fault.
Could this be worth having a look at or does that seem too unlikely?

@droftarts I downgraded succesfully to RRF 3.4.6.
The first print I ran stopped at layer 4 and the mini5+ reset itself. After trying to run about 20 more prints I notices a few things:

during most prints the duet still resets mid-print.
the point at which the reset occurs (print file progress) it different each time.
only prints with a single object alway succeeed.
prints with mutiple objects are sliced to print 'all at once'

Unfortunately it doesn't make things any clearer to me. Any suggestions?

@droftarts Hi Ian. Thanks so much for your quick reply.
I usually keep a log of all the firmware files I've installed over time so I'm quite sure I have this issue with RRF 3.4.6 as well.
To doublecheck I'll downgrade to 3.4.6 and post the result tomorrow.

I forgot to mention that the issue started while I was running firmware v3.4.6. Unfortunately upgrading to v3.5.2 did not fix it.

Since a few weeks my Duet 3 mini5+ randomly resets during a print. This happens mostly during the first layer, sometimes during the second. I've been running a series of prints using the same set of gcode files and seemingly out of the blue this problem is happening almost every print I try.

My printer is a modified Ender 5 with a Duet 3 mini5+, BLtouch clone and an E3D Hemera direct drive printhead.
I currently use a standard E3D .4mm nozzle with a generic brand PLA and I've never had any problems with it before.

Since I know the gcode files are OK I started looking for a hardware fault.
Most logical cause I thought to be the power supply, so I replaced it. The new one is much more quiet so I'll be keeping that one anyway.
Checked all the wiring & connections for faults, but couldn't find any.

I'd really appreciate any help in finding the problem here. I've got a project tot finish before christmas for the 100+ members of my sports club so I'd like to get this fixed really soon.
I've included the config.g file and the M122 diagnostics file after a reset occurs.
