@rjenkinsgb thanks Robert J it is grounded as you describe already.

@t3p3tony thanks captain. I have disconected everything from the first extruder Mounting / block and am using the second block. This gets rid of all these low power tingly shocks when I touch the thermistor (not sudden but a painful prickle as long as I hold the thermistor when plugged into that block. I think the noz heater or fan wires must have rubbed down or melted down or something because that whole block is messed up. If you remember the BL-Touch was shorting too (I’m ordering a 3D Touch because it will come with some actual paperwork.

I’ll post the config G file here just now, I replaced all the lines you showed me however. I must have done something wrong. Thanks so much, sorry this is such hard work.

Is anyone at the Additt conference this week? We need to find a manufacture partner for this opensource pellet extruder that Juan has invented. His Spanish partners just dropped out www.recycl3dprint.com

@charles-fraser ok so do you get errors when config.g is run using M98? and are both heaters showing correctly in the U and heating when commanded?

@t3p3tony

I don’t get why the bed isn’t even showing up?

T3P3Tony · 27 Oct 2021, 13:07

@charles-fraser just noticed in your most recent config.g that the command to create the bed is missing, must have been deleted in error. please add the line

M950 H0 C"1.out0" T0
so your heater section should look like this:

sorry i did not spot this earlier.

Charles Fraser · 27 Oct 2021, 13:33

@t3p3tony

Okay so that works! Thanks!

When I set ‘active’ to 50C on the noz and click ‘heater 1m the mosfet light goes blue which means the signal is going to the mosfet from the right heater on the 3HC but after a few secs it just says ‘fault’ so I emergency stop!

NB I still cant find a 3x15mm pt1000 thermistor anywhere! So at the moment I have this rather high tech workaround with the 6x50mm pt1000 where the thermistor is just held against the heating block with some tape so we can at least see if it’s getting warmer. Does this indicate that the heating cartridge is faulty?

Also when I set the heated bed to 30C on the active setting and turn it on it did seem to get warmer (went up by a degree) then reported fault

T3P3Tony · 27 Oct 2021, 13:43

@charles-fraser The faults are probably because the bed and nozzle are not tuned. There is not much point in tuning them right now if thats the case because the setup is not how it will be in normal operation (PT1000 taped to the outside).

When you say you got a "fault" what fault did you get reported in the console?
I cant see anything in the photos of DWC that you upload. its better to cut and paste the text from the console into this thread (using the </> block for formatting.

Charles Fraser · 27 Oct 2021, 13:54

@t3p3tony

So when I set noz ‘active’ to 50 it starts heating and shortly after just says fault where it used to say active:

But if I just leave it it does work, the noz heats up. However when I stop it it says

The same is true for the bed but the bed does not heat up! I’ll try switching the polarity of the wires joining that relay!

Also what is this new: ‘incompatible firmware’ message. I didnt see that before.

T3P3Tony · 27 Oct 2021, 14:27

@charles-fraser lets deal with the incompatible firmware bit and then come back to the heaters.

Please send M115 and M115 B1. copy the results from the console into here.

Then look at the "settings" machine and General to get the DWC and DSF versions.

@charles-fraser ok so when you upgraded to 3.4b5 the mainboard did not get upgraded

T3P3Tony · 27 Oct 2021, 15:13

@Charles-Fraser take this file:

Duet3Firmware_MB6HC.bin

From here
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5

and upgrade using the System->Upload System Files

Charles Fraser · 27 Oct 2021, 15:50

@t3p3tony

Can you please explain exactly how - step by step. Last time I had to totally reinstall raspberry Pi and everything else!

So if I download that file and upload it to the system folder (not the firmware folder) then send command ... what was it again?

T3P3Tony · 27 Oct 2021, 17:01

@charles-fraser

If you get the "Duet3Firmware_MB6HC.bin" from
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5

And then go to the systems page and upload that file using the Upload system Files dialog box it will prompt you to install it. Say yes.

The issues with the Pi before were different. everything else in your system is running 3.4b5

Charles Fraser · 28 Oct 2021, 09:33

T3P3Tony · 28 Oct 2021, 09:56

@charles-fraser ok, now you should not be getting a incompatibility fault and the temp sensors should be showing up. When you heat the heaters you may still get a heater fault. What is reported in the console for those heater faults? if its temperature is rising too slowly then we will fix that when you have the sensors installed in the hotend/bed and we are in a position to tune the PIDs for those heaters.
