@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
-
@Charles-Fraser take this file:
Duet3Firmware_MB6HC.bin
From here
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5and upgrade using the System->Upload System Files
-
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?
-
If you get the "Duet3Firmware_MB6HC.bin" from
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5And 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
-
Okay we are beta 5 across the boards

@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.
-
Yup all is heating up now with just a heater fault. there is nothing in the console about those faults. We could run autotune PID for the bed because that is set up but it's on bangbang mode so I wonder if that still has PID? I guess it must right?
I still havn't found a 3mm x 15mm p1000 but I will find one. Perhaps we can move onto the endstops now? I'm not sure which way around the wording convention indicates I have set up my end stops (again a diagram would be helpful) but perhaps there is a way I can test that is working and then start to do motor configuration after that? My thanks again!
Charles

In fact on closer inspection, when the bed fault comes on the bed stops heating
-
@charles-fraser
I would expect a report something like this in the DWC console when the bed hater faults:Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/secTo tune the bed the documentation is here:
https://duet3d.dozuki.com/Wiki/M303an example is
M303 H0 P1 S60Send this in the console - it will take a while to run and you will see the temp cycle. once its finished the send
M500in the console to save the results to config-override.gWe can also look at XY endstops (Z probe is out the picture for now as you said)
With the Axis not at their limits where the ends tops are send
M119from the console and see what is reported. Then with each of the endstops triggered in turn, sendM119while they are triggered and see the response in the console. -
Thanks, there is no report of error in terminal re noz heat failure:
I have completed PID tuning and I get (pls NB this is a mattress sized heated bed in a breezy tent!):

When I send M500 I get

For now replace the M307 H0 command in config.g with that command, except change to bang bang
M307 H0 B1 R0.138 C790.6 D13.87 S1.00 V24.0 -
@charles-fraser thats fine for now. we can enable config-override later.

Oh wait I added that as a command in the console
How do I change to bangbang?
Just add this?

@charles-fraser yes that looks good.
