Drivers clunking sound and toolboard disconnecting
So I have been having trouble with my Duet 3 ecosystem. I have a Duet 3 6HC and a toolboard with the distribution board that it is connecting to. Everything works and it will randomly succeed at a print but most of the time the stepper motor will stop after around three layers and the printer does not seem to notice that it is disconnected. I can hit the emergency stop and it will send up a ton of messages saying that it is no longer connected and I have to unplug it and completely restart everything to make it work for a few more layers. So that is the first problem.
The second problem that I am having is that something is clunking loudly somewhere in the X or Y gantry I believe. This is an electronics upgrade and this sound was not there beforehand so I do not think that it is a problem mechanically. I am running a ton of steps per mm (dual precision setup plus 0.9 degree stepper motors) so would this cause this kind of issue? (Video shows a dry run to make sure it wasn't the nozzle hitting anything). Any help would be greatly appreciated, it has been enough of of a chore to set up and I cannot seem to find the problem.

Is it the stepper motor on the tool board that stops, or another one?
When it stops, does the red LED on the tool board continue to flash in sync with the red LED on the main board?
What firmware versions are you running, on the main board and on the tool board? if they are less than 3.1.1 and 3.1.0 respectively, you should upgrade them.
Please post your config.g file.
Thank you for the quick response. For the toolbooard, it is the extruder motor turning off, and the led is no longer synced with the main board. It acts like it is all completely unplugged randomly. Firmware for toolboard is 3.1.0 and the main board is 3.1.1. The clunking sound is from the X and Y motors too, the toolboard doesn't seem to have an effect on that one.

M350 X256 Y256 Z256 E256 I0 ; configure microstepping without interpolation
This is overkill and puts unnecessary load on the cpu. try standard x16 with interpolation.
M308 S0 P"121.temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin 1.temp0
M308 S1 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp0
B4138 is the default and wrong for your thermistors.
@Veti thanks for seeing that, it worked! No more weird clunking, that makes sense that it was overloading the cpu. For the temp sensor I changed it to B4725 thanks for pointing that out too.

assuming you have a semitec 102-gt2 you also need the C values
@Veti Okay thanks again, I finally found page telling me more about that setting.
