lol, Yea that was the problem.
I don't remember buying a different sensor and all my backups have a thermistor setup. Must not have saved a backup before.

I've dropped the T value to 1000 and that puts it around 23C.
But when I set the heat to 200 and turn the heater on the measured values drops. Same if T is 100000. The measure value starts dropping.
Did I somehow screwup the board when I replaced a pin, 1) VIN on E3 was shorted?

@dc42 the moment I power up the duet it shows 159/158 and stays at that reading

@phaedrux
I've used an different thermistor and connected it directly to the board and I'm getting the same result.
I switched to the other port and same number

FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 3.3 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2021-06-15 21:47:09

What I mean by off is I turn by printer on after hours if not days of it not running and it'll start of at 160.
I've changed the B value up to 1000000, and that dropped it down to 29C.

Could the board connection be bad? How could do I switch it to use E0, the other heater?

@jay_s_uk
I did have the R value on then took it off to test that theory no change.

I've reconfigured my settings for a different problem see post
https://forum.duet3d.com/topic/24741/duet-maestro-driver-expansion-underpowered?_=1629790395857
Now my hotend is reading 160 when off. I have a hermera e3d hotend with the duet maestro board.
Is there anything wrong with my settings?

@phaedrux
awesome that worked It's homing and everything is moving in the right directions.
The steppers are sounding a little grinding, i'm not sure if that's quite the right word.
But they aren't running as smoothly as they have been, would that have to do with the interpolation, or current...?

I think this is working better.
I'm having problems with the homing for this new config.
It mostly only moves the z axes when I home x and y, but they move correctly when manually jogged.

It's a corexy style printer.
x is driver 6
y is driver 5

Here are some of the files.

I've added the driver expansion to the maestro board. All the motors I've added to it act like they are under powered. It makes a grinding sound like it when it's hitting an object but if I give it a slight push it moves just fine. These motors work just fine on the board itself.
I'm trying to move the x y axis with it.
Is the expansion faulty?
