i got the bed Thermistor working already and that one and a normal roomthermometer are showing both about 22 degree

just checked that out, got a measure About 115ohm.
thats to much isnt it? the sensor should have exactly 100ohm didnt it?

So i need a new sensor?
where could be the bad Connection? should i try to Change the cables between the pt100 and the duet?
are there any specific cables for this Connection?

Hey Guys,
atm iam upgrading our selfmade 3D Printer at work with a Duet2Ethernet.
With this upgrade we wanna use a PT100 sensor, i got the pt100 daugtherboard and a new sensor.

Ive tested the daugtherboard with the 100ohm resistor and got a measure about 0.2degree.
Then i pluged in the Sensor (it was a 2 wire sensor) and i got real bad measure, at room temperature the sensor showed up about 90°.
So i did the 4 wire upgrade with the sensor, with the hope to fix this fault.
Now i got the 4 wires pluged in and the sensor shows about 40-70° at room temperature.

So i tried to fix this with setting a "R" in the M305 in my config and it works, the sensor showed up 23°(thats okay) with a R370 but somehow if i shut down the printer and switch it back on the measure is freaking out again. The R370 is still in the config. i tried again and got about 22° with R320, switched off and on the printer
same game, the pt100 is freaking out again and again.

i checked the resistance from the cables near the duet up to the sensor and got a measure about 116ohm.
i checked too to save the changes in the config correct.

i just dont get it why the sensor is freaking out after every restart.

hope u guys can figger out for what iam to blind for
best regreats

Damn u are right! I just asked the seller to check if it was the right Hotendkit they sent me....and its a 12V, not the 24V i ordered.

Hey Guys,
i did the PID Tuning for my Heatbed and my Hotend and both wokred fine. There was no Errormessage and i was able to save the Parameters.

My Heatbed is working pretty well but if try to heat up my hotend ist overheating about 10-20° and a Error is showing up: Falt on Heater1 Temperature is exceeded

I tried to do the PID Tuning again with a lower P (0.1), but with this Parameter i cant finish the Tuning cause my Targettemperature isnt reached. The Tuning worked fine with P0.15 but i cant print with this stats.

I got a Duet2 Ethernet and a orginal E3D Hotend.

@dc42 i found the problem, the X Driver looks like it died from overvolting or something like that.
But i cant figger out how this could happen, cause the Printer was working fine until i tried to do the PID Tuning.

@dc42 i also get the Error if there is no motor connected!

The Wiring seems to be okay.

I really dont get it, the day bevore the homing works fine.

Hey Guys, my Duet2 Ethernet is spamming the Error:

"short-to-ground on Drivers 0
Over temperature shutdown on Drivers 0"

The first time this error occurred was during PID Tuning of the Hotend.
And that makes no sense to me, because the Driver0 drives my X Stepper and this has nothing to do with the PID tuning or am I wrong?

During the PID tuning, a short sound was heard as if the board was restarting.

I bought this Board just a few weeks ago from Makerdise and the Makerdisesupport told me to open a Thread in this Forum!

When I went home from work I will upload Photos from the Board and Driver0.
