@jay_s_uk it might be a PT-1000 then it came with my mosquito, nevertheless that one seemed to work just fine when I temporarily wired it up and changed the B and C values

@phaedrux Sorry for my late response. i'm very busy getting my printer printing usable parts first. but last week i decided to look at fixing the screen. i tried updating the firmware which worked just fine, the screen is getting touch input. when i touch the screen in specific spots it will beep as if i pushed a button. i even accidentally homed the printer this way. anyhow, the problem doesn't seem to be software related. my guess is that the inverter for the back light is broken since the back light doesn't seem to illuminate. the question now would be if a broken back light converter is diagnose able and replaceable.

@phaedrux thanks for the info ill give it a shot

hi there,
after not using my paneldue for a while during my printer rebuild it stopped working when i first plugged it in again. I updated the firmware of my 6hc motherboard to version 3.3.0. when i plug the wires is to the mainboard (the pin-out is correct I checked) the screen doesn't turn on. and if i try to update the firmware of the paneldue to version PanelDueFirmware-v2-7.0-logo.bin using this command M997 S4 P"PanelDueFirmware-v2-7.0-logo.bin" I get the following error Error: Failed to communicate with PanelDue bootloader (no START signal received). Please try again or press the Erase and Reset switches on PanelDue.
i checked the incoming voltage from the mainboard which is 5 volts as it should be.
what could be wrong here ? it is a paneldue v2.01 btw.

It doesn't look like a wiring problem. I m using a toolboard on a Hemera tool so the thermistor leads are about 30 mm long and directly connected to the toolboard. I checked with a spare PT100 thermistor which seems to work just fine + when I check with a multimeter it seems to be infinite resistance. so I think it's just broken. I ordered a new one, I'll let you guys know if that solved the problem. thanks for the help.

I'm setting up a new printer with duet 3. After assigning the hotend thermistor the temperature reading suggests the hotend is -273.1 C which is not the case. what could cause this ? I'm using an 104NT thermistor. When I try connecting a spare PT1000 it seems to read just fine.
config Gcode: M308 S1 P"20.temp0" Y"thermistor" T100000 B4658 C6.5338987554e-08 ; Semtec Thermistor

@t3p3tony alright, I will contact warranty support thanks for your help and I will be more careful next time

@stefvandermeer the Led strip I was using was only 9.6 watts per meter and I was only using 50 mm

@dc42

I bought the board in July in preparation for my upcoming printer build. The board was version 1.0. I am powering the printer with a 24 volt meanwell powersupply, I could provide the model number of this unit when needed. I was just powering a 50 mm section of 24 volt led strip to use as a work light.
I hope this information helps,

Hello,

I am afraid i got fairly lucky while working on my new tool changing 3d printer. I was testing stepper motor functions for a custom tool lift when i was greeted with the smell of fresh burning electronics. after I noticed the smell I killed the power to the mainboard. after closer inspection I was unhappy to see the Z1284PI was burnt. I am puzzled about the cause of this occurrence, the stepper motors I was testing where plugged into one of my 3hc expansion boards. the fact that a component on the mainboard shorted somehow seems odd to me since the mainboard was not powering anything apart from some LED lights. after I killed the power I tried powering the duet with my desktop power supply with the usual 24 volts, the 24 and 12 volt rails where working appropriately but the 3.3 and 5 volt rails weren’t.
before this all motors where working fine but somehow I couldn’t get the sensor inputs to work, but this could also be a problem with the switches I am using.

stuff plugged in: (duet 3 6hc)

steppers on out0 to out5
bed heater on out0
24v led strip on out2
bed thermistor on temp1
panel due on io0
duet 3hc thru can bus
Z end stop on io1
bed probe on io2
tool lift end stop on io3

stuff plugged in: (duet 3 3hc) 1 and 2

stepper motors on first drives of both boards

I hope someone out there can help me out.
thanks in advance

Stef
