Heater fault on new board
-
Just received my new Duet 2 Wifi (from local, genuine reseller ;- ) and fired it up to look at the wonder.
I have no previous experience in 3D printers, nor do I have anything attached to it (that goes for thermistors as well).
I noticed that heater 1 reports error:
(Still no thermistor connected there, board turned off)
Later, I click the Heater 2 label and get:
There is also a notification:
... which gives the hint that the faults are due to missing thermistors.
Those are not yet purchased, but I could use a resistor for testing.Can someone confirm that the board is functioning as expected? (New board, no thermistors)
Thanks.

most likely you have generated a config for version 3 but have not installed rrf3 on the duet.
see
https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmwarealso you need to upgrade to 3.0 first before going to 3.1.1

Thanks.
I'll look into it, but the only thing I've done in terms of configuration is setting up the wifi and then looking at signal strength (M552 variants and M122).BR,

what is missing in your printer?
if you buy a thermistor i would recommend a semitec 104-gt2 or a pt1000

@Veti Basically everything
The Duet is more or less the first component I bought (work in IT, need to get the computer in place before can work kind of approach, I guess), still working on printer design.BR,

without stepper motors, heater, thermistors and fans, you can not really test the duet.

if you need suggestions on which components to get, we can make suggestsions.
a good starting point for parts is the voron bom.

or the blv cube bom

@Veti I'm aware of that. I'm basically just trying to find out whether the immediate faults reported are reason enough to open a case with the dealer.
It's like a new car; the low oil pressure is reported in the dashboard and is visible right away whereas the bad stitching in the seats takes a while to show up. I'm merely acting on the oil lamp before purchasing the trailer to go with the car

you could connect a 100k resistor across the thermistor connector. that would emulate 25C

@Veti said in Heater fault on new board:

That will give you a temperature reading of about 25C; but you will still get a heater fault if you try heating, because the firmware will notice that the reading is not rising when the heater is on.

So you know there are diferent values with different temp sensors and thermistors the pt -1000 can be used directly with your duet. A lot of the cheap,boards use a pt-100 which can't without a daughter board to convert the signal ..when you buy a pt1000 there will be a gcoade entry in the heater section of you config g file you most likely will have to change, that # should be available from the vendor you buy the thermistor from.
