PT1000 on toolboard showing 2000c
-
@jay_s_uk
okay. I moved the heater to the 6HC so its working. -
@jay_s_uk I disagree. I have my hotend heater connected to my Duet 3 and my thermistor connected to my tool board and it works fine.
-
@dhusolo it was a restriction in 3.3.0

To expand on that, it is a restriction on all "3"series firmware versions up to and including 3.3.0 and affects all expansion boards, not just tool boards.
-
I understand that but what I'm saying is that I'm running 3.3.0 and I have my hotend heater on my Duet 3 and the hotend thermistor is on the toolboard.

According to the above, it's a permanent limitation for safety reasons. Maybe the rationale has changed but the documentation hasn't caught up?
-
@deckingman The documentation on the limitation says:
A heater on an expansion or tool board can only be controlled by a temperature sensor on the same expansion board. This is a safety precaution.

So it's the other way around from the firmware limitation, and (apparently) works.

Soooo.....Should I create another post so we can get back on topic?
I have my heater and my PT1000 currently attached and mapped to my Duet36HC, so they are working, when I have attached to my toolboard1LC:

@practac can you post your current config and an output of

@practac your config yesterday doesn't reference the toolboard for the PT1000. so can you confirm that thats definitely the one you're using?
-
@jay_s_uk yes sir it it the same toolboard.
-
This post is deleted! -
@practac no, I meant is the config you posted yesterday definitely the version you are trying to use? Because if it is I'm not surprised it doesn't work. I'm asking because you've mentioned changing things to try and get it to work

You should leave off the T, B and C parameters for a PT1000. Although I doubt whether it will help. This may be a case of ESD damage to the series resistor on the toolboard.
Can you reconfigure your setup to use the PT1000 on the toolboard with those parameters removed?

@phaedrux
remapped temp probe to this:M308 S1 P"20.temp0" Y"pt1000" A"Hotend" ; configure sensor 1 as pt1000 on pin 20.temp0
Still showing Hotend at 2000c
Tried the other temp port on the toolboard with this:
M308 S1 P"20.temp1" Y"pt1000" A"Hotend" ; configure sensor 1 as pt1000 on pin 20.temp0Same results
