Hi droftarts.
Thank yoo - I think i will need to do some heater feedforward when time is right. For now I will need to find the reason for the flickering temp values and so I can perform a proper PID tune.
Are there anywhere i can measure resistance on the PT100's to see if they are having the correct resistance or if i should put in a resistance of some sort?
We are running quite long cables for the PT100's but they are shielded.
I switched out the PT100 daughterboard and now the 2000c sensorshort is gone.
However when tuning Heater 1, I am getting quite a large overshoot.
This hotend is a Dyze Typhoon with 2 heaters - When FLOW increases fast my PID tune becomes worthless.
Would it be better to tune in this manually?
I do NOT have any fans connected that will turn on or off when doing the Autotune.
Hey everyone.
I am having some problems on one of 5 printers with the exact same setup.
We are having very long cables to allow us to put our DUET outside our chamber, this causes some problems on one of our setups.
Problem 1 - Small flickering of temperatures makes it impossible to do a proper PID tune:
Problem 2 - IF heating the chamber - I am getting flicks to 2000c almost every 10 seconds which causes the firmware to turn the heater into fault state:
I am wondering if we should connect the PT100's with more wires, or with a small resistance in between it? Right now we have shielded cables for the PT 100's.
Can i measure the resistasnce somehow in the PT100 to check if there is any fault?
It is very clear when heating the chamber - my faults come more often than if it is not heated. However I am getting the errors no matter what.
Thank you in advance,
Mike
Hey Phaedrux.
I have one Paneldue with 3.4.1 and this display is not working with any of my Duet's (3.4.6).... Therefor I dare not to upgrade the other ones, before this one display with 3.4.1 works...
Thank you very much for your config. I will look through mine for errors.
You are absolutely correct, i need to 3 heaters to be assigned to 3 different tools to allow for seperate control.
Thank you - will report back!
@Phaedrux If i define them all as BED i can only turn them all to the same temperature. I need to be able to put my top heater to IE. 190C- middle heater 210C and nozzle heater 230C - as an example.
Hi deckingman - thank you for jumping in.
I am using a duet to control some different hotends. Some with 2 heaters and some with 3 heaters.
I am having the problem that i cannot turn on my tools on my paneldue with my 3 heater system.
I can turn them on in my DWC. But when I'm looking at the display of the 3 heater one: I dont have the option to toggle the tools on/off - I am 99,9% sure my tools is not defined properly....
Not able to turn on tools: (3 heaters)
Able to turn on tools: (2 heaters)
On the one with 3 heaters; i have no option to turn on my tools.
Config of 3 tools: - Only working on WIFI.
M563 P3 D0 H1 F0 ; define tool 2
G10 P3 X0 Y0 Z0 ; set tool 2 axis offsets
G10 P3 R0 S0 ; set initial tool 0 active and standby temperatures to 0C
M563 P1 H2 F0 ; define tool 1
G10 P1 X0 Y0 Z0 ; set tool 1 axis offsets
G10 P1 R0 S0 ; set initial tool 1 active and standby temperatures to 0C
M563 P2 H3 F0 ; define tool 1
G10 P2 X0 Y0 Z0 ; set tool 1 axis offsets
G10 P2 R0 S0 ; set initial tool 1 active and standby temperatures to 0C
Config of 2 tools: Works both on Wifi and on the paneldue:
; Heaters
M140 H-1 ; disable heated bed (overrides default heater mapping)
M308 S0 P"spi.cs1" Y"rtd-max31865" ; configure sensor 0 as PT100 on pin spi.cs1
M950 H1 C"e0heat" T0 ; create nozzle heater output on e0heat and map it to sensor 0
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 0 to 120C
M308 S1 P"spi.cs2" Y"rtd-max31865" ; configure sensor 1 as PT100 on pin spi.cs2
M950 H2 C"e1heat" T1 ; create nozzle heater output on e1heat and map it to sensor 1
M307 H2 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H2 S280
Hope this makes sense.
Thank you!
That is handled externally aswell.
The heat from different zones affect eachother.
I will need to define the tools somehow - to be able to turn on the "tools" on the duet display.
This setup works for a 2 heater control board:

Heater 1 from the 3 heater hotend returned with some new values:
I think the dead time seems crazy - however this is a quite big hotend and big long cables.
M307 H1
Heater 1: heating rate 0.740, cooling rate 0.088, dead time 49.43, max PWM 1.00, mode PID
Predicted max temperature rise 482°C
PID parameters: heating P4.9 I0.020 D168.9, steady P4.9 I0.039 D168.9
Hello everyone
When tuning PID Sensors for a hotend in 3.4.6;
Will it be problematic if I do not have a cooler/fan setup for my setup during the PID tuning?
I feel like it is taking forever.
It seems like my config-override.g is not being read either.
2 Heater hotend:
M307 H1 A340.0 C140.0 D5.5 S1.00 V0.0 B0
M307 H2 A340.0 C140.0 D5.5 S1.00 V0.0 B0
3 Heater hotend:
M307 H1 A940 C810 D22 S1.0 B0
M307 H2 A940 C810 D22 S1.0 B0
M307 H3 A795 C920 D10 S1.0 B0
These values I have from the manufacturer of the hotends
I had to map the heater 1 to the bed to get all 3 heaters to work... I am sure there is something wrong with my tools still.
I can only set the temps via DWC - not on the board anymore - how would I go about changing this?

IIT WORKS !!!! XD
Almost.......
Heater 1 and Heater 3 is mismatched - should i remap these in the software or on the duet?
I restarted the controller and now I am having no tools: :(........ either on the duet or in the DWC
