Duet 2 Wifi 3 Heater control using bed output + messed up tools

[mikep91]

Hey everyone.
I have tried setting up a hotend with 3 heaters - I am getting some messed up tools it seems.

When i PID Tune heater 1, it turns on heater 2.

It doesnt show heater/tool 3 on my display but shows it in DWC - However i have multiple tools for some of the heaters.....

Config:config.g

I am beaten - no matter what i change my heaters and sensors does not match up.

Also after switching to 3.4.6 i cannot even heat up my 3rd heater - it heats too slowly...

I tried doing the aututune - but then figured my heaters and sensors doesnt match up...

Anyone?

; Heaters
M140 H1 ; disable heated bed (overrides default heater mapping)

should be
M140 H-1

@DIY-O-Sphere

Yeah i enabled it to check if my 3rd heater shows up in that spot - that happens some times... :S

[DIY-O-Sphere]

@mikep91
You are mapping heater1 to the bed....

[mikep91]

Yes I need to use the "bedheat" output to heat up my 3rd heater as the two other heater outputs is used.

However I am mismatching sensors, tools and heaters somehow in my config, so nothing aligns up :(!

This one bedheater shows 101c but that doesnt show anywhere in my DWC - vise versa

Try that

@DIY-O-Sphere

Does not work properly either.

I think maybe my heaters, sensors & tools is mismatching somehow.

When i PID turned heater 3 it didnt heat properly either.

[DIY-O-Sphere]

@mikep91

I suspect the firmware is confused because it is not a complete configuration.
Maybe you can describe what you want to do.
As I understand it, you only want to control 3 heaters?

[mikep91]

@DIY-O-Sphere

Yes i want to control just 3 different heaters (all for an extruder/hotend), one from the bed output on the duet. two others from the regular E outputs.
and all with 3 different sensors - PT100 on the duet aswell

Then i want to map the 3 sensors and heaters to heater 1 2 and 3 , but it keeps turning up as they are mixed up, or one of them on the bed heater output...

Looking something like this:

M308 S0 P"spi.cs3" Y"rtd-max31865" ; configure sensor 0 as PT100 on pin spi.cs3
M950 H0 C"bedheat" T0 ; create nozzle heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H0 S280 ; set temperature limit for heater 0 to 120C

M308 S1 P"spi.cs1" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs1
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 1 to 280C

M308 S2 P"spi.cs2" Y"rtd-max31865" ; configure sensor 2 as thermocouple via CS pin spi.cs2
M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2
M307 H2 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H2 S280 ; set temperature limit for heater 2 to 280C

I am quite confused of the P1, P2 and how to configure them to the correct "tool" in the dwc and duet display - so i am sure my heaters match etc.

M563 P1 H0 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 H1 F0 ; define tool 2
G10 P2 X0 Y0 Z0 ; set tool 2 axis offsets
G10 P2 R0 S0 ; set initial tool 2 active and standby temperatures to 0C

M563 P3 H2 F0 ; define tool 3
G10 P3 X0 Y0 Z0 ; set tool 3 axis offsets
G10 P3 R0 S0 ; set initial tool 3 active and standby temperatures to 0C

@mikep91
The tool count starts with 0.
So P0 Is tool1

[Phaedrux]

Also make sure your firmware is update and that DWC version matches. You should also update your paneldue firmware.

[mikep91]

@Phaedrux

Paneldue is up to 1.25 now this was updated and works great!

Looking at the PT100 - which side is spi.cs1 & which side is spi.cs2? when i plug another one on top - i suppose that becomes spi.cs3&4?

[Phaedrux]

The sides have silk screen labels of RTD1 and RTD2.
And yes when you stack two of them the next ones are spi.cs3 & 4.

[Phaedrux]

@mikep91 said in Duet 2 Wifi 3 Heater control using bed output + messed up tools:

Paneldue is up to 1.25

Should probably update to the 3.x firmware there as well.

[mikep91]

@Phaedrux

The 1.25 works on 2x setups with only 2 heaters - I am only having problems assigning the heaters on the 3rd setup that needs 3 heaters.

Could a problem be that i start up by assigning H0? Looking at the duet display - i am using the 3 marked heaters. - e0heat - e1heat and H3 "bedheat"

[Phaedrux]

Why are you using the expansion header? Why not the actual bed heater output?

[mikep91]

@Phaedrux

It is for controlling a 3 heater hotend (Dyze Pulsar)

Therefor I am turning off the bed heater - but my tool mapping seems to be wrong so i keep getting the 3rd temperature on the bed heater output instead of a 3rd tool - and at the same time I'm get them mismatched somehow....

Will do some wiring checks and numbering of wires tomorrow hopefully sort it up.

Am not using heated bed - so I know I should do a H-1 to turn it off. but the mapping seems to go on that tool

[Phaedrux]

Are you using a heated bed, or not?
