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

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.

@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?

mikep91

@Phaedrux

No - not controlled off the DUET - duet is only supposed to be controlling 3 heaters in one hotend

Elaborated in answer above

If you're not using a bed heater you can use the output for your 3rd extruder heater, then you don't need to use the expansion headers, which aren't really intended to be used directly by a heater.

If you don't define a bed heater you don't need a H-1 to disable it.

mikep91

@Phaedrux

Makes sense and would be alot better as the connections on the expansion is quite poor compared to the bed and extruder connections.

How would the M command look for mapping the 3rd heater to the bed instead of the expansion?

M308 S1 P"spi.cs3" Y"rtd-max31865" ;
M950 H1 C"bedheat" T0 ;
M307 H1 B0 S1.00 ;
M143 H1 S280 ;

Something like this - whilst not using H-1 to cancel it out?

Phaedrux

So if I understand your setup, and I'm not sure that I do, you'd have something like this for a single tool, using 3 heaters together, and no bed heater, with PT100 temp sensors.

@Phaedrux

Yeah im sorry for being not very precise - I am using a pellet hotend on a robotic arm, so the duet is only to control the heaters. But it has 3 heat zones - so i would need individual control of each heat zone mapped to a specific sensor.

Would this give me 3 individual heaters to control on the duet display?

I will do a test first thing tomorrow morning with this - thank you!
