Displaying Water Temp. Virtual Heater Help

[Jordan_Miller41]

Browsed through some threads about virtual heaters in RRF3. Not sure I completely understand, so I'll ask the experts to help instead of beating my head against the wall for hours.

I have 2, 10k water temp sensors (hot/cold) for my loop. Just trying to get those to display in the temp graph/be able to see the temp readout and split.

Running Duet 3 MB with Daughterboard. Sensors are plugged into Daughterboard slots "temp_0" and "temp_1".

What command(s) do I need to add to get this to display.

Thanks in advance.

This is my entry for my temp sensor on my coolant loop.

I guess their names is P"1.temp_0" and P"1.temp_1" respectively. Some daughterboards have other numbering, like '20'.
When you want to see them in DWC, click tools + extras and select the temps you want to see.

@jordan_miller41, what type of temperature sensor are they? The daughterboard connector is for SPI-connected sensors.

[Jordan_Miller41]

@dc42 Spi? Here is the link the two I have.

[Jordan_Miller41]

@o_lampe correct with the "1.temp_0" and "_1", looked in the "+Extras" and I haven't been able to get them to show up yet.

[Jordan_Miller41]

@nuramori Ok this might be a silly question, but how hight can the "S" value go up to? I currently have:

Mainboard

• Bed Therm. = Temp_0
• Enclosure Therm. = Temp_1
• Mosquito Liquid HT Therm. = Temp_2
• E3D V6 Therm. = Temp_3

Daughterboard

• Water Temp 1 (cold) = 1.temp_0
• Water Temp 2 (hot) = 1.temp_1

So would, under the daughterboard section, S equal S4 =cold & S5= hot?

@jordan_miller41
what type of daughter board is it? because if its a PT100 or Thermocouple daughterboard, your pin names are wrong.
They should be either spi.cs0 or spi.cs1

Thanks, that is a 10K thermistor. Is the "daughterboard" a EXP3HC board, or something else?

[Jordan_Miller41]

@jay_s_uk its a 3HC 3 expansion board.

[Jordan_Miller41]

@dc42 Yes, sorry, EXP3HC board.

[jay_s_uk]

@jordan_miller41 aha, that makes sense then.
daughter boards are something else entirely https://www.duet3d.com/PT100_DaughterBoard

@jordan_miller41 said in Displaying Water Temp. Virtual Heater Help:

Then you need a command something like this:

M308 S10 P"1.temp0" Y"thermistor" T10000 B3988 A"Coolant" ; Configure coolant sensor

S10 here is the sensor number that you assign to it, which can be any sensor number not already in use by another M308 command.

[Jordan_Miller41]

@dc42 awesome thank you, I think that clears it up, will test soon to see results.

[Jordan_Miller41]

@dc42 Here is what I input like you said, I am not seeing them pop up in the "extra" section. What am I doing wrong here?

M308 S11 P"1.temp1" Y"thermistor" T10000 B3988 A"Coolant Hot" ; Configure coolant sensor hot side

I just caught this too, when restarting the board to get new code changes it pops up for a split second and then disappears. Watch it here: YouTube

[Phaedrux]

Please send M98 P"config.g" and report the results. That should show us all the syntax errors in config.g

[Jordan_Miller41]

@phaedrux said in Displaying Water Temp. Virtual Heater Help:

M98 P"config.g"

[Phaedrux]

Can you post your full config?

Have you set the can address of the 3HC?

https://duet3d.dozuki.com/Wiki/CAN_connection

Can you send M122 and M122 B1 and confirm they are both using the same firmware version?

[Jordan_Miller41]

@phaedrux
I haven't messed with it physically, it was set to what you see in the picture from the factory, which I think is = 1 based on the chart?

I see the daughterboard's firmare is different. I assume that may be the issue?

[Phaedrux]

Since you're using the SBC you can try sending sudo apt update sudo apt upgrade and see if it detects and flashes the 3HC. If it doesn't, you can try manually flashing it by sending M997 B1.
