What is the max operating/environmental temperature of the Tool Boards? Can they be used in heated enclosed chambers?

@dc42 @Phaedrux

Changing M106 H3 to H5 did work! Wow thank you both so much for the help! You guys at Duet are awesome! Have a great weekend!

@phaedrux

if you want me to post the entire thing i can....but this is what i have with what pertains to the chamber heater.

M106 P4 S255 H3 T30 C"Chamber_Fan" ;Chamber Fan enable thermostatic mode for chamber heater

Using RRFW 3.3

I am trying to configure a fan so that it is thermostatically controlled by a sensor that is associated with but not directly assigned to a heating element and having some trouble figuring how to go about this.

I have a large chamber with a powerful heating element where the surface of the heating element gets much hotter than actual chamber temps, that is until the chamber temps can rise and even out to set temps. In order to spread the heat from the element i have a blower fan mounted to the heating element. A soon as the heating element gets a little over 28-30c the fan needs to also kick on and remain on until surface temp of heating element drops back below 28-30c.

I have 2 thermistors associated with this chamber heater...one is actual surface temperature of the heating element itself and the other is to monitor actual air temps in the chamber, which at startup can vary drastically like nearly 180c difference. I currently have the heater configured in M950 to use the air temp probing thermistor as i want to maintain chamber air temps accurately....so surface temps initially get much much hotter than chamber temps...instead of just having the blower fan on at all times i want to configure it to be thermostatically controlled by the sensor mounted to the chamber heaters surface which is not the sensor assigned to this heater...and thermostatically controlled configuration requires a heater # to control.....I have attempted to just configure the fan using Chamber Heater w/ Air probing thermistor but seeing as the fan doesn't kick on to spread the heated air until the chamber temps reach specified temps the actual heating element itself gets to something like 200-220c before the fan kicks on to spread heated air throughout the chamber.

Should i be looking into setting up virtual heaters? Or a virtual tool? Or conditional g-code?

@dc42

That did the trick! The updating wasn't too bad either. Link listed below for how to for convenience of others. Again thank you very much for the help!

@dc42
You are the best thank you very much!

@dc42
Where is the firmware located? Im on Github...

Is it under

Duet3D/Duet3Expansion? or Duet3D/RepRapFirmware?

@dc42
by chance can you link a good how to on this?

@dc42
Thank you I will do so and report back!

@phaedrux

To be clear these sensors/thermistors are not assigned to a particular heater. They are just sensors im using to see how even my chamber heats. The sensors are plugged into the 3HC Expansion board...at this time no other heaters or sensors are connected to the expansion board....just these 2 thermistors. Not sure if there are FW limitations on the 3HC EXP where a temp sensor must be assigned to a Heater or a Tool on the same board?

I have a question hoping someone can point me in the right direction about.
Using a 6HC Mainboard and a 3HC EXP board.

I have a heated chamber and wanting to setup 2 thermistors that probe the air in different parts of the chamber.

I have two thermistors plugged into the exp 3hc into temp0 and temp1. I have the exp 3HC CAN address set to 1. I have my thermistors addressed as such:

M308 S3 P"0.temp0" Y"thermistor" A"Keenovo_Temp" T100000 B4138 H0 L0 ;Keenovo Pad thermistor - connected to Mainboard temp0

M308 S5 P"1.temp1" Y"thermistor" A"Upper_Chamber_Heater_Temp" T100000 B4138 H0 L0 ;Chamber Thermistor - connected to EXP temp1

im getting an error on CAN addr 1

Error: M308: Response Timeout: CAN Addr 1, req type 6031, RID=0
Error: M308: Response Timeout: CAN Addr 1, req type 6031, RID=1

Assuming i have this addressed wrong...,but i did some google searches on the error but not much turned up....any input or can someone point me in the right direction to find a list of error codes?
