Heater Will not turn off once started.

Phaedrux

Yes, and you can either update the Pi to also be 3.2 b4, or flash the duet back to 3.1.1

If you wish to use the latest unstable DSF components, you can run the following commands instead:

wget -q https://pkg.duet3d.com/duet3d.gpg
wget -q https://pkg.duet3d.com/duet3d-unstable.list
sudo mv duet3d.gpg /etc/apt/trusted.gpg.d/
sudo mv duet3d-unstable.list /etc/apt/sources.list.d/duet3d-unstable.list
sudo chown root:root /etc/apt/trusted.gpg.d/duet3d.gpg
sudo chown root:root /etc/apt/sources.list.d/duet3d-unstable.list

Thanks that is what i needed to sort that issue, I upgraded to try and resolve the original issue about the heater recommended by @T3P3Tony ,

I will redo config.g now and see what happens with the heaters.. thanks for your support.

Turricann

OK config.g redone left every thing else default from a clean install on the Pi

On my duet 3 6hc i have the below,
Running on a 24v supply

Out0 - heatbed. - on/off working OK
Out1 - 24v heater.
Out7 - Hotend fan
Out8 - Partcooling fan
Out9 -Partcooling fan (Disconnected)
TEMP0 - Heatbed thermistor(B9350)
TEMP1 - Hotend Thermistor (B4138)
Temp3- Thermistor from Z probe.
IO_0 = pannal Due - currently disconnected.
IO_3 = Z probe Pinda v2 type
Driver 0 = X
Driver 1 = Y
Driver 2 = Z1
Driver 3 = E0
Driver 4 = Z2
Driver 5 = Z3

Thats is everything connected and my config.g is,

@Turricann So with a fresh config and Pi the heater is still staying on once enabled?

But it's not turning on automatically when power is first applied, right?

Turricann

yes that is correct as long as the hotend is below 45 Degrees or fan0 has not got thermostatic control disabled .

If thermal control is enabled and the hotend is below 45 degrees the heater will turn on and off normally,
If its above 45 Degrees the hotend will come on with power.

This is why i came to the conclusion the heater will not turn when the fan is on.

one more thing is if there are no fans set up i cannot control the heater.

Phaedrux

It looks like your config was pasted twice maybe in your last post?

Turricann

One other thing is when the heater comes on at power up its not instant there is about a 30 second delay like it only happens when the pi powers up.

Turricann

@Phaedrux yes it was just realized that myself.

Turricann

Thermistor attached to heater is a ATC Semitec 104GT-2 104NT-4-R025H42G

dc42

@Turricann, please state clearly which heater output and which fan output are the ones involved in this issue. I think it's heater 1 on out1, but you appear to have changed the fan configuration between the original config.g you posted and the recent one, and I can't tell whether the fan involved is on out7, out8 or out9.

Turricann

@dc42 Heater is on output1 and fan is on out7(F0)

dc42

Thanks. How have you wired the hot end heater to OUT0 and the fan to OUT7? Are the wires for the heater and fan completely separate, or have you used a common wire for both of them?

Turricann

@dc42 they have there own power and ground cables. Wired to there respective terminals, there only two pin headers so not much to go wrong there.

droftarts

@Turricann are the wires for hot end and fan bundled together? Is there any chance that connections in the wiring loom could be shorting between them? The pins between out1 and out7 are electrically isolated from each other (different MOSFET drivers and not adjacent at the MCU) so it's unlikely to be a short on the board causing this problem. Do you have a mulitmeter that you can use to check for shorts between the fan and heater wiring? Because the symptoms you describe really do point in that direction.

Turricann

@droftarts Well after some head scratching and working through my wiring you were dead right i had a short between the two ground plane's on a custom pcb which i was using as breakout board, the issue was when i was metering the hotend i removed the screws to get to the back of the PCB when i done this there is no short, but because i inadvertently connected the two ground planes to via's where the screws went threw the PCB and those screw's went into to a metal plate it caused a short.

Picked up a tool board from ooznest to replace my PCB.

Thanks For you support on this.

droftarts

@Turricann Glad you got it sorted! Those sort of issues can be a real pain to track down. Thanks for your continued support of our products!

Ian

Turricann

@droftarts there's always a possibility but they are two independent runs straight back to the board, I have checked the cable for short but not between theater and fan.
