Heater Will not turn off once started.
-
@Phaedrux if I do that I would expect the heater to be off.. the issue seems to be once its on it will not turn off.
-
@Turricann
pheadrux wants to test if your mosfet is blown. that is a quick way to test it. -
What i have done to prove its not hardware is heated the hotend to 200 degrees then powered down and removed the PI I/O cable, when powered back up the heater stayed off.
I then Powered down again and refitted the I/O cable, when powered back up and the temp was @145 degrees fan came on and heater came on although temps were set to 0 and status set to Off.
It seems to be when the hotend fan is on the heater is running ... so if temp goes above 45 degrees fan turns on and heater will not turn off.
If thermostatic control is turned off the fan then the heater comes on when the board is powered ( actual timing is when Pi is booted).

@Turricann I am slightly confused by the thread. is the 6HC running in stand alone mode or with an attached SBC?
In either case what version of firmware are you running? Please try upgrading to 3.2b4.1
I have noticed one off thing with your config:
M106 P1 S1 H T45H should have a heater number after it or be set to -1 (and i assume it is not intended for it to be off) not sure how you have the fans connected as you only have 1 hotend heater configured but if you want these fans to be based on the heater then this should be H1
-
@T3P3Tony The setup is a duet 3 6HC running with a Pi , the pi has its own 5a supply. I am upgrading the firmware and the software to the latest as we speak but originally I was running RRF 3.1.1.
As for the fans currently I have 3 fans on out7,8,9 but nomatter which header I use the same issue occurred.
Yes m103 its set to H1 must of captured that while making changes.
-
Can you also send M98 P"config.g" in the console and report the results?
-
not any more since updating to RRF 3 beta 4 i am getting DCS failed to connect to duet 3

Can you start from a freshly downloaded version of DuetPi and then update from there with sudo apt update sudo apt upgrade?
-
Still the same DCS is not started. RRF 3.1.1 --> board has 3.2 beta 4
-
Are you saying you started with a fresh image and updated, then added the unstable branch and updated again?
-
No the image on the Pi is the one from the link but just checked,
pi@duet3:~ $ sudo apt list duetcontrolserver -a

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.listhttps://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Software_Installation

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.
-
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 supplyOut0 - 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 = Z3Thats 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?
-
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.
-
It looks like your config was pasted twice maybe in your last post?
-
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.
-
@Phaedrux yes it was just realized that myself.
