1. What temperature did you set, before you saw it creep to 170C?
2. Are you measuring the temperature using a thermistor, thermocouple, or RTD?
If a heater gets into a fault state, you can reset it using M562 P# where # is the heater number. M0 will turn all heaters off.
UPDATE: I have just managed to reproduce heat creep on one of my printers by using a noisy thermistor channel. So now I will know when I have fixed it (or this particular cause of it).

1. Temperature starts creeping up immediately after bootup, without setting any temp. While I was testing (and temp was already creeping), I picked temp at random, just to check whether the hotend is still responsive.
2. I have Metal-J hotend from Robotdigg. They state 3950 1% Thermistor on their page. I have confirmed accuracy using multimeter, with K-type thermocouple - it was within 1C range.

Upgraded to 1.15b and the heat creep is goneQuote
dc42
I found and fixed the problem that was causing the temperature to creep up the second extruders on one of my printers. I hadn't yet tuned that heater so I was using legacy PID parameters. When legacy PID parameters was used, the code was using a D constant much larger than the one provided. Coupled with the noise in the reading from that thermistor channel, this sometimes caused the D term to override the P term and command the heater on.
I have fixed this in release 1.15b, available at [github.com].
To those of you who have been trying my recent releases, thank you for your patience.

Since updating I see a couple of things I wouldn't expect -
After homing I see the warning symbol next to the printer name and the text -
The following axes are not homed: A, B, C
Also in settings -> machine properties it says -
Z-Probe
Type:
Two Switches (4)
But I have three switches.
Any tips how to tidy this up?

- It would make sense to stop or at least pause the print if a heater fault occurs. I'll add this to the work list for the next release. Any thoughts on what would be best? I think Smoothieware responds to a heater fault by executing an emergency stop, but perhaps that is a little too drastic?

Hello all, and thanks for all your work!
I'm experiencing some issues with the PanelDue and the heated bed since upgrading to 1.15b.
1. When first powering on my printer, the PanelDue display is stuck at "starting up" until I press the reset button on the PanelDue board. Then it displays normally.
2. When adjusting the bed temperature from the PanelDue display, the temperature never changes and DWC reports a fault with the bed temperature. When I set the bed temperature via DWC, the bed does heat up, but errors after a few minutes and never reaches full temp. When I receive the bed fault, the only way to clear it is using the emergency stop, or powering off and on the printer.
These issues only started to occur after upgrading to FW dc42-1.15b on the Duet board and converting to the autotune PID (M303/M307). Before then, I was running ver. dc42-1.14 on the Duet board and using M301 to control the temperatures.
I reverted back to M301 for the bed, but the issue still occurred. I'm double checking the bed wiring now to ensure good connectivity.
A copy of my current config.g is attached.
[attachment 83183 config.g]
Any help is appreciated...
Rostock Max V2 with Diamond head
Duet 0.85 with Duex4-fw ver dc42 1.15b
PanelDue (7 inch)-fw ver 1.14
Duet Web Control ver 1.12

I had assumed that Autotune was only for the duetwifi as I'd only seen it documented in their forum .
I ran the following for auto tune (using P0.5 cancelled itself with a message to reduce P or increase S)
M303 H1 P0.4 S240
M307 H1 - reported
Heater 1 model: gain 451.5, time constant 52.9, dead time 3.8, max PWM 1.00, in use: yes, mode: PID
Setpoint change: P5.5, I0.10, D14.6
Load change: P5.5, I0.73, D14.6
Added to config.g
M307 H1 A451.5 C52.9 D3.8 B0
So far I have done one test and everything looked very smooth and no issues. I will let everything cool down and do another test later.

Thank you dc42 for your reply.
Do you have an idea why I am experiencing item #1 since upgrading to Duet FW 1.15b and Paneldue 1.14? Nothing has changed hardware-wise since first installation of Duet FW 1.11 and Paneldue 1.13 back in May. This only occurs at power on. Reboots do not reproduce the issue.

Is there any chance of adding more functionality to the webcam integration? For instance, RTSP, username/password input, etc? Right now I have to connect to it using my phone ip viewer because I have my ip cam password protected.

Should be M307Quote
14:55.21 M303
Heater 1 tuning succeeded, use M207 H1 to see result

I can only think that it is something to do with the extra 0.5 second startup delay in 1.15b. However, I don't understand why you don't get a successful connection. The initial request from PanelDue may be coming too soon for the Duet to response to it, but it should respond to the retries. Please can you try 1.15b again, with a PC connected via USB running Pronterface or another host, and send M111 S1 P3 to enable gcode debugging. Then see if you get any "aux:" gcode messages echoed.
PS - also, when PanelDue is displaying "Starting up", do the temperatures and other parameters look sensible, and can you still switch to other pages using the buttons at the bottom?
