Don't quote me but I took it as: The bed is On or Off, pid or bang bang aside the bed is on or off. While the tool, could be any tool and the wording Active is the right choice as it's the Active tool. Know clue, just what I put together from looking at things.

Thank you good sir, that rectified my problem.

Hello all, I have a question about the Auto Heating function.

Board: Duet 2 WiFi (2WiFi) v1.02
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3 (2021-06-15)
Duet WiFi Server Version: 1.26

I'm not sure if it's DWC or the some firmware setting but when I Pick from the drop down, or enter a temp and hit Enter my bed will begin to heat up on it's own. If I pick a temp for my extruder, or enter one manually it remains off, I have to click on the extruder to activate the heater. Is this a safety feature, bad config.g, or a bug? I would like my extruder to also begin heating up after selecting or entering a temperature manually.

Thank you.

@abeardeditalian said in Extruding while PID tune, Bug? Dwifi1.02 FW3.3:

30w 12v heater

I played around with it some more since making this post, I didn't realize I could manually tune my PID while printing. These are my new settings:

"M307 H1 R0.50 C100 D3.0 S1.00 V11.9 B0 I0"

I'm not really sure what all I did, the documentation on what everything does is pretty vague and only a few posts have I found things described.

Example from another post "The heater tuning doesn't always establish the value of the dead time (D parameter in the M307 command) very accurately. If D is set too low then the temperature will oscillate; so if you see the temperature oscillating regularly even when not printing, then try increasing D, initially by about 50%. If D is set too high then the PID will be slow to respond to external changes, for example the print cooling fan turning on."

I also found this for the depreciated A value but I would like to think R functions the same. "If the temperature overshoots, increase the gain (A parameter). If it undershoots, reduce the A parameter."

If someone could provide a little more verb-age on what the C and R rates do that'd be really appreciated, Thank you.

Hello all,

Duet Wifi 1.02
FW 3.3
Titen aero
v1 Volcano w/ sock 1.0mm nozzle
30w 12v heater

I'm currently trying to tune my volcano, autotune works great but when I start to print with high volume the hotend is cooling down causing a heater fault.

I tried to extruding plastic while running autotune and it seems to be breaking the autotune process, I wait for it to get to temp 265c. Send "T0 G1 E250 F200" and the command sends but while watching DWC the Heater 1 temp begins to drop like I stopped the process. Also when the first command is sent nothing is actually extruded but the temp begins to drop, if i send the command a second time it will begin to extrude but the heater isn't heating.

M307 H1 R1.378 C262.729:262.729 D7.25 S1.00 V11.9 B0 I0

Here's my current PID from my last autotune, I've tried doubling my C and D values but it'll overshoot before printing to 266, and when printing the first layer it'll drop to 263 and begin to recover/hold. On the second layer it drops all the way to 249 and the print aborts .

Am I missing something, how can I tune my hotend for the volume I'm trying to print with?
