Hello, Vitor, hi, everybody.
The bug reproduces only if Enclosure plugin (EP) is enabled. If EP is disabled the bug never happens.
** The bug **
I have inserted @pause command into the G-code to change filament during print. The print pauses at the correct time/point. Changing filament takes up to 2 minutes. Sometimes printer correctly waits those 2 minutes and resumes printing only after "resume" button is pushed in OctoPrint interface. But almost every other time printer resumes to print about 40 seconds after the pause started WITHOUT "resume" button to be pushed (even without pushed accidentally).
I do not use filament sensor in Enclosure plugin. I use DS18B20 temp sensor, enclosure ventilation fan, heater and led control.
To Reproduce
Take any G-code.
Insert @pause command at the beginning of any layer.
Print until printer pauses.
Wait more than two minutes. With a chance of ~50% printer will resume printing without user to push the resume button.
Expected behavior
Printer resumes only after user pushes the "resume" button in OctoPrint interface.

My OctoPrint ver. 1.3.9, Enclosure plugin v.4.12, printer firmware Repetier 1.0.3, no Klipper
Otherwise Enclosure plugin works fine: it monitors enclosure temp, switches heater and ventilation according to temperature, switches LEDs. It is the most useful (and loved by me) Octoprint plugin.
Thank you.
In the meantime I have also tried to use M600 command in G-code. In one try out of three the pause was also prematurely interrupted and print resumed before I pushed the encoder. It happened when enclosure plugin was enabled. When enclosure plugin was disabled pausing with M600 and resuming worked as expected (printing resumed only after I pushed the encoder). This is additional argument that enclosure plugin makes the printer to resume during the pause.
Do you have any other plugin installed?
I have no idea why this would happen, I only have marling printers, is the pause command supposed to be handled by octoprint or is it a repetier thing?
I'm going to do some research.
Hello, Vitor.
I do have several other plugins installed. If needed I can give the list of them later. But Enclosure plugin seem to be the only involved: when I disable it and leave other plugins active the bug is not reproduced. When I enable Enclosure plugin the bug re-appears.
The @Pause command is handled by Octorpint. When I mention "Pause" and "resume" buttons I mean the buttons of Octoprint interface, not Repetier interface. Repetier is only firmware, it does what Octoprint tells it to do.
It seems like Enclosure plugin "doesn't know" that print is paused and while during the pause it still monitors enclosure temp and sends signals to heater and ventilation (cooler) those signals trigger Octoprint to resume the print. Sorry but I did not notice if premature resume was contemporal with heater or cooler turning on or off. I think this should be investigated. Or as test you may try to disable temp monitoring or sending those signal during execution of @Pause command.
Thank you for investigating in this bug.
I wish you wonderful trip to New Zealand (what I also dream to do some day)!
We can concur that this happens.
We did some tests and the print resumes when our dehumidifier is switched off because the humidity gets below the trip value. (the off to on state does not resume the print)
The same goes for the temperature control.
All other in and outputs of the enclosure plugin have no effect to the pause.
All other plugins also have no effect to the pause
Vitor, have you got any news on this issue?
Thank you.
Have you found any workaround?
except disabling the Temperature Control and Hum Control?
