[BUG] Robin Nano v3.1 datatransfer by wifi => No temp-crontrol during transfer #338
Description
Did you test the latest bugfix-2.0.x code?
No
Bug Description
If I preheat my bed and nozzle before I initiate a wifi datatransfer, Marlin stops controlling the temperature during filetransfer.
If you transfer bigger files (which might take long, since the wifi transfer is only 100km/s!) the temperature might be coarse off the determined temperature.
On the headbed this is no big deal, since this usually has not enough power to overheat. But for the nozzle the printer reports an overtemperature warning once the filetransfer if finished and starts peeping (if you have the firmware with enabled beeper).
Bug Timeline
Figured it out during the last days...
Expected behavior
Even through filetransfer using wifi the temperature control should have a watchdogtimer to check it regular!
Actual behavior
If filetransfer starts within a heating period of the PID control, it might overheat.
Steps to Reproduce
Set your printer to preheat (I usually do this manually by choosing a temperature that is slightly higher for my headbet than the actual print - i.e. preheat on 60°C, but need 55°C to start print).
Then start transfering a bigger file using wifi.
Please do not test this on the nozzle until it is fixed. It might break your nozzle or burn your filament.
