How to disable the auto switch off
I want to dry my drying sacks in the printer. Normally on a sunny day with endless pv-power I am running the heat bed on 60° C for many hours. Since the new firmware the printer keeps switching off after 30 minutes. Please add an option in the menu to disable the automatic switch off.
How can I keep the printer running with set chamber temperature?
RE: How to disable the auto switch off
Create a file (for example "drying.gcode") and insert the lines into it:
M140 Sxx; set bed temp, after S is the desired temp M106 P3 S1; set the minimum speed of the rear fans G4 Sxxxx; wait, after the letter S is the drying time in seconds M140 S0; turn off the bed M107; turn off the fan M84 X Y E; turn off the motors
Save the file and upload it to the printer like any other print file and "print". If the printer issues any error messages when starting the "print", ignore them. The file must be created using Notepad, or a similar editor, not Word. Turning on the fan is necessary to remove humid air.
Caution! The printer must be checked often!
