MK2.5S doesn't wait for print bed to cool down before printing

[tkircher]

I preheated my Prusa to swap out some high-temperature material, then started a print job, expecting that the nozzle and bed would cool down to the specified temperatures before starting. The nozzle did cool down but the print bed was still 20C higher than the set point when the print started. This is easy to reproduce.

Sorry for the late answer.

You can use M190 R to force also the bed waiting to cool down. See https://reprap.org/wiki/G-code#M190:_Wait_for_bed_temperature_to_reach_target_temp

As an alternative, you can set in Settings -> HBed on load to [No] to prevent bed heating when operating filament load or unload operations.

In your case the high temp filament has been loaded and by choosing the Unload filament menu you will be asked which filament type want to unload. It will preheat only the hotend and unload the filament. Then when you start the print the hotend will cool down close to the target temperature while the bed will be heated.

Please consider to close this issue, when this information is sufficient.
