Description
When you enable MPCTEMP and ADVANCED_PAUSE_FEATURE and then do filament load (M701) on a bowden type printer the temperature can go way above setpoint due to MPC's filament_heat_capacity_permm compensation. As the filament is quickly loaded through the bowden MPC thinks a huge volume of filament is being extruded through the nozzle and adjusts power to max. Depending on particulat heater power this can be just 10C jump or much higher for high-powered heaters.
This commit fixed the problem by disabling the compensation for the duration of filament load.
Requirements
Enabled MPCTEMP and ADVANCED_PAUSE_FEATURE. Printer with long bowden.
Benefits
Problem is fixed.
Configurations
