Please reduce the PCBlend temp for bed leveling to avoid nozzle cleaning failures

Open m-cas opened this issue 10 months ago • 0 comments

Unlike PETG and PLA, every single time I try to print with PC Blend the nozzle cleaning fails. The reason is that the nozzle temp is so high that a constant stream of material oozes through it and prevents a successful cleaning.

Reducing the temperature of PC blend by 50 degrees instead of the currently implemented 25 makes the problem go away in my case.

I am using an MK4 (kit) inside a Prusa Enclosure.

I changed these two lines in the slicer printer setting and substituted -50 instead of the default -25:

M104 T0 S{((filament_notes[0]=~/.HT_MBL10./) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.PET./) ? 175 : 170)} ; set extruder temp for bed leveling M109 T0 R{((filament_notes[0]=~/.HT_MBL10./) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.PET./) ? 175 : 170)} ; wait for temp
