Hello, strange thing happend today. I changed the material for the second extruder to ABS.
So, first is PLA, second is ABS. I want only to print with the second.
First try was to just set all objects to the second extruder ... slice ... and see, some lines are done with the first extruder! WTF. Its printing, but a few lines wrong material!
Second try was to deactivate the first extruder in Cura ... slice ... all lines are for second extruder. But (BUT) if i try to print, it keeps the cold extruder active and is happy extruding with the second extruder in parking position (blocked nuzzle).
I really have no clue for what i paid the money!? For having a 3D printer or for getting a bunch of useless CRAP.
I dont talk about material loading or unloading.
Its about printing.
I have my model setup to print only from E1. So, the print, the support and the brim is manually set to E1.
The printer heats correctly E1. But even if i select before E1, the printer just switch to E0. After bed leveling the printer have E0 down but extruding E1 so that all the material runs down from its parking position.
HOWEVER: if i keep the brim at E0 (both hotends are heated up correctly) it prints the brim with E0 and switch then correct to E1 and finish the job correctly (except the stupid Halt() on the bed overheating issue, but that is another case) .
Thanks for the info for unloading ABS. But, as i told, its not my problem for now.
