Blob of filament at the start of the intro line in single MMU2S prints.
In a single mmu print, the printer extrudes a blob of filament at the beginning of the intro line, them the extruder proceeds to print the intro line.
The blob usually gets stuck to the nozzle, it can get sometimes wiped on the intro line, but usually it stays during the print and then randomly detaches making an ugly blob of filament.
To prevent this, i wait for the printer to make the blob and then use a piece of filament to take it manually.
I could change the GCode but i don't know much about it.
If someone knows the solution please let me know.
