I have a problem by printing the support (see picture attached). I seems like if no material went out of the extruder...
The extruder and the heater are brand new, but this doesn't change anything to the problem. The Z-ABS cold grey spool is also brand new, out of box. I've cleaned the gear of the "filament feeder".
I don't know where it comes from. Any help would be very welcome!!
I was in medium infill with support normal, I tried infill high with support light and the problem was no more visible. But it is strange with a new extruder…
