I Did print those new version files. It doesn't work with spool less laywood rolls
I have checkes everythiong and I have printed all parts and tested them. For other spools the design works really noche, but for lywood rolls... forget it. The problem is the orientation: there is no way of pulling from the filament in an horizontal way. The filament just stretchs and adjust around the spool. When the extruder pulls from the filamet sometimes the filament is pulled, sometimes the filament starts to adjust around the spoll and sometimes it adjusts itselsf so hard that it breaks (laywood is very sensitive to this. So people: great design but it doesnt work with spool less laywood filaments.
