Anycubic i3 Mega / Mega-S

Now that you've read how to do the Atomic the traditional way here's an alternative method that you can do as well. We like to do this every time we change material. Instead of removing the bowden tube you can actually just push and pull filament at the feeder end. As long as the feeder motor is powered down (easily accomplished by power cycling the machine) it's not difficult to manually push filament into the hot end or pull it out.
So what we do when changing filament is to heat the print head up to printing temperature. Then push filament manually until it starts coming out of the nozzle. Then lower the temperature and finally pull the filament out with a quick tug once the temperature reaches ~85-90C. When you now insert the new material you wont have to flush the old colour out, you'll get the new colour immediately and you will have cleaned the nozzle at the same time.
You should snip off the cone shaped tip of the old filament as it will be slightly thicker and can be difficult to load properly.

Ce se poate face e sa se genereze o masca care sa contina reperele de gaurire a unui circuit imprimat.

Sugestia cu printatul traseelor urmata de vopsire se poate aplica doar la PCB-urile cu trasee extrem de simple, care nu formeaza insule.

Mega si Mega S sunt practic identice - nici nu cred ca mai fac astia de la Anycubic (doar) Mega. La un moment dat au montat un extruder o idee mai performant si ca sa marcheze diferența i-au zis Mega S.
