Module 2 — Rules summary
Module 2 · Rules summary
A short list of the rules in Module 2, to look back at. It is a reminder, not a replacement for the lessons: the quiz covers the whole module.
Materials
Each printer group has its own allow-list. Print only what's on that printer's list.
Never allowed: PVC, POM/acetal, water-soluble filament (PVA, BVOH and the like), any flexible filament, any glow-in-the-dark filament, and unidentified filament.
New material? Ask in Slack. You may print it once the developers have tested it and it's on the wiki.
Silk PLA: lower-row X2Ds and H2S. On the upper row, only Bambu PLA Silk+.
Filled filament (carbon fibre, glass fibre, wood, stone, metal): lower row and H2S only, and only if the base material is allowed there.
Sand carbon-fibre and glass-fibre parts wet, in a shallow tray of water.
Support and glue
Support material: breakaway support matched to the model material, or PLA and PETG supporting each other. Upper row: only Bambu Support for PLA.
AMS HT: nothing that Bambu's X2D compatibility guide rates "highly not recommended" or "unavailable" for the right nozzle.
Glue: Bambu Liquid Glue, on Textured PEI only. PETG always gets it.
Printers and AMS
Use an H2S only when the job needs its size.
Spools go in the AMS just before your print and come out after it. Never use an AMS just to dry filament.
Dryers
Prefer the S4 for PLA, PETG and their support filaments, and the Royal dryer for anything hotter. Anything over 70 °C goes in the Royal dryer.
If one dryer is busy, use the other at your filament's temperature.
First come, first served. You may add spools to a cycle that is already running, but don't change its settings while it runs.
Nozzles
Nozzle changes: H2S only, between 0.4 mm and 0.8 mm high-flow, and only if you know how.
Afterwards: set the new size on the screen and on the indicator, re-sync Bambu Studio, and put the old hotend in the drawer under the left H2S.
Swap back to 0.4 mm when your print is finished.
Faults
Clogs: the needle method, at about 10 °C above printing temperature, is fine. No open flame.
Screws out or wires off? Ask in Slack and wait for a room developer or board member to reply.
Everything in Module 1 still applies: nametag, one printer at a time, the whole first layer, bed levelling never off, moulded plastic spools, filament path left alone, plastic scrapers, clean up, LAN only.
