Hello,
What BBL A1 spare parts do you recommend having at home? Which components are more prone to being replaced?
Thank you.

Too soon?

Buildplate, filemant cutters, nozzle wiper, 1 extruder gear and an extra nozzle in the size you use most. Or at least that’s what I tend to keep in stock. The rest is incidental, but these parts are “wear” parts.

How do you know when it’s time to change out the extruder gear?
You’ll know, want exact indications? Check google. And besides it’s a plastic gear, I much rather keep a part on stock that costs me next to nothing than wait days or weeks for it to arrive when I most need it (plus ordering all stuff I might need in bulk saves on shipping cost)
Anything that’s a consumable: silicon socks, extra build plates, nozzle wipers, replacement filament cutters. You know you’ll need it eventually. Therefore, get it now so that it will be ready to deploy and you don’t miss a beat.
