When B2 runs out there are three “continuation” scenarios that I can think of:
- An identical filament (type and colour) has been inserted into another slot with which to continue
- A compatible filament (type) has been inserted into another slot with which to continue
- No identical or compatible filaments have been inserted into empty slots
I’m still pondering through whether 1 and 2 match, or are compared with only the original spool with which printing started (A1), or with any of the successive spools (A4, B2), or even with the empty slot that has had a spool inserted after printing started.
If A1 and A4 were replaced/refilled when printing with B2, does the circular sequence continue, or does printing continue with the “most” compatible spool available - a matching type and colour would trump a matching type with different colour.
There are many permutations.
Ideally, it would be most helpful if the refill sequence could be shuffled before printing starts, and again as spools are replaced while printing continues, or empty slots are filled - on the console on an X1 would be just fine, or on the mobile or desktop app for any other printer/AMS combo.
When BBL spools with RFID tags are used, more of this could be automated/simplified. That would be great for those who almost exclusively use BBL filament.
There needs to be more real-time filament swapping/refilling capability added.
