Feature request or advice: Auto-refill for 2 x AMS HT units with H2d

Bambu Lab H2 Series Bambu Lab H2D
1

Set up: H2D printer with 2 AMS HT units, one connected to right printhead, the other to the left. Printing with one color of filament only, same filament type & manufacturer. Printing in common print area, i.e. the area that both printheads can reach.

Request: Would like to load both AMS HT units with the same filament, and have the printer automatically switch to the second filament spool when the first becomes empty.

AFAICS, there’s no way to do this. All of the “auto refill” functions only work with one 4-spool AMS (or a combination of AMS units) connected to one printhead.

This should be possible since the printheads have the same functionality in the common print zone.

If there’s a way to do this, kindly reply!

If not, Bambu, please consider this a feature request. It would be a huge leap forward in functionality for those of use who only have 2 AMS HT units.

You’ll need to elaborate on how you expect the slicer to account for the separate tool-head paths required. Why not simply connect those two AMS HT units to the same tool head instead?

I run two AMS HTs on my left tool head, two on my right, and two AMS 2 Pros on each side, and everything works flawlessly. So I’m struggling to see what you’re trying to achieve that isn’t already possible—and why.

Sorry it’s not possible with current bambu hardware, it’s not as simple as “if this then that”, which we all hoped it would be…

He wants the left hotend to continue right hotend’s task if right hotend runs out of filament. Which isn’t possible by the way gcode works.
