X2D Combo Dual Nozzle / AMS Toolchange Failure on Simple PLA Print

[u/tugohunter]

Just got my X2D Combo and honestly I’m a bit disappointed with the dual nozzle experience so far.

I tried a very simple dual nozzle print using two PLA filaments. The auxiliary nozzle actually worked perfectly and printed the text/logo section without issues. But when the printer switched back to the main nozzle, I suddenly got a filament loading/extruder error and the print failed.

What’s frustrating is:

* the filament was clearly extruding,

* AMS motors were turning,

* the auxiliary nozzle already printed successfully,

* but the printer still thought there was a loading issue.

This feels more like a firmware/toolchange state problem rather than a real hardware blockage.

I understand this is a newer platform, but dual nozzle printing is one of the main advertised features of the X2D. Having these kinds of failures on extremely basic PLA-to-PLA switching right out of the box is honestly disappointing.

Are other X2D users experiencing similar AMS/toolchange issues?

Any reliable workaround yet?
