Yes, most likely the inverter voltage sag/overload shutdown.

From the manual:
“Power Lifting mode: The Power Lifting mode is disabled by default. To enable it, press
and hold the AC power button for about 2s in Setting Mode, or turn it on directly in the
BLUETTI app. When enabled, the icon is displayed on the screen. In this mode, the
AC180 can run high drain pure resistive loads* (≤2700W) while its rated output power
remains 1800W.
Note: The Power Lifting mode is not available when charging AC180 via an AC source like
a wall outlet or generator. The AC source will bypass the inverter and supply power
directly to connected AC loads.
* Include heaters, irons or any other devices consisting of heating elements only.”
So you’d be going off-label a bit by using it on a load that isn’t purely resistive. Might work, though.
I did a little sideline once, repairing job-lots of busted inverters and selling them on. When load testing, it was rare to find one that actually put out what it said. The only ones that did were made by Waeco and Durite.

Bluetti don't mention surge though, they specifically say power lifting.
I'm not sure it's entirely square wave, but as the manual mentions, there are other limitations to using that mode.
The power bank shuts down the 240V output due to overload.

but... it'll be fine once it's rectified to DC in the printers psu (I think?)

Probably, but that choppy waveform might couple spikes through to the DC bus, and befuddle the processing. Also hard on the PSU caps and silicon bits, so might shorten its life. Hard to predict.
