as i said to another reply, it is a material issue.
That does not match my experience. The printer I have has had parts break with light use, and a really poorly engineered z-axis homing which results in wildly inconsistent zero heights and a very high print failure rate.
I've owned or used probably every major (and some minor) printer released in the last 8 years and for most people Bambu really will just be "plug and play" (and even if something goes wrong they'll hold hands as much as needed)
