I’ve fried my 3D printer board once because of using a cheap meter. My good meter was out of reach so I grabbed a closer dirt cheap one to measure the output of the 24V bed. Instantly shorted my board and welded the leads to the screw. Long story short, don’t cheap out on multimeters.

Sounds like you tried measuring voltage while your meter was set to measure amperage

I'm a beginner here, but I want to assume that if it was enough to weld it, the cheap meter wasn't the problem.

What exactly happened there, and why do you think it wouldn't happen with a more expensive meter?

My fluke has a fuse on the ammeter.

Yes, unfused 10A range would have been my guess, but if device under test doesn't have short-circuit protection, it might as well die during the few tens of milliseconds that the fuse needs to heat up and blow, as well as a user error to be measuring voltage with switch in current measurement position.
