I have a Plus 4. It's usable but takes a lot of work to become decent, and needs a lot of maintenance.

Is it older than March 2025?

The first year was rough, from what I've read. Mine arrived March 2025, it has taken no work to print excellently, and at about 700 hours I have lubricated it every 200 hours, and I just tightened the belts about 50 hours ago. That's it. If it's less than $100 a roll I've probably printed it. I have no complaints.

		I bought it in June 2025. From what I've gathered across Discord servers (QIDI official, QIDI unifficial and Team 7 mostly), there is a decent percentage of machines that more or less just work, as has been your experience. For the less lucky ones, it's a lifetime of tinkering. I'm on the latter cohort, unfortunately. Not to mention that out of the box you need to lock the printer in a cabinet as its printing. It used to give me headaches to be close to it for more than a couple minutes.
