…Which it should have friggin’ come with from the start. I still have no idea what Qidi was smoking providing a plate textured the same on both sides, especially when their previous printers already came with a dual-sided plate. At least now I can make parts that are actually flat on the bottom.

The textured plate was kind of cool for doing large parts with visible flat surfaces, like box lids. But it kind of sucks for doing small mechanical parts.

Kapton sheet optional, but I’d rather replace a 30 cent piece of tape rather than a $48 build plate due to the surface wearing out over time. The massive sheets I used for my old printer (and trimmed down) are almost big enough for the X-Max 3’s plate. I think you’d have to try quite hard to print in the last 10mm around the edges anyhow.

I will say this about the whizz-bang side firing build plate fan in these new 3rd gen Qidi printers… It’s completely unnecessary, at least with regular PLA. Less than useless. It cools the plate too much, to the point that it can’t maintain its surface temperature and your parts will curl and lift off the plate on the side where the fan is. I just disabled it in the slicer. Even printing at pretty high speed – IIRC the default for regular PLA is 250 mm/sec – I haven’t found any need for the extra cooling, not even with bridges and stuff. Maybe it’s more useful when you’re printing with Qidi’s “Rapido” PLA, which I’m sure as hell not paying for.

Also.

Heh heh heh.

    I personally don’t mind textured pei for small mechanical parts but the roughness and depth of the texture can vary wildly.

    But take a look at g10 fr4 sheets, they work perfectly for pla/abs/tpu and have a flat finish. A 330x330x3mm plate should only run you about $25 less if you can source it locally.

    Edit: the side cooling fan is only useful for speed benchies or doing a plate full of parts with overhangs where the fan on the toolhead doesn’t spend enough time in one place to cool effectively. The side fan might also be placed too low, impacting bed temps more than it ideally does. If you plan on using it more I would recommend doing the bed pid tune with the fan at printing speeds.
