I’ve been pretty happy with it. PLA is pretty spot on, and I need to scale ABS by 100.4% for large parts to cover shrinkage but I do that with other printers, too.

Is it as dimensionally accurate as the Voron V0.2 above it in that picture? No. But is it really close? Yes. If your tollerences are a mm, you’ll be fine. I’d only worry if the tolerences were less thsn say .2-.4 mm. Just remember some materials shrink as they cool, no matter what printer you use, so calibration is key for them.

Given you’re thinking chamber heater, you probably already know how to handle that, though.
