With the Bluer Plus, Two Trees adds to their offering a large format cartesian 3D printer boasting a few interesting hardware features like 0.9-degree stepper motors, BMG extruder, auto-leveling v-slot wheels and a PEI sheet out of the box. I was skeptic for testing this printer because I suspected quality…

Do you know if the 2022 version you received still has the 0.9mm stepper motors? I’ve heard mixed reports on that.

So I have a conundrum - I ordered an upgraded BLU-5 from TwoTrees, but they shipped me a NOS 2020 Bluer plus. So here’s the dilemma - do I return the old one and get a new one? as I understand it:

OLD: 0.9 stepper motors, 4 drivers, old firmware, 1 motherboard fan, hotbed strain relief

NEW: 1.8 stepper motors, 5 drivers (1 unused), newer firmware, no strain relief

I’m almost thinking to keep the old one, but looking for input from those who know more.
