Two Trees Bluer

The Two Trees Bluer is an FDM 3D printer from Two with a 235 x 235 x 280 mm build volume.

Calibration

• Verify the printer’s mechanical baseline before any software tuning.

Start by powering off the machine and checking the X/Y belt tension, wheel smoothness, gantry square, and Z synchronization. The source material highlights adjustable X/Y belt tensioners and a dual-Z arrangement, which means the printer can drift mechanically if it was shipped, transported, or assembled with uneven tension .

Common defects

• Open-frame thermal instability with ABS and similar materials.

Symptoms: Corner lifting, layer splitting, inconsistent dimensional accuracy on tall parts, and visible warping on large footprints.

Cause: The printer is open-frame rather than enclosed, while the sources explicitly position it as suitable for ABS-type materials via a heated bed rather than a heated chamber .
