X-Max 3

The X-Max 3 is an FDM 3D printer from Qidi with a 325 x 325 x 315 mm build volume.

Specifications

Hotend: Features a high-flow direct drive extruder with a maximum printing temperature of 350°C . It comes with two hotends out of the box: a copper alloy nozzle for standard materials and a hardened steel nozzle for abrasive materials .

Bed: The heated print bed reaches a maximum temperature of 120°C [2, 5]. It features a double-sided flexible magnetic PEI plate for strong adhesion and easy print removal [2, 6, 7].

Chamber: Equipped with independent chamber heating that reaches up to 65°C, which is ideal for preventing warping when printing engineering materials like ABS and ASA [2, 8].

Calibration

1. Bed Leveling (Manual & Auto)

• Step: Preheat the build bed to 60°C . First, perform a Screw Tilt Adjustment by loosening or tightening the screws underneath the PEI plate to manually tram the bed and minimize variance [2, 3]. Then, run the printer's 16-point automatic bed leveling routine via the touchscreen [4, 5].
• Expected Outcome: A consistently trammed bed with a mesh matrix variance ideally under 0.2mm to 0.4mm .

Common defects

Z-Offset and Bed Leveling Failures

• Symptom: The nozzle crashes into the build plate during bed leveling or Z-offset calibration .

Cause: The inductive sensor is mounted too high or the nozzle is too low . Additionally, calibrating the Z-offset via the Fluidd web interface corrupts the Qidi system's saved values, or the user forgot to place the removable magnetic build plate back onto the bed .
