Lotmaxx Shark

The Lotmaxx Shark is an FDM 3D printer from Lotmaxx with a 110 x 110 x 150 mm build volume.

Calibration

• Bed Leveling with BLTouch

Step: Begin by ensuring the BLTouch sensor is properly mounted and calibrated. Power on the printer and navigate to the "Leveling" menu on the touchscreen. Select "Auto Leveling" and initiate the probing process. The printer will move the BLTouch to nine predefined points on the bed, measuring the distance between the nozzle and the surface. If the bed is uneven, the firmware will generate a mesh map to compensate for height variations.

Common defects

• Hardware defects and mechanical weaknesses

Symptom: Users have reported occasional belt slippage on the Y-axis, leading to inconsistent layer heights.

Cause: The Y-axis belt is driven by a single stepper motor, which can struggle to maintain tension during high-speed printing.

Solution: Replace the single motor with a dual-motor setup or add a belt tensioner to the Y-axis.

What it is used for

The Lotmaxx Shark excels in scenarios requiring medium to large print volumes with moderate precision. Its build volume of 300 x 300 x 400 mm makes it ideal for prototyping, hobbyist projects, and small-batch manufacturing. The printer is particularly well-suited for materials like PLA, PETG, and TPU, which benefit from its heated bed and stable thermal environment.
