Blocks Pro S30

The Blocks Pro S30 is an FDM 3D printer from Blocks with a 300 x 310 x 300 mm build volume.

Specifications

Hello Krasi, and welcome to this detailed architectural review of the Blocks Pro S30. This machine represents Blocks Technology’s initial entrance into the professional and industrial additive manufacturing market. Engineered for factory floor environments, the Pro S30 features an expanded build volume, a heavy-duty sheet steel chassis, and high-precision linear guide rails. Let's break down its verified engineering specifications:

• Hotend: The Pro S30 is equipped with a high-performance all-metal hotend capable of reaching operating temperatures up to 300°C.

Calibration

Tuning the Blocks Pro S30 for geometric precision requires aligning its mechanical frame with the software compensation systems. Follow these 8 calibration steps:

• Dual Z-axis Alignment (Mechanical Leveling):
• Description: Since the Z-axis is driven by two independent motors on a shared driver or separate drivers without auto-alignment, the bed can lose horizontal alignment when powered down. Turn off the printer.

Common defects

• Hardware defects and mechanical weaknesses
• Z-motor Desynchronization: Because the dual Z-motors run on a shared driver or separate drivers without auto-alignment, mechanical resistance on one side of the bed (due to lack of lubrication or rail tension) will cause one motor to lag. This tilts the bed, resulting in layer height variances. Solution: Manually square the bed gantry and apply grease to the Z-axis guide shafts.

What it is used for

Recommended:

• Manufacturing Jigs and Fixtures: The rigid steel chassis and linear guide rails provide high dimensional accuracy for assembly templates.
• Large-Format PETG and PLA Parts: The 300 x 310 x 300 mm build volume is suitable for printing large enclosures and brackets without sectioning.
