DeltaBot

The DeltaBot is an FDM 3D printer from Custom with a 10 x 10 x 11 mm build volume.

Calibration

• Verify the mechanical delta geometry before any software tuning.

Action: Inspect the three vertical towers, carriages, rods, joints, and effector alignment so that the tower spacing is equal and the effector can move without binding through the entire reachable envelope. Confirm that the belts or drive elements are consistently tensioned, the rods are not worn, and the carriage motion is smooth at low speed.

Common defects

• Unverified electronics and firmware stack.

The provided sources do not identify the controller board, stepper drivers, firmware family, or thermal protection configuration, so any fault analysis must remain general rather than model-specific.

Symptoms: Unknown behavior around probing, motion planning, or thermal limits; inconsistent homing; inability to reproduce settings after power cycles.

What it is used for

• Fast prototyping of thermoplastic parts.

The Delta Bot is well suited to rapid prototyping because the source explicitly emphasizes a fast motion system and the ability to print thermoplastics, with a claimed speed around 140 mm/s.
