Product Description

The original QIDI Max4 Print-head Cable is a replacement print-head connection cable designed exclusively for the large-format 3D printer QIDI Max4. This cable ensures power and signal transmission between the print head and the printer mainboard and is designed to withstand high printing speeds of up to 800 mm/s and acceleration up to 30,000 mm/s² in the Max4 CoreXY mechanics.

Using an original cable from the manufacturer is crucial for reliable hotend heating, precise extruder motor control, and sensor reading in the print head. A damaged or fatigued cable can cause heating failures, sensing errors, or accidental printer resets – timely replacement significantly reduces the risk of failed prints and protects the electronics.

Main Features

• Original QIDI Tech replacement part – full compatibility with the QIDI Max4 3D printer.
• Cable between print head and printer – transmits power, motor signals, fans, and sensors.
• Designed for the high-speed CoreXY system of the Max4 (up to 800 mm/s, 30,000 mm/s²).
• Flexible design – resistant to repeated bending during print head movement.
• Color-coded connector on the print head side for easy orientation during assembly.
• Simple replacement – replacement can be done without special tools, just unplug the original cable and plug in the new one.
• Suitable as a spare part – minimizes printer downtime in case of unexpected cable damage.

Use and Compatibility

• Compatible printer models:
  • QIDI Max4 (all versions specified by the manufacturer for this cable)

The cable is intended exclusively for the QIDI Max4 printer. For other models (Q1-Pro, Plus4, Q2, etc.), there are separate print-head cable variants – it is necessary to choose the correct version according to the printer model.

Installation

1. Turn off the printer and disconnect the power cable.
2. Carefully remove the cover in the electronics / print head area according to the printer manufacturer's instructions.
3. Disconnect the original cable from the connectors on the print head and the mainboard.
4. Note or photograph the routing of the original cable so that the new cable follows the same path (without sharp bends or tension).
5. Plug the new cable into the corresponding connectors – pay attention to the correct orientation of the connector locks.
6. Check that the cable is not pinched anywhere and can move freely throughout the entire workspace.
7. Close the covers, plug in the power, and perform a short test of print head movement and heating.

Who is the product for

• Users of the QIDI Max4 3D printer who have experienced:
  • hotend or fan heating failures,
  • sensor error messages in the print head,
  • unstable behavior during print head movement.
• Service technicians and operators of multiple printers who want to keep critical spare parts in stock to minimize downtime.

Advantages of using the original cable

• Guaranteed compatibility with QIDI Max4 electronics and firmware.
• Reduced risk of overheating or connector damage thanks to correctly dimensioned wire cross-sections.
• Safer operation – quality insulation and reliable connectors reduce the risk of short circuits.
• Maximum preservation of print quality and speed for which the Max4 is designed.

Package Content

• 1× QIDI Max4 Print-head Cable (complete print head cable for QIDI Max4)

Recommendation: For very intensive operation or printing at high speeds, it is advisable to have at least one spare print-head cable in stock. Replacement is quick and prevents long printer downtimes in case of damage to the original cable.
