Adjusting the Motion Belts¶

Proper belt tension is essential for your machine to execute designs with precision. This guide provides tips on how to tension the belts easily and how to identify the ideal tension for your Due Flow.

The Importance of Motion Belts¶

Belts are responsible for transmitting movement from the motors to the carriages. If they are not correctly calibrated, the quality of your cuts and engravings will be compromised.

Ideal Belt Tension¶

The tension of the belts should be similar to a guitar string:

Too Loose: The belt teeth may "skip" on the motor gear, resulting in distorted designs and loss of precision.
Too Tight: The movement becomes too heavy, overworking the motors. Over time, this can cause the motor drivers to fail.

Testing the Precision¶

The best way to verify belt tension is by cutting a circle. Run a circle in "Outline" mode with a high speed (80 or more) to test the machine's limits.

Required Tools¶

To adjust the tension, you will need: * Nylon cable ties (zip ties) to secure the belt. * Needle-nose pliers to pull the belt to the correct tension.

How to Tension the Belts¶

1. X-Axis Belt¶

If your machine has a central carriage cover, you will need to remove it first to access the belt mechanism.

2. Y-Axis Belts¶

The Y-axis belts run along the sides of the machine. Ensure both the left and right belts have the same tension to avoid "racking" or misaligned movements.

Final Check

After making adjustments, repeat the circle test at high speed. If the circle is perfectly round and the lines meet at the starting point, your belts are correctly tensioned.
