Custom Length X-Axis GT2 Belt
For many 3D printers, the XChange Master Assembly requires a slight adjustment to the factory x-axis belt length. This is because the tabs that secure the belts on the hot end carriages of most machines varies by manufacturer and model.
If needed, you can measure your x-axis, and use this calculator to determine the correct length for your XChange compatible belt. *Note that you must download the calculator spreadsheet and open it in Excel or Google Sheets (free for Google account holders).
