¶ Applicable models of printers
X1C
¶ Core XY Movement System
The Core XY Movement System is installed on the top of the printer to allow the toolhead to move in the X/Y direction.
- This component is difficult to replace, so it is recommended to read this replacement guide carefully before replacing it.
- There are a lot of screws involved in the replacement of this component, so it is recommended to prepare some small boxes in advance for storing the different screws.
¶ When to use?
- The idler pulley makes noise or is damaged.
- The core XY movement system is bent and deformed.
- The Y-axis linear bearing is damaged.
- The Y-axis linear rod is damaged.
¶ Safety Warning
IMPORTANT!
It's crucial to power off the printer before conducting any maintenance work, including work on the printer's electronics and tool head wires. Performing tasks with the printer on can result in a short circuit, leading to electronic damage and safety hazards.
During maintenance or troubleshooting, you may need to disassemble parts, including the hotend. This exposes wires and electrical components that could short circuit if they contact each other, other metal, or electronic components while the printer is still on. This can result in damage to the printer's electronics and additional issues.
Therefore, it's crucial to turn off the printer and disconnect it from the power source before conducting any maintenance. This prevents short circuits or damage to the printer's electronics, ensuring safe and effective maintenance. For any concerns or questions about following this guide, open a new ticket in our Support Page and we will do our best to respond promptly and provide the assistance you need.
