In this guide, we will show how to replace the heatbed nozzle wipers on the A1 mini and install a new set.
This guide is intended for use if there is visible damage to the filament wipers. Over time, the silicone wiper bristles can become damaged, and the metallic wiper may wear out or become bent.
Common issues that may indicate the need for replacement of the A1 nozzle wipers include:
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.
