¶ Heatbed Surface Magnet
The heatbed soft magnetic is a magnetic soft rubber attached to the surface of the heatbed aluminum base plate. Its main function is to ensure good magnetic attraction for the build plate. On our P1 series printers, due to some structural differences, there are two versions of Heatbed Surface Magnet. One is with holes to avoid the leveling screws, the other one is without holes.
The X1 series printers use the one without holes.

If your printer needs to replace the surface magnet, please order it based on the actual version to avoid errors.
If you have bought the wrong version, you can still replace it. You only need to make holes in the corresponding positions after attaching the surface magnet to fully expose the screws below.
¶ When to replace
1. The surface magnet is bubbling, and there are obvious bulges after the build plate is placed;
2. The surface magnet is damaged and turned upward, and there are obvious bulges after the build plate is placed;
3. The surface magnet is too weak to attract the build plate.
Warm reminder: Some scratches, dents, or even small-scale damage on the surface magnet will not affect the printing function and does not need to be replaced as long as the build plate is not lifted up.

¶ Safety Warning
IMPORTANT!
It's crucial to power off the printer before performing any maintenance work on the printer and its electronics, including tool head wires, because leaving the printer on while conducting such tasks can cause a short circuit, which can lead to additional electronic damage and safety hazards.
When you perform maintenane or troubleshooting on the printer, you may be required to disassemble some parts, including the hotend. This process can expose wires and electrical components that could potentially short circuit if they come into contact with each other or with other metal or electronic components while the printer is still on. This can damage the electronics of the printer and cause further damage.
Therefore, it's essential to switch off the printer and disconnect it from the power source before doing any maintenance work. This will prevent any short circuits or damage to the printer's electronics. By doing so, you can avoid potential damage to the printer's electronic components and ensure that the maintenance work is performed safely and effectively.

¶ Remove the faulty old Heatbed Surface Magnet
Whether it is a Heatbed Surface Magnet with holes or without holes, the removal operation is the same. Here we take a Heatbed Surface Magnet with holes as an example.
¶ Step 1 - Heat the Heatbed
Generally, a pre-heated heatbed can effectively help you remove the surface magnet from the heatbed more easily.
Start up the printer, set the heatbed temperature to about 50 degrees Celsius, and then turn off the printer and remove the power cable.
In order to facilitate the operation when attaching the new surface magnet, it is recommended to adjust the screws to be completely parallel to the holes of the surface magnet.

¶ Step 2 - Remove the Heatbed Surface Magnet
Pry up the surface magnetic with a scraper from the corner. Please note that the double-sided tape on the surface magnet should be taken away from the aluminum substrate along with the surface magnet, so as to avoid residual glue remaining on the surface of the aluminum substrate.
 |
 |
During the process of tearing off the surface magnetic, if there is any damage, it is recommended to pause, use the scraper to help pry up the remaining part, and then continue to tear off the surface magnet.
 |
 |
Tearing off the surface magnet is a process that requires a slow operation, and the position of the surface magnet needs to be constantly changed throughout the process. At the same time, because there is a heated bed, you need to wear insulated gloves to prevent high-temperature burns and blisters on your hands caused by prolonged contact with the hot surfaces.

¶ Step 3 - Clean the Aluminum Substrate
After removing the surface magnet, we need to clean the surface of the aluminum substrate before attaching a new one, such as removing residual glue, fingerprints, and oil stains on the surface. Spray alcohol on the surface of the aluminum substrate, and then clean the surface completely with a clean cloth.
¶ Install a new Heatbed Surface Magnet
¶ Step 1 - Confirm installation location
Before starting to attach the surface magnet, it is recommended to place it with protective paper on the surface of the heatbed and confirm the installation direction and position. Especially for the version with holes, you need to align the holes with the leveling screws.
¶ Step 2 - Attach the Heatbed Surface Magnet
When attaching the surface magnetic with holes, first remove some part of the protective paper, then align the two holes with the two leveling screws on the front, and finally pull out the protective paper from front to back, and attach the surface magnet to the heatbed;
 |
 |
For the surface magnet without holes, it is recommended to align the right edge first, leaving a gap of about 0.5mm between the surface magnet and the heated's right edge, and keep the inner and outer sides parallel. Then pull out the protective paper to the left, so that the surface magnet is attached to the aluminum substrate of the heatbed from right to left.
 |
 |
 |
Please note that during the process of attaching the surface magnet, do not press the surface magnet with your hand, and pay attention to whether there is any offset, and you can make appropriate fine adjustments.
If a small deviation is found after attaching the surface magnetic, but it does not exceed the edge strip of the heatbed, there is no need to reattach it. The process of removing the surface magnet may cause wrinkles in the surface magnet.
¶ Step 3 - Clean and Pressurize
After confirming that the surface magnet is in place, you can clean it. Dip some alcohol on the clean cloth, clean the surface through a back-and-forth cleaning cycle, and apply moderate pressure to squeeze the surface magnet while cleaning to make it more firmly.

¶ Verify the functionality
After replacing the surface magnet, please refer to the Manual Bed Tramming to perform a manual leveling operation.
¶ Calibration
After the operation is completed, it is recommended to perform a printer calibration to ensure that the heatbed and some related components can work normally.
