For people who have model drop problems. Please note that each method is connected to each other. 1. First, polish your platform according to the original factory's tutorial. I probably only make the pattern of each position look the same. I use an arc-shaped technique. 2. The leveling method suitable for SM4K is to fix the platform, loosen the four screws, then pull the platform down by hand, and click on the Z axis to level. This action is to make the LCD directly push the platform to form a theoretical parallel , And finally use a hand to help flatten and then lock. After leveling, please note that you need to distinguish between the front and the back of the platform. It is best to make a mark or there is a groove on the platform. Please pay attention to the direction you choose at the beginning of leveling, and be careful not to put it upside down every time afterwards. If you still have a falling problem so far, you need to be patient and repeat the operation. If it still doesn't work, please continue to see the next suggestions. 3. Replace the light-shielding tape around the LCD to 0.05mm~0.15mm (please repeat the second action to change the thickness). Reason: I have mentioned in other people’s questions before, the thickness of the tape made by PHROZEN is about 0.3mm, The thickness of FEP is 0.15mm. For the time being, regardless of the fact that the center collapses after the fep is placed on the material, the material at this time is 0.45mm away from the LCD panel. When the platform is pressed down, it will cause the FEP to not adhere to the LCD panel and the platform. After the third action is completed, if it still does not stick, please note that I do not recommend the following method. Please bear the consequences before using it, although I have been using this method on some devices. 4. Perform z-axis leveling directly without placing paper. That's right, the platform is directly attached to the LCD panel. Please pay attention to wipe before use to ensure that no black grease can be wiped out on the platform and make sure it is clean. In order to avoid discrepancies, it is recommended to use the original lake water gray resin and the ambient temperature is around 25°C, and the bottom layer exposure time is 25s-35s. Tips: Choose none for the model Raft shpae, and 0.2mm thickness for the bottom is enough.
