Thank you very much for your understanding and support. Regarding the issue of the main body arching, as you mentioned, it is usually caused by the silicone strip being cut too long. When the silicone strip is too long, the nozzle exerts a downward force on the silicone strip during repeated wiping, causing the main body to arch.
To solve this problem, it is crucial to ensure that the silicone strip is of the appropriate length. When the silicone strip is of the right length, the arching of the main body will be greatly improved under normal working conditions, and this issue may even disappear completely.
Therefore, I suggest that you try cutting the silicone strip slightly shorter, which can reduce the downward force exerted by the nozzle on the silicone strip during wiping. At the same time, to achieve more accurate cutting of the silicone strip, you can try using the cutting model I recommended. This cutting model has been carefully designed to help you more accurately control the cutting length and ensure that the silicone strip meets the required length.
