I purchased "xtool M1" last May 2023.
It's been a little over a year since I bought it, but I'm having trouble because the performance has deteriorated much more than when I bought it.

For example, cutting 1mm thick MDF material.
[Before]
Power: 100% Speed: 10mm/s Number of times: 1
[Current] 
Power: 100% Speed: 10mm/s Number of times: 3-4

What is even more troubling is that the cut cannot be made depending on the location of the machining area.
It seems like it's out of focus in some places.
For this reason, large-sized pictures cannot be processed.

Thank you for your understanding as I am in serious trouble.
