So, after using the Thunder Laser for about 4 months off and on, I have noticed the details in some areas are squiggly or shaky. This became noticeable when I tried to do some etching with limited success. This is caused by the entire table (and arm) shaking after re-positioning the laser at full speed. Adding either a delay after the movement of the laser OR decreasing the maximum non-cutting movement speed should fix the issue.
Let me know how I can help!
