I have a boss laser engraver. I only do plastic ID labels for commercial construction and am quite busy this time of year. I've been getting by with using only the left side to engrave on for the past month. I've had my engraver for 1.5 years but have never used it much until March rolled around. I have never had this problem and it started only 1 month ago. Is there anyone in my area that could possibly help me out? I've tried doing the 4 point test. That isn't working out for me. I'm sure the issue is more than likely between the steering wheel and the front seat.
