Currently 2 months into laser Experience and i Absolutely love it!
I recently upgraded to a 20w laser module from a 7w module! I noticed the lens may be different. with the 7w i was able to focus it quite well almost perfectly. it came out almost like a perfect circle. With This new laser module it seems the laser is alot more linear. it does not make a circular shape and when burning you can easily tell it not focused correctly.
Can it be using a different lens? i feel the lens could be different! any thoughts suggestions here?
