Sculpfun provided me an S9 laser to review. Shortly before they officially released their 33 watt upgrade kit they also sent me one to review. After installation I noted that when doing small “LINE” engravings that the laser had to slowed down considerably. I ordered and installed the Sculpfun Linear Rail Kit to see if it improved stability.

Boy, did it ever.

The pic pretty well illustrates the issue. Heavy motor on the top pulling one direction, and heavy and large laser module pulling in the other direction.

Again, I need to state that this configuration works……you just have to slow things down a bit.
