Wobbly and not aligned engravings

Post by Philscraftcorner »

Hi there. I'm new to. Laser engraving and purchased a cheap 500mw unbranded laser from ebay. I know the laser is pretty poor and I have managed to focus it well and get it burning really good be it really slowly.

My issue is that after a couple of minutes of running almost perfectly it starts to. Skip lines or the lines go wobbly and don't line up. I have tried the default benbox software, eleksmaker Pro software, T2 laser and lightburn. Lightburn has given the best results for me so far

From what I can tell the issue comes with the fact that I only have one stepper motor supplied for the y-axis. And a rod that locks into both sides to make the other side of the y-axis move. (See picture)

This has likely been asked before but I couldn't see anything. I have spent atleast 5 days messing with this thing and these are the best results I can get (see attached).
I appreciate any help or info provided

This started frok the top down. The laser seemed to focus more and the lines went wobbly
