Going out of mind and have wasted soo much material. My laser isn't cutting in the middle of my sheets. I have an Epilog.

The outer edges cut fine however middle parts loose power almost completely

Photo attached, any help or advice would be greatly appreciated

The three things to generally look at with situations like this are: bed alignment, laser alignment and the state of your optics.

I suspect that it's most likely to be crap on the optics, since that's the most common cause for issues like this (unless you've dropped something heavy on the bed recently). Examine the lens and the mirrors carefully - even a little discolouration on them can cause issues akin to this. Clean them with alcohol lens wipes or the nearest equivalent you can lay hands on.

I’ve cleaned the lens and mirrors .. was also told the issue could lie in the material but it’s not warped at all

How's your beam alignment looking? I'm not seeing any of the normal 'halo' I'd expect from a misaligned beam, but it's easier to check and resolve than a misaligned bed is.

HI
we have this problem with 3 mm mdf, we have found it is in the winter months when there is more moisture content in the materials stored in cold warehouses and workshops
we counter it by increasing power slightly during the winter and that cures the problem
give it a try let us know

We’re In Australia so it’s currently summer here.. materials are not cold at all ??QUOTE=Dtcrafts;2236716]HI
