Ok not sure how to explain this issue being I can not seem to upload and image. This issue has happened a few times different files but same laser. So I assume it is a laser issue. 45 watt Epilog Mini Helix. What happens is I have a design like a square with a smaller square inside the engraving goes first then the cut. The engraving can be off to the side some or completely curved sides. I will see if I can post a pick on a follow up post.

below the reply box to the right are 'post quick reply', 'go advanced' and 'cancel' buttons, click 'go advanced'--

new screen comes up, scroll down till you see the 'manage attachments' button, click that...

another 1/4 sized window should pop up, towards the top right corner click on 'add files'- then hit 'browse'--

find the pic on your computer, click 'open', then click the 'upload' button...

--do this for as many pics as you want... they will stack up along the bottom... when ready hit the 'insert inline' button, and the thumbnails will be inserted into your reply box...
you can move them around just like text, or drag with the mouse to move them...

this of course assumes you've never done this, if you know this and you can't upload, I haven't a clue! :D

THAT all said-- does your Epi have steppers or servo YX motors? If servos, sounds like a classic case of dirty encoder strips...

hope someone has an idea I have cleaned the encoder strip already also.

I encountered something kind of similar when the pair of finger screws on the laser head that keep it attached to the moving part were loose, maybe check that?

The encoder strip may be nice and clean--the strip is "read" by a contrast reader (little black thing the strip sits in).
I have had similar issues to what you are experiencing and Epilog support had me look at this.
Was loaded with all kinds of fibers. Mostly q-tip fibers from cleaning stuff and oiling rails.....
Maybe it'll wok for you??

^^ this thread concerning encoder issues was posted up a few weeks ago- in post #13 John Noell provided a link to a video showing how to clean the encoder and reader on an Epilog, very good at showing how to do it-- however, as I mentioned in that thread, the guy cleaned the strip by simply wiping it lengthwise with a Qtip, which I don't agree with. The reason is because of the micro-lines in the strip that are 'read' are molded into the strip, perpendicular to the length; they're like file teeth, and as with files, if you want to clean between the teeth just wiping 'against the grain' isn't going to be very productive. It's tedious but IMO you should clean between the strip lines for the length of the strip rather than a quick swipe down the length...

THanks for all the response swapping out encoder strip.
