Hobby Laser 12 x 20 Model B
Illustrator CC 2015 1.0

This is not consistent yet I have spent hours and can not figure it out.

Some objects I print from illustrator only do one pass/cut of an object. Retina is set to one pass.
Yet others do two pass/cuts. Rentina Engrave is set to one pass.

EXAMPLE: Retina engrave shows 70 polylines yet there are really only 35.
If you highlight each poly line and change the color from black to red, you then end up with 35 red polylines, and 35 black polylines. It is like there are two lines on top of each other.

In illustrator I have tried everything in setting the stroke to like 0.000001 or 0.014, etc. (believe me I have tried many stroke sizes) Using Uniform and basic as the line types.

Some objects I print work just fine (correct # of polylines, and only one pass/cut with 0.014 as the stroke, and other times with different objects and same settings it is double the polylines and cuts twice.

There has got to be a simple answer I can not fine. HELP!

I'm going to make an assumption here... I bet these are drawings that you pulled from the internet. If so then this seems to be a reoccurring problem users are having. Many times drawings that are pulled have either multiple layers or multiple lines on top of each other. That is why you only see 35 but RE sees double the amount.

Your going to have to figure out how to either separate the layers or created a new vector outline of the drawing and discard the original. I am not an expert in illustrator so I can't personally help you on that part, but I'll bet that is the basics of your problem..

In this case/problem I was working on today, the simple objects were created in Illustrator. Nothing imported.

I do have other files that contain both objects created in illustrator and objects brought in from the internet. The objects brought in to illustrator were png, and then I used the trace feature to turn them into a vector.

Thanks for the reply.

Make sure your line thickness is super low. If it's too thick RE will trace both the inside and outside of the line.

Check and see if Align Stroke is set to Outside.
I remember testing this last year for someone else and Align Stroke to Center was causing double lines regardless of thickness.

I use AL as well.. and used to get 'double' cuts on my outlines as well..

(and even rastering of my lines at times)

1.) check ignore small vector (I think thats the setting, I'm a work currently..sorry)

2.) make sure your outlines/strokes are set to 0.001px I know some odd thickness settings have given me the 'double cut' as well..

I can post a known working AI file to try running when I got home if you like.

SUCCESS: Adobe Illustrator version 2015 or 2017

Settings to avoid double cuts on lines.


Stroke .5PT or .001IN
There can be no fill on the line (my problem)

Additional settings I had

Variable width profile - Uniform
Brush Definition Basic

Working like a charm now. Getting single cuts.
