# New rotary set up?

I got a chuck rotary, i set it up and when i start the burn it spins the cup 70 degrees. How do i set up a start point or just make it burn where i set the head to?

I have watched videos but most are of the set up and do not go into detail.

IDK, what i am missing. On a MAC running LB 1.6.0

Thanks

Do you have a machine console or is this a Polar?

My badâ€¦ an Omtech 80w. R&B

So is it working ok with the test button in the gui?

Are you using the Y axes for the rotary?

The test works, yes y axis. IDK if i am setting it up wrong. I am a moron and struggle with this stuff. I can get it to burn, i have the spacing. But setting the home and where to start is where i am struggling. WHy does it spin it when starting?

I am combing YT and trying to find a in depth video on my problem. (Other then my stupid brain) LOL

Again sorry, IDK if i am missing any info. Thanks for the help!

Just throwing spaghetti at the wall, if your artwork is say 140mm wide and more or less centered, your rotary should spin back 70mm, then proceed to burn the 140mm art.

OK yes, it needs to go to the edge. I get that but it spins 40% and startsâ€¦ I think i has to do with the home or start point.

IDK, thanks for the info.

Also, I am actually having spaghetti for lunch! so statement is perfect!! LOL

Youâ€™re just not clear on how all of this works (or doesnâ€™t) together. First is the coordinate system.

There is a 0, 0 position in the coordinate system.

Where your machine homes, determines which quadrant itâ€™s operating within. Mine homes in the rear/left so Iâ€™m operating in Quadrant IV

You working area is defined within this quadrant.

This is always how these find their way aroundâ€¦ even with a rotary, the machine still thinks itâ€™s working on the flat, defined work area.

Start from, identifies to the system if you want it to generate coordinates that start at the absolute coordinate system point of 0, 0 or a user defined point (user origin - when you press origin on the console). There is also current location, which is where the head is located at that timeâ€¦ I havenâ€™t found a good use for this yet, but Iâ€™m sure there isâ€¦

If you choose absolute coordinates, then start from and job origin are not needed and canâ€™t be modified.

Job origin defines how the code is generated relative to this user defined point.

Rotariesâ€¦ they are just a table wrapped around something and the controller still thinks of it as a flat work area.

How you power up your machine impacts how you configure it.

If youâ€™ve swapped out the Y for the rotary and powered up the machine, you must press to stop it from homing as there is no home switch on these rotaries.

Check out the X and Y values on the console. These values canâ€™t go negative or above 10000

I spin my Y axes far enough so the artwork is within the machines defined work area. If you esc out of the boot, both number should be 10000.

Move the gantry over the rotary and use the buttons to align the X axes over the start position and press origin on the console.

Ensure artwork is set for a start from of user origin and a the center left of the job origin.

This allows me to set the mug up with itâ€™s logo under the nozzle. It will then engrave with the artwork centered over the mugs logo. This wraps most of the mug, but you can see the logo (large stamped triangle) at the bottom left of the mug. I used this to center the mugâ€¦

Make sense?

WOW OK thanks!!! Yes,I will go try it out!!! Let ya knowâ€¦

Weird question, does resetting the machine do it, or power off and on? When adding the rotary.

Do what?

GOT IT!!! Thanks for all the help!

Itâ€™s nice for others looking for an answer to find it. If you donâ€™t comment or indicate which thread you based the solution on, itâ€™s less helpful to otherâ€¦

Glad youâ€™re up and running againâ€¦

Have fun
