A stock OMTech Polar includes 2 different rotary's that are limited to engraving objects with a diameter between 30-74mm. By creating these leg risers, you will now have the added space that you need to engrave many styles of 20 oz tumblers or larger diameter objects.

Very cool. We are getting ready to order our Polar. Thanks for this video.
The rotary limitation on the spec sheet was one of my main concerns on deciding on this machine. It’s really nice to see how you adress this problem, and better yet, that you took your time to bring it up with Omtech directly.
Some people wanted an extension cord. You can make your own or a found this guy on Etsy that sells stepper extension cables. I bought the 5 inch and it works great

I'm waiting on mine to arrive. Watching your videos have been extremely helpful.
I’ve got ,mine ordered and will definitely have to save a light burn file to do this as soon as it arrives
Actually creating the files takes like 5 minutes. It'll take you no time!
At 8:30 you point out about the cord length for the rotary. If you open the rotary and rotate the stepper so the connector faces up, that should help a slight bit. Granted you won't get much extra length, but you'll get some.
You know I never even looked at that. With these risers the line is pretty tight so it may be just enough slack to give someone what they need. Good eye! I did speak with OMTech COO and they're making it with longer wires for this reason. I'm sure my video will be obsolete once they figure out they can market leg risers.
Hey Dan - This is Cam Edmonds BTW - the admin for the OMTech group lol
This is fucking awesome bro saving people lots of money on a upgrade
You are AWESOME! Thank you.
You are so welcome!
Very useful information for polar laser users 👍
Awesome! Hope it helps!
Very helpful! Thanks man. Appreciate these videos. Still waiting for mine to be shipped, but looking forward to it.
Trying to share some tricks as they come up. Thanks for watching!
Good to know about this. I'm waiting for you to make a video about the camera. I want to know how good it is before I make up my mind and pull the trigger. I think that would be my favorite feature of this laser. Thanks for the video!! Much appreciated!
thank you!
You’re welcome!
Thanks for the tutorial! I will definitely be making these. How do you determine focal distance with the risers? I haven't tried tumblers yet.
Your focal distance is “the distance between your workpiece and your nozzle.” That distance doesn’t ever change. Our polars work backwards to where we have to put input an offset to move the laser head down, but what we really need to know is the distance between the workpiece and the material. What I did is that I found a piece of material that fit perfectly between my workpiece and laser nozzle (after I set the nozzle) and that material will act as a gauge to measure how far off my laser nozzle will need to be from my tumbler. It will take bit of trial and error because our polar is driven by incremental inputs in lightburn
@@EdmondsWoodshop Thanks, Cam! Sounds like it will take some practice!
Would you be able to make a riser for the rotary also? I’m not tech savvy at all so I hope that didn’t sound dumb lol.
I’ve trying to engrave silicone watch bands what settings range would you start I’ve tried everything
Ive been looking at this machine and the xtool p2 but still undecided since ima a first time user/buyer i wanna make signs/logos for people and i wanna make those acrylic led stands with characters as well as lots of other little ideas i just want something under 5k decent quality and for the learning curve to not be too steep as far as using the machine which do you recommend
What computer system do you use? I just bought my own polar and I know a need a new computer bc my chromebook won't work for it
so the polar cant do the 40oz tumbler wraps?
Hey. I just wanted to stop by and ask if you were able to test out any other tumbler sizes/diameters.
Also, any word on if there will be an extension chord for sure? Thanks. Ordered my Polar. Upgrading from a D1. Super excited.
You can easily find an extension cable by searching for “stepper motor extension cable” on Amazon. The only problem is that you won’t know how they’re wired until you get get them. Some come reversed so you’ll have to swap the two outside wires around.
This is perfect. Quick question, how do you calculate the focus height post riser install?
I think the polar has an auto focus. You're not doing anything to really change the height from the POV of the laser.
Your tool box actually has a ruler with a notch cutout labeled 50.8. This cutout sides on the frame of where the lens sits. you would adjust your height of the laser head until the bottom of that ruler is touching the cup
Great video! Forgive me for what may be a dumb question. I'm new to all of this and considering getting a Polar. How would you focus the laser on the tumbler after doing this?
There’s a ruler in the tool box that has a 50.8mm notch on it. You set that on the z axis and lower until the bottom of the ruler touches the cup
After you add the risers do you know what the max diameter of the tumbler (and length of an insulated water bottle) can be? I know they all can have different lengths/ diameter based on shape of bottle. Thanks! Your videos are very helpful! Can’t wait for my polar to show up!
I don’t know the max diameter. I just had 20 oz tumblers on hand to check. Heck, you might be able to do 30 oz. As far as the length, the rotary is adjustable. I’ll have to measure how far down it can adjust to.
Thank you for all your help!
Great Video! How do you keep the tumbler from moving left/right as it spins? My diode laser has a chuck style rotary.
How do you handle the focusing when using your risers?
The polar comes with two rotary’s. One for wider object and one for narrow objects. I also keep two different settings for when I use my rotary versus when I use my default laser settings for normal operation. For my rotary settings I keep my speed way down. I don’t have moving issues.
I only use the risers for objects that are wider than what the stock setup allows. I use the included ruler to focus my laser head to the top of my tumbers surface.
@@EdmondsWoodshop thanks!
Can’t you just solder some similar gauge wire and make an extension? Then add some heat shrink to cover the wires back up? That way you could laser a larger tumbler? But, maybe make the feet a bit larger due to the increased height.
Absolutely! Being the admin for the Polar group, I would say more people are afraid to do that than buy an extension cable. If you're comfortable with then, then by all means.....you absolutely can. And yes, you would need to make the risers taller if you needed more depth.
They also make extension cables for 3D printers that will work for this as well and can be found on amazon. You just have to make sure the male and female ends can plug into each other. The one's I found on amazon were sold out, but I found someone on etsy to make me one.
@@EdmondsWoodshop I’ve got 20 years of car audio and other electronics experience with soldering. A little soldering doesn’t scare me. LOL
I'm following your page as we're contemplating a Polar. I'm far from "techy" but do you think this is a good starter machine? It gets so confusing researching all of them and I'm still confused what the difference of other 2, cheaper, desk top models are, other than speed, camera or no camera, and work area! Thank you for this video too. It will be helpful down the road should we make that leap! It's looking likely though!
Hi Karla. The nice thing about the polar is that it's ready out of the crate. There will still be a learning curve with the software and the functions of the machine, but as far as general setup goes, you'll be good to go. The polar is bit different from OMTech's other models just because of it's general makeup. It includes all the necessary accessories to get started where on the bigger models you might need to buy the extras such as the inline fans, the chillers, the LED's, etc.
However, with the bigger machines you obviously get bigger space, more versatility as far as engraving larger objects. The trade off is that you need to learn how to properly set up a laser. This means learning how to align mirrors and do a ramp test. Its not bad, but can be a tedious process. We have tutorial videos for all of it.
If you haven't already, I am an admin for the Offical OMTech group. I'm partnered with BeardedBuildsco (another laser channel here on youtube) and we help thousands of people like yourself narrow down your research.

@@EdmondsWoodshop Thank you so much for your quick reply! That's one of the reasons we're leaning towards the Polar, everything comes with it and basically just ready to go! A little more space for working than the other 2 desktop models, but not overly huge. Perfect for projects I would like to do! Right now anyway, who knows down the road, but set up, aligning mirrors and all that doesn't sound like that's for me right now!! LOL!
I really appreciate your videos, time, comments and insight! I'll make sure I hop on the other pages as well!! Research is fun, to a point! LOL! I just want to create now!!
I am familiar with the Cricut craft line for crafting, cutting paper, vinyl, etc., and using Design Space (which is a pain sometimes) but it actually seems pretty similar to Light Burn, although light burn seems even easier!!
Thanks again, I appreciate it!
Does the polar come with the rotary?
Yes it comes with a rotary
Wow I just saw your video. That it's not good news for me. I just bought the machine I am waiting to be deliver. I watch to do 40oz 😢
Actually people in my polar FB group have figured out how to do the 40oz Stanley’s. Join our Polar community! Link is in the description
are u omtech distributor?
Nope. Just a regular user. I do manage their official Facebook users group
@@EdmondsWoodshop thats cool, do u have any blog?
