Was thinking the same exact thing

I created some tall 3D printed hold downs with magnets in the bottom to grab the material and hold it in place.

The camera is pointing down and to the center with the lid opened. There's simply not enough clearance to mount to have a view of the entire bed with the lid closed. This is also not possible because the camera would need to have an extremely wide field of view which isn't feasible.

I've got the Omtech 55. Spec-wise, the tube is a 50w though.

Thanks, I've found that you can never have enough reinforcement in the mold box to prevent leaks.

so far, so good.

Please be safe. Maybe anchor your object or don't put your hand down range, at the very least.

I don't know if it will work with RDWorks. I've only used the camera with Lightburn. The camera I purchased was from Lightburn as well. I've used a webcam with lightburn in the past, however, the resolution wasn't as good.

@@DabooDesigns thanks for answering. I was thinking also to just do it with lightburn and simply all my hustle

Thanks for letting me know. I have fixed the link.

The camera connects via USB to the computer.

Thanks!

Glad to help

I look forward to seeing your setup.

I tried a roller and didn't have much luck. It was imprecise and squeezed over the edges.

I started using foam roller and works really well. No spill outs when wood pressed together. If there is, then it means you had to much glue on the roller.

I used the guide here to determine the correct lens for my mounting height: lightburnsoftware.com/collections/cameras/products/lightburn-camera-4k-w

Here's the one I installed in my laser: www.amazon.com/gp/product/B01DXYMJ94/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Our pleasure!

Since each layer is painted before gluing them together, I find spray adhesive to be too messy.

I've sold a few. I did these mostly because I was interested in how thin I could cut material and play with some cool finishing techniques.

​@@DabooDesigns what type of equipment do you use or Laser machine looking to buy one

My laser is a heavily upgraded Omtech 55w. The stock machine will do the trick though.

I do not currently have a filter installed. My exhaust fan is 390CFM.

Nope, it doesn't matter.

I believe it's 16 gauge. I had a friend cut it and put a bend in it to keep it level.

I found this pattern on Etsy. There are quite a few to choose from.

Thanks for your order. The gripper hand mechanics are crazy complicated. I had to take another one of my bots apart to figure out how to get the first one back together correctly.

@@DabooDesigns Thanks! Got the parts! And now of course I can't work out how to put the claw back together ;-) Update: my 14 year-old helped me. We found an exploded schematic and that really helped.

@@GrantMeStrength Yay! I'm so glad you were able to get it back together.

@@GrantMeStrength I found a "service Manual" but it doesn't show the reassembly of arm or claw - did you find a schematic diagram for just the claw?

I'm so glad they're working well. I hope you found all the parts. :)

There are plenty of ways to mod the Omnibot Junior. There's a Omnibot group on Facebook I highly recommend. Post your questions there and some of the great minds of the group will likely be able to assist. facebook.com/groups/omnibot. There's also a Discord Channel called Omnibot Enthusiasts, I recommend joining.

@@DabooDesigns Thanks so much for the link to that group... My wallet wont thank you, but my heart does. :D

The horse is not my design. I think I bought the pattern on ETSY.

I designed and 3D Printed them.

I'm not sure I follow what you're asking. There's a link to the plans.

The camera needs to be far enough away from the bed to see the entire area. Drilling a hole in the middle to view the bed is too close and won't get the entire bed. This configuration works quite well. I open the lid, insert the material to be cut or engraved. Adjust the design in lightburn or shift the material and take another snapshot. Close the lid, and fire up the laser. As for smoke on the lens. It's not an issue worth solving. If it gets a bit foggy, which it hasn't. even after months of regular use. I'll wipe it with the same qtip and iso I use to clean my lens and mirrors.

@@DabooDesigns Awesome! I was just curious and thought it would be worth asking

I spray on a clear coat over the entire piece after it’s assembled.

Glad it helped

In my experience, ca glue gets brittle over time. This is especially true for some of the thinner sections I do on other pieces. A slight pinch on the outer layer will cause the layers to separate. The Elmer’s glue is more flexible and durable. This is the best way I’ve discovered so far, however, I’m always looking for simpler and better ways to get the job done.

@@DienhartDotCom I haven't had that issue. I have clocks & layered art that's over 5 years old, a couple on my covered patio with no problems at all David. I do know one person that mixes CA and wood glue, 50/50 and he swears by it.

@@TheLouisianaHobbyGuy cool, thanks, Rich. I may do some more experimenting.

@@DienhartDotCom I picked up his idea and started mixing Tight Bond 3 50/50. Too soon to see the results though. Only been doing it about 3 months now.

My experience is also ca crystalizes over time and fails long term.

Thanks a lot

Great question, I just now added the list of parts to the description.

My pleasure

The files are here: daboodesigns.com/blogs/info/improved-exhaust-airflow-for-the-omtech-55w-co2-laser-engraver

You do not need to align the camera since the surface of whatever is being cut or engraved is still at the same distance from the head.

This file isn't terribly usable. I was just using it for getting the feel for my 3D Scanner. I may circle back around and give it another scan and make it available.

I'm not sure. Feel free to download the file from here and see: daboodesigns.com/blogs/info/improved-exhaust-airflow-for-the-omtech-55w-co2-laser-engraver

Glad I could help!

While that is likely true, I get excellent airflow end to end. The more controlled flow make a huge difference.

85 degree

@@DabooDesigns Why 85 degrees? What's your bed size? I'm looking at a 120W for a 500mmx700mm (20" x 28"). Seems that would give me the most optionality given that Lightburn software corrects for distortion. I'd mount it approximately the same area assuming the lid is open. What am I missing?
