My LR4 build: thank you, and advice on a removable laser enclosure

LowRider CNC Your Builds

Hi everyone,

First, a big thank you for this fantastic project and its excellent documentation! I contribute to several open-source projects and write documentation myself, so I know how much work goes into making a project this approachable. You’ve done a wonderful job.

I’ve shared my LowRider 4 building experience on my blog, in French:

The machine is also part of my small workshop project, “Fabrique Artisanale de Bidule”: making custom objects, prototypes and replacement parts, with woodworking, 3D printing and CNC:

I’m now considering adding a LaserTree LT-80W-AA-PRO, 10 W optical power, 24 V kit, with air assist:

My main use would be engraving and occasionally cutting thin, laser-compatible plywood, around 2–4 mm. My LR4 uses a Jackpot3 with FluidNC, and I’m planning to adapt Doug Joseph’s kinematic quick-change accessory mount.

I’d appreciate some advice on the enclosure. My table is against two OSB walls in a small wooden workshop. I’m considering an opaque enclosure with an internal camera, and removable front and top panels so I can switch back to milling.

For those using a laser on a LowRider:

  • Have you fully enclosed the machine? If so, how did you build it: materials, removable panels, ventilation and door interlocks? Photos or build threads would be very helpful.

  • If you use an open setup, why did you choose that arrangement, and what precautions or operating conditions do you rely on?

  • What would you recommend for occasional engraving and thin-plywood cutting on a machine that is primarily a router?

I’ve seen several open setups in videos, but I’d like to understand the reasoning and recommended precautions before deciding how to build mine.

Thanks for your advice—and again, thank you for all the work on this project!

Welcome to the crew and thanks for sharing your project in other places for me!

As for laser safety… you can never be too safe. Most people here are very cautious and lasers are a serious business. The more people that could possibly come into the work area, the more safety you need to take for their sake.

A full cover is a great idea but I feel you really do need a way to see into the enclosure to check for fire or issues. They make laser safe plastic that should not be to costly, and I don’t think you would need a very big piece if you oriented it well.

You know pets too!!! I saw a YouTube where they recognized we need to be more conscious of ANYTHING that can simply be blinded, dogs cats, etc!

They can also do more than be blinded, just be aware and you should be good and enjoy!
