That's great Ernest! I won't be able to spend time working on it for a few weeks, great to know the tube can be recharged/repaired :)

Thanks for the replies! I have a few (non-laser) things to do before talking to Epilog...

Mike, I'm a fanatic about focus, usually at least double check, even between runs.

Chris, I have the...

After engraving for a few hours today, the power of my Summit suddenly plummeted. :(

One run was great, then the next was terrible. It barely marks in raster mode now after a few simple tests,...

Brilliant! Very useful, thank you for sharing it here.

Curious if any of you got homebrew air assists working-- any drawings, photos, or videos to share?

With my air scrubber mostly complete, I'm starting on air assist for my Summit, but all I have is...

OK, so I'm not crazy! The picture is an 8-bit BMP, a format I'm not used to dealing with, but figured using a Windows format with no (real) compression would be a good bet.

It's a pig-- the first...

OK, strange one here...

I imported a bitmap image (8-bit), set up some text, and moved everything to position. Looked great. This was to engrave on a glass; my first glass and first use of the...

Thanks Greg! I'll try masking tape next time I cut. I'm also taking measurements of the innards and sketching out homemade air assist ideas based on what I've seen.

I'm getting a little flame that scorches the 3mm masonite I've been using.

Did the Summit have any air assist option? Looking around, I can't find any reference to air assist on the Summit. ...

Interesting question... I want to generate some shapes programmatically with Python, so this is an interesting starting data set.

svg is open and well documented, so it's fairly easy to form in a...

Some of the first things I tested my laser on were tortillas and a banana, and I'll definitely offer a few plates of laser cut and etched food the next time I have a dinner party!

At a "laser...

Great thread, so helpful!

I got the green Harbor Freight unit and was surprised at how quiet it is.

However, it does vibrate a fair amount, and it's bugging the neighbors downstairs :o

I put...

Funny that one of the kitchen items shown is pills-- definitely part of the food service industry :)

I think I'll just go for it, not many other affordable options out there!

Finding carbon is trickier than I thought though, sure enough the grow stores charge outrageous prices... might just order...

Huh, HF lists the sound level for the red one ("107-112 at 3ft"?!) but not for the green one. I'll see if they'll let me plug them in before buying; too bad the 1.5hp Penn State ones won't be in...

Thanks for the replies! Yeah it looks like the commercial units are pricey. Richard, I do want to both clean the fumes and vent the filtered output. If I just vented everything to outside with a...

I've been lurking for a few months, figuring I wouldn't get a laser for quite a while. I'm a hobbyist (electronics mostly) and could imagine using a laser for making small cases, front panels,...
