Ran into my first issue last night. It seems that the machining tolerances were not quite tight enough for my machine. One of the bearings for the y axis drive shaft that operates the left side of the gantry walked out of its carrier. I spent several hours last night and again this morning trying to sort out the issue.

The machine would not cut a perfect circle on the left side of the bed. The right side was close, but still had some wobble. I tightened everything, cleaned and relubricated, still no luck. I finally noticed the left side of the gantry had some movement to it when I would try and manipulate it by hand. I tried like hell to find something to adjust the tension, or tighten the gears only to summize that they were all press fit, and not very tight fitting.

Finally, I noticed that the bearing that the left side of the drive axle was not supported by anything. So I loosened the set screw on the coupler at the stepper motor, reset the bearing, and tightened everything back down.

Everything seems fine now, however, my question now is, what in the hell allowed it to walk out like that.

I can add acrylic to the list of successful cuts. One was cut mirrored for a smooth front, the other cut on the front face. The area that appears to be burned is smoke staining from the plywood I used as a spacer to create an aitspace and prevent flame ups.

The edge lit stuff.

I've found a few pre made stands, but they are not cost effective

Those are cool. If you do the little less acrylic pieces, do the places sell the little stands too or do you have to source those elsewhere? I've bought a few of those as gifts before.

I'm stuck with scrap material working up new designs. We won't have anymore 1/8" sheets until tomorrow, hopefully

I think you're just seeing the bare aluminum after you've burned through the anodizing....but it's hard to tell from the pic.



How'd yall end up doing at the fair?

Could be.

We did ok. $400 in sales, lots of interest, and gave out a lot of cards.

We focused too much on "big" items. Cutting boards, door hangers, etc. We are planning a lot of smaller items for the next one to capture the "lookers" or the "oh thats cool but I'm not paying $20 for a bigger item" type people

Aparently, black anodizing turns white/light gray....FYI

A Christmas Market at a local church here in Greenville. Wesley United Methodist. We will be there from 10 to 2 tomorrow

My wife was planning to go to a Christmas Fair here in Plano today so I thought it might be the same place. She is quite crafty also and I've kept her up with your progress with the laser engraver. I was going to have her look for your crew.

Edgelit Acrylic can be tooled easily with a CNC router and can produce striking effects. It's available in multiple colors from different manufacturers. Flame polishing with a torch can make the edge really shine. This can also remove light scratches from the surface.

Lots of commercial plastic shops around town that build displays use it and the industrial plastic supply houses should have it in stock. Try Regal Plastics or Laird Plastics if you are looking for this in large sheets.

Correct, cast acrylic is what you want for sure. The finished product can really pop if done correctly.

Aaaand. Now, I'm on google
