laser

Operative question: what are you planning to do with it.

For those of us who don't have access to a spirit level, there's a Tim Allen power tool out this Christmas. Combined stud finder and laser level.

You locate the stuck, flip the sucker to hold it in position on the wall, and fire off the laser. You then use the laser (perfectly horizontal mark across the wall) to locate whatever needs to be made level (like shelves for all the wonderful things your kids made in school.)

However, very VERY VERY >>>>VERY<<<< careful with lasers. Even the low-powered lasers such as the lecture pointers have enough oomph to do serious retianl damage.

Follow all safety notes TO THE LETTER.

I don't think anyone wants to be called "dead-eye Dick"

Sounds like you just need a large flatbed pen-plotter now.

I have three HP750C plotters, an HP1050C and a KIP Multiple media laser plotter at work. Why would I want a pen plotter?

I figured you could strap the co2 laser to it. I wasn't aware you already had a laser plotter - and I know you can get pen plotters cheap at college surplus sales. I tend to make things instead of buy them.

The cutting laser has an 18" x 24" cutting table capacity and a lathe turning accessory so you can laser engrave round objects such as wine bottles and coffee mugs.

I have got the autocad, plotter, shop, time, but no laser.
Maybe after the lottery tomorrow I will buy everybody a laser.

What a lucky guy. Do you live in BEDFORD FALL (wonderful life)

Let us know how it works out for you.

It's not MY laser, I just have unlimited access to it. If you want to send me a *.dwg or *.dxf file, I can get your stuff cut for a nominal fee.

Who is the manufacturer of the laser and what are the dimensions of the cutting table? What program is it using (specific not CAD/CAM)?

DR. Jet stated earlier in this thread the table was 18x24" which likely makes it a system from Universal. They supply their systems with Corel Draw which can read DXF files. While I have never used one of their systems they seem to drive the laser like it was a printer or plotter. Universal makes a decent machine even if they seem over priced. The table is too small for my needs/tastes. I just got a sale flier from them today claiming to have 30 watt systems starting at $13K on a year end special.

Oh yeah I see where he mentioned the size earlier. That's not a bad size - enough for basically four standard (4" by 24") balsa or ply sheets. Yeah Universal makes great systems but the pricing is way up there. I looked at Epilog and a few others as well but they all run about the same price. After talking with a guy that sells a nice foam cutter setup he set me up with four stepper motors, power supply, and motor controller for about $150. Along with parts from Home Depot I'm almost finished with the CNC table. Mine will be 21" by 24" but the next time I build one it will be 24" by 24". So far the whole setup has cost less that $200. The laser is the most expensive but with a handy construction manual from Emission Technologies I should be able to put together a 55 watt laser for a relatively low price. I plan to use MasterCAM software and make the y,z axis removable and replacable for CNC milling and foam cutting. Basically a "universal" table for less than $1000. Not only will it do laser cutting and engraving but also foam cutting, 3D modeling, and virtually any other application you can think of. I think most of the optics and power equipment can be found on E-Bay as well for decent prices. I don't get back to LA until the 5th of January but once back I will put together a few pics and post them.
