content: I have unintentionally amassed a collection of laser cutters. Since I only ever use one at a time, I have decided to sell 2 of them.Since these are all fairly large, heavy, and somewhat fragile pieces of equipment, I would prefer local pickup (Louisville, KY). But if you want to pay for crating and freight, I am not opposed to shipping. I only want to sell 2 of the lasers (keeping either the Epilog or Trotec), but it doesn't really matter to me which I keep. I exhaust my laser outside, so I have no use for the filtration unit that I acquired with the Trotec.Laser #1G. Weike (Chinese) LG50060 Watt, water-cooled, glass laser tube20 inch by 12 inch cutting bedIncluded are an extra 60 watt laser tube, water pump, air assist pump, software, and parts kit included with the laserI had the stand, but one of the "welds" broke...luckily it broke just after a friend and I put it on a table.I also had the exhaust fan, but the motor broke after a few months of use. It was undersized for the application, so I have a much bigger exhaust fan hooked up to 2 lasers now.I purchased this laser new from a dealer in Chicago for $4000 in 2014. It has very low hours on the tube that is installed in the unit, and I talked the dealer into giving me a spare since they don't tend to last as long as solid-state laser emitters. The software is clunky, but useable. I have cut up to 1/4" thick acrylic and engraved lots of different materials.This link (http://www.wklaser.com/index.php?m=content&c=index&f=show&catid=128&l=2&id=251) has all of the correct specs, but the cabinet on my laser is blue instead of the gray shown.I'm trying to get around $750 for this one. Ebay prices for 60 watt Chinese lasers are in the $1700 range, and mine is nearly new anyway.Laser #2Epilog Mini24, manufactured in 200840 watt solid state, air-cooled laser (more powerful than the 60 watt, water-cooled tube)24 inch by 12 inch cutting bedSoftware is just a printer driver that you can use with your favorite graphics program (Corel, Adobe, AutoCAD, etc.)I will include an airbrush compressor and fittings that I have connected to the air assist inlet.This one is a bit more complex. It had a fire in the cutting bed in 2014. The electronics and motors were still in good shape, but the x-axis over the cutting bed was roasted. I replaced most of the x-axis parts, installed an entirely new cutting bed, and cleaned it up the best I could. I have been using this laser cutter exclusively for a side business (engraving name plates for businesses) for almost 2 years now. It is quirky. This thing was covered in fire extinguisher residue, so there are some rust issues that forced me to replace some bearings. It has a brand new main controller board, power supply, and focusing lens, too. I cannot tell exactly how many hours the laser tube has on it since I was not the original owner, but I haven't noticed any degradation in power that isn't solved by cleaning the lens and mirrors.I'm trying to get $5000 out of this one. I probably have about $2500 in parts invested in the restoration and continued maintenance. New Epilogs sell for $25k+. Working units older than mine go for $6500+ on eBay.Laser #3Trotec Speedy 300, manufactured in 201360 watt solid state laser (my most powerful laser)30 inch by 18 inch cutting bedIt comes with the original Trotec rolling standI will include a laptop loaded with the Trotec Job Control software (pretty pricey)This thing has an integral air compressor for air-assist.This is another fire salvage unit, but it was less damaged. The fire was in 2015, so the laser tube probably has pretty low hours on it. I was able to score a brand new complete x-axis which resolved most of the damage. I just had to replace the plexiglass lid, a wiring harness with some melted insulation, and a few limit switches. This is a far higher-class machine than the Epilog. Only lingering damage is some soot and melted plastic that I was unable to get off of the paint in the cutting chamber.I am trying to get $10,000 for this one. I have almost $4000 in parts in it, and brand new, they go for $35k+. The only one on eBay at the moment is a 45 watt unit going for $10,900.FilterBofa Advantage Oracle, manufactured in 2013This has a carbon filter and pleated cloth filter to remove harmful contaminants from the laser exhaustIt came along with the Trotec, but it will work with any laser.There was no heat damage to this thing, and it works perfectly.I'm looking to get $1500 out of it, but if you buy the Epilog or Trotec, we may be able to work out a discount. I haven't seen these on eBay, but the Trotec Atmos (nearly identical unit) goes for over $3000.
