    Thanks for your comments.

    Yes, it was twelve years in the making. But people aren't building kits much anymore. They buy prebuilt cheap Almost Ready to Fly models (ARFs) from China. The...

    It seems to be an electrical problem rather than a recharge situation according to PhotoVac. That brings into question the power supply and even the controller. I'm not set up to diagnose that. I did...

    I have looked into several Chinese laser distributor companies and found that the reputation of some is really bad and one is accused of being totally fraudulent. None of the ones I mentioned before...

    That kind of thing is exactly what I would like to do which is why I am looking into Bell Laser in Seattle. They offered to buy my unit too. I still need more information on what they have but it...
  5. So it looks like I need to finally replace my ULS 25ER

    As the subject says, I am probably done with this unit. It was cutting really well yesterday and then the power just trailed off to something like 10 % power. I suppose that it is the tube needing...

    Dan, I use AutoCAD 2000i not Coreldraw. Mr. Hart was the person that I dealt with. The hardware is pretty solid but their support after the sale and their claims are not so much. I have never had...

    They have a video of a 25ER cutting a spiral on paper that is super fast. I think the motors and belt system are capable of handling at least some of the faster speeds but I think that they must have...

    I can't give an objective answer to that since I don't have a recent system to compare but I can say that my system allows me to cut an average kit with 250 parts in four hours when it used to take...

    I bought one of their units to keep my ULS 25ER laser running after it's controller failed and I could not get a repair that was guaranteed to work. They billed it as being able to be installed in 30...

    Do these Chinese lasers have enough accuracy and reproducibility to do multiple passes? I cut thick balsa parts for model airplanes and often make 4 passes to cut through a hard section running...

    I noticed the issues that you have described but had no idea that it was the same machine. I think it must be. I don't have access to much of my old electronics gear as much of my old shop had to go...

    Thank you both so much! I have really been scrutinizing these systems vs another overhaul of the old ULS. Sounds like the Asian machines might just have a way for me to proceed. Now, I have to...

    Scott,
    The Trotec machines seem really top shelf but out of my price range.

    Rich, I have the tabs already in the cutting file in DWG format. So what you are saying is that RDCAM allows these...

    Open paths in RDCAM etc

    I'm researching the Chinese lasers for a second laser. I have read that RDCAM requires closed paths in the .ai files that are sent to it from AutoCAD and CorelDraw. My ULS allows open paths to I can...
  15. Thanks all for these valuable insights. I'm...

    Thanks all for these valuable insights. I'm passing on the used laser and will continue to look for alternatives. Actually, I am so used to the ULS way of doing things that I would really prefer to...

    Thanks, Gary. I did manage to find the manufacturer of this model and it costs $5000 new FOB I think I'll pass. I understand the problems with used lasers too. I got lucky in that mine was...
  17. Resale value of Chinese laser cutting machines

    I am in the process of looking for a replacement laser for my aging ULS 25ER. It's been a super working machine for three years now but I know that time will eventually force me to buy a replacement....

    Not fulfilling the contract is very serious. I have communicated with Robert in the past and considered his company to be the first stop when my aging ULS 25ER finally stops working and I need a...

    PhotoVac does a great job at reasonable price and they told me that they do the recharging for Synrad so your tube will likely end up there anyway. They recharge Coherent too.

    I didn't make this up. If you go to youtube and search for "diode laser cutter" you will see prototype systems already working that cut and mark wood using 808nm IR diode lasers mounted on a...

    There has been a development in that area just recently and a demo laser cutter was shown operating. I lost the link but I do recall that it cut wood.

    Check out Osram Opto Semiconductors. They...

    I think it is only a matter of time before the new generation of high powered semiconductor lasers will be fitted to laser cutter/engravers. They probably could be fitted directly into the lens...

    R/C Modelers use CA glue primarily for balsa parts and switch to 5 minute epoxy for lite plywood. When they have a wood stained finish to do such as a stained and varnished sheeted fuselage, CA has a...
