Anyone else disappointed with the JTech 2.8w laser module, namely the cutting capablilities?
The website states it can cut both 3mm ply and acrylic. I have only managed to cut glitter acrylic and the laser shielding supplied by JTech. Anything else, forget it. As far as the ply goes, not even close.
I have tried many different variations in power, speed, passes etc, but not very happy with the results.
Only claims to be the 3mm of materials with slow and many passes. It’s the higher end lasers that will cut materials fast because of the co2 or fiber lasers that are out there that are made for it. For a engrave laser it’s the best around I think since it’s cheaper and your not buying a machine other then the x carve to make it move.
But even on their YouTube videos and on line they have stated it’s with many passes and won’t cut anything that is thicker in size. For foam or thinner pieces depending what it is will cut but it’s more of a engraver as it’s stated on their website.
Have you checked your focus and Z axis distance? You need to really fine tune this to the optimal distance and also focus, i have cut maple veneer with two passes with great efficiency and quality. I have also cut some acrylic but was a long time ago, so I don’t remember.
Try checking your distance first, then your focus, and then make sure you are outputting full power.
Yeah plus others have made their own frames at a smaller price range also. I’ve seen on open builds it’s cheap for their laser kits also. Could turn it into a nice plasma table with the right controller and water table welded up.
I bought a $400 forty watt China laser and it has limitations too. I’m definitely getting good results for what I use it for but I’ve had to modify it get what I want. All said I’ve spent around $750 total for a 10”x12” work area. I did a ton of research and knew I’d need to spend more on mods before I bought it. No regrets and runs great.
The key to success is thorough research before the purchase.
I’m not faulting anyone for anything. All I said in a nutshell is that I didn’t purchase the jtech because I needed a 40W laser to do what I needed to do. I made my decision based on thorough research.
Sounds like jtech has some explaining to do?
Fun facts based on my k40 laser research:
Just under 40% of the k40 lasers purchased do NOT work or have serious flaws when they arrive.
Critical to select a reliable seller.
Controller boards are unpredictable and may fail or burn up.
Software works but does not get good reviews.
Expect the laser tube to fail sooner than later.
Expect the power supply to fail or be under powered.
So based on my research I bought the machine anyway. I knew what I would need to do and how much it would cost to fix any issues found. I’m $1,750 ahead based on my decision not to buy a $2,500 name brand laser.
None of my information came from the manufacture or sellers website.
my K40 tube failed literally yesterday. Well something broke off, so I consider that failing…
I know of people that cut 3mm ply with a diode laser in several passes. It’s not unheard of, it’s just very impractical.
That and companies tend to oversell their product. Or at least stretch the truth somewhat to their favor. That’s why you should always look to more objective sources other than the seller.
From what I’ve read, Jay seems to be a pretty stand up guy and backs his products. If you are truely dissatisfied I believe that he would try to work out a resolution or compromise that will address your issues.
You might try and contact him to see what he can do for you.
I want to chime in and say not all 3mm ply is created equal nor is acrylic.
Even with my 60 watt CO2 laser, I cannot be sure that I will get consistent cuts on anything!
What I mean is that I always try and use the least amount of power to get the job done. When I am dialed in on a test piece of the same material, all is well. If I change to a different piece of the same material from a different source, I might not have exactly the same results.
Yes I can always increase the power and cut through anything but the end result might not be pretty!
