Sweet Post! Now I want to get one.
Thanks for sharing!!!
Hey there! I’ve got a question if you have a second. I’ve got a k40 machine and would like to upgrade to a 50 watt tube. Do you know if I’ll also need to upgrade my power supply in order for this to work properly?
Did you run the k40 on a 50w tube without changing the psu, how was it i’ve been trying to find out if this would work myself.
LOVE K40 Whisperer!!!
Hands down the best replacement software to use.
Very easy to understand settings and use.
There a number of k40 brands , could you say which is the best choice?
Also, is inkscape/k40 whisperer difficult to learn?
Hi I am unable to download your software
Decent Photoshop Script
Quick question. I purchased a K40 last month (December) but it arrived with a cracked tube. The company refunded the cost of a new tube, which was easy to replace. Finally got it fired up, but now it won’t quit lasering. It won’t engrave, it more gouges, even returned home, powered and stayed powered until I pushed the “laser switch” off (defaults to on position, “laser test switch” does nothing). Any ideas or advice what to check/look for or where to go to ask? Users manual doesn’t help, and the seller put me on ignore mode. Any helpful pointers would be appreciated.
The baase machine is a great place to begin. I have purchased 2 new 40 w systems and plan upgrades before I even plug them in, I am wondering if upgrades applied in this condition if it is a smart hing to do?
Hi software works great
If it starts working after the electricity goes out of the same area
I’m planning on purchasing a k40 engraver to be able to engage my logo on my handmade duck calls.
I was wondering if I would have to have a cylindrical attachment or will it grave with with out one on that small of area.
What will be the best setting for a plexiglass 2mm with a K40 laser?
Try the acrylic settings listed because plexiglass just an acrylic namebrand. Lexan is similar but it’s a different kind of plastic called polycarbonate. Be sure your ventilation is good when cutting these.
Acrylic, Plexiglass = https://en.wikipedia.org/wiki/Poly(methyl_methacrylate)
Poly Lexan = https://en.wikipedia.org/wiki/Polycarbonate
We’ve got a set of Co2 compatible glasses here which are actually manufactured buy a Co2 laser manufacturer. It’s wavelength is k40 compatible and most i’ve tried to source have not been. They’ve just been tinted glasses :S.
K40 Laser Safety Glasses
As for the honeycomb bed, It’s up to you really. You don’t really need one, but if you do manage to get one it will help with smoke dissipation and it’s a good stable platform for your work.
Personally I didn’t have one for the first 5 months havin my K40
It has tips and guide for whisperer (which I actually use) unfortunately I havn’t written any Inkscape tutorials as of yet but feel free to ask away on the forum and I can answer them there,
I have a job that requires me to cut 2mm(5/64″) birch aircraft plywood. I am finding that 1/16″ aircraft birch plywood, is really difficult to cut.
I do not have an air assist, as of yet, but, will have it set up by July 12th.
I ran over 30 passes, @11% power, and 15mm per second, it barely made it through the 2nd layer. I tried increasing the power to 30%, and i turned my back for a minute, and it actually caught on fire.
What am I missing on this? I have read, and seen on YouTube, that a setting of 50%, WITH AIR ASSIST, would work. Am I correct with this, or what setting would you suggest.
This project is very important to complete. I have a few weeks to do so, so I thought I would head off any problems, before I get myself in to deep, and it doesn’t succeed. I have several hundred dollars invested in this, and stand to make a decent profit, with a bit of work to make it happen.
Many thanks in advance, for your time! I anxiously wait for your help!
Hi Taz. Make sure your focal length is spot on (distance from lens to your timber) it’s normally 50.8 mm on the k40. Being a 2 mm plywood that would be 51.8 to the centre of your wood correct? Have a look on YouTube and search for ramp test for laser to find the focal point to get a crisp cut. If your focal point ends up being in the centre of your wood you should be able to cut in 5 passes at 20% power no worries. Also check cleanliness of your lens and mirrors. Sam
These power supplies are very basic and can be repaired easily. When they break down, it’s mostly the big output schottky diodes named FR307. Just measure with an ohm meter in both directions if there is a short (then it is defect).
You can buy them from Jaycar $0.39 and just cut off the leads from the top at the existing part to make a swap easy otherwise you have to pull the PCB from the frame which is a lot of work.
What are the percentages for acrylic instead of ma?
I would like to replace my laser head set and upgrade the mirrors. Can you please suggest a good lens and mirror size? The standard the come with the machine are 12mm for the lens and 20mm for the mirrors. Is the 20mm lens better in performance than the 12mm stock? I normally cut 3mm and 6mm ply with my machine.
Thank you for your help
I am looking for a laser etcher for etching names on fishing pole handles. the handles are round and the name would be 5/8 inches tall and up to three inches long on the side of the handle. Could you recommend a laser that would take care of that process?
