tips on FOCUSING laser for BETTER cutting (K 40 laser cutter) k40

- Keeping the laser focused and the mirrors and linens clean is extremely important. It’s a tedious process going back-and-forth with the mirror adjustments and verifying all four corners of the table are zeroed in. In the video I go through the process I’m getting the focus correct. I use masking tape to see where the lasers actually hitting.

This video is not about FOCUSING, but rather ALIGNMENT. And, unfortunately, it is not doing that right either.
Dude buy some nail clippers. Oh and you dont start aligning from the second mirror, you start at the first.
Hello, I advise you that the outlet hose of the cooling water is always under the water level, so when you turn off the pump no air will enter the tube.
Dude, use minimum power for mirror alignment.
This guys girly finger nails are freaking me out. Time to leave
it does not matter if you are hitting the middle of the first. Second or third mirror. Only thing that matters is if you hit the middle of the lens. If the tube is not exactly aligned or one of the rails are not completely square you will never hit the middle all over. Try to hit the same spot both close and at the end on all position. If its to the left. Right. Up or down from the middle is irrelevant. At the last mirror. You adjust the beam to go to the middle of the lens. Test this by elevating the cutting suface aligned with tape to the laser head. Make a square around the jead on the tape. And lower the surface down to cutting hight and make a pulse. There is a really good video on this on youtube.
Oh.. and buy a flow switch instead of having the outlet tube above water level.. this just makes it more lilely for your pump to pull in air.
If you adjust a beam the distance to the target mirror has to be max. What you do is just not precise as understood with a tiny bit Pythagoras. Long distance + small missallignment = visible offset. So set Axis FAR when doing this. Means Laser head to the right.
You can adjust the mirrors all day long, but if the gantry assembly is out of square (which is highly likely on the K40) it will never make a difference.
Yes. I need to square my fantry but i dont know how. Do you know a how to video to squaring the gantry?
Man I can’t even watch this with those finger nails.
Unfortunately if it’s that bad in all the corners than your gantry isn’t level and no amount of tweaking will make all the corners the same
Hello. Excellent video but I haven't been able to center the laser on each extreme. When it is centered on the left top, when I move the Laser head to right top, it is not properly located. I tried it for an hour unsuccessfully. . Can you help me with this? I also tried mirror adjustments from the main mirror behind the machine, the first one the laser hits. I got the same problem. I appreciate your help.

dont go by this guy he hasnt a clue what he is doing
perfect example of how not to do this... sorry man, but if you adjust the same mirror with the last mirror in different places, you're just chasing your tail. The gantry must be out of alignment if you're getting that much play just moving the 3rd mirror on the x axis... good luck.
Do you know how to align the gantry and point me to a video or something like that? My gantry is waaay out of alignment
First thing to do is align the mirror at the tube, that is the best starting point. the beam should be dead center secondly you should align the left mirror, at the back and the front. check the back position again, because the front positioning effects also the beginning position ever so very slightly. and third and last the mirror on top of the lens in left and right position. again after the right position recheck the left position again for the same earlier reason mentioned. ALWAYS start at the beginning
by the way, the very first mirror should be dead parallel to the metal glider if not , you'd have to move the entire mirror, not just the set screws. that goes also for the second mirror and the third, just to be square
even I had it not quit correct, here is a link to a good method

kind regards Hans
What's up with the dudes nails
So many things done wrong in this video, do not do not do the same as he did .
Have you better option? Because now I have this problem...
For proper explanation watch John Cabrer video 😂
Can you repeat that? All I heard were fingernails.
Wrong method.
