I wanted to make a light weight, simple design to easily adjust the Laser Module height This can be made with the laser itself, so no 3d printing required. This was designed for the NEJE 40W laser but you should be able to adjust to similar diode laser modules.

    TY for this. I have a NEJE on the way. Will give this a try.

    Thats a great design! Was thinking about adjusting it with screw too.
  • Hi many many thx for the info and the file. I cut the adjust Module with plywood 3 mm. and paint it black. I use a hot glue gun to fix the screw nut. Built all together incl. air assist and and it works fine. thx again cu Steve

    Great video. Thanks for the idea. Where did you buy your laser bed from ?
  • Out of curiosity, have you had any overheating issues at all? A significant portion of the fan is now covered. I have a substantial air assist that would make up for it when it was in use...but it's not always in use lol. Thanks for the share btw, I initially had some troubles downloading, but googling how to download from github solved the problem for me entirely.
  • I downloaded it, cut some 3mm black acrylic at 100mm/m and 90%. It cut great. I may need to try it at you focal point. I had it at 17mm and the intersection of the pieces is just a bit tight. I didn't know if using a kerf offset might help or change the focus. I am trying to copy and adjust for the thickness but not getting the results I wanted.

    Very very cool idea!! I love it!!! What size bolt are you using? Length and size? Thank you so much!
  • I came here out of curiosity to see if you were using the same design i'm using and i became interested in your Laser Cutting Bed? Is that 3d printed? If so is there a file available or you just made it yourself?
  • Hi, I loved the video. What is the correct focus height you use? I can't focus my laser...I have the same one as yours. Thank you!!!
  • @albertoqc3204
    Nice video! One question. Is It a double beam 40w neje modulo ? Thank you
  • Have you found the added weight of the acrylic to effect the machine any at speed or accuracy?
