Fiber laser focal height tool

thingiverse

This is a bracket I designed to mount to the head of my 50 Watt Raycus galvo fiber laser. There are definitely some things that could have probably been done a lot different, but it works great for me. Be prepared to have to use a few drill bits to make the holes fit, as I made them a bit too small on the design so that I could go in and make the diodes hold tighter (just my preference). So basically what you are going to need is 3 of the laser diodes I am including pictures of, and 3 of the nuts and bolts, along with a clamp of some sort for added support if you want it to be just like mine. You will also need a 5 volt power adapter, a small amount of doorbell wire, and soldering skills. So what I have made here is a diode holder that goes around the head of my fiber laser, that when raised or lowered, causes the beams to not line up, signifying the incorrect focal height. This is just an add-on to what a lot of the other fiber laser come pre equipped with. This makes it so much easier to find the proper focal height, vs having to take out a tape measurer each time a new height product is placed on the build plate. It works GREAT, but like I said, could probably use some better improvements on the design from developers a bit better then me out there lol. Simply align the dots once at the correct focal height, and lock down the bolts, and never have to touch it again. Hope it helps everyone! Been a fun project, but I am glad it's over with now lol. Print this at the provided angle, and use tree supports everywhere. The diode holders can be printed with no support.
