90W, 900x600 Home friendly CO2 Laser DIY build.

[Oleksandr Masliukivskyi]

Greetings, dear friends . I am starting this thread today even if i have nothing to show yet, just for the history. Yesterday i finally received some parts from China (100kg ). So - YES - this is for real now!

Here what we have here:

-90W SPT TR90 laser Red dot tube - never saw anyone using one yet. Why?
-S&A water chiller 5200AH;
-Ruida RDC6445G;
-Full set of HIWIN linear gantry;
-4x Nema 23 no servo (XYZ)
-Z axis gantry;
-Blade bed;

I am going to buy everything else later, after i have the finished enclosure done in Fusion 360.
This is a new program to me, though i am 3D Generalist and worked with many other 3D software before.
Fusion 360 is very easy to learn and pleasure to work with. I expected it to be more painful and happy to be wrong! Here is what i already can do after only 1 week of learning:

My learning source was some Youtube lessons (they are very repetitive), and official Fusion 360 learning sources (they are too boring). So i learned it just by making stuff i need to make. This is the most effective i guess. Just learn interface and after that - read menus and search google if you stuck. Youtube is good for that.
I consider i am done with the learning part:) Next - to convert everything in 3D!

Have no idea how much time it will take. But my excitement is through the roof. Let's see?!

Welcome Oleksandr. Looks like you ready to have fun and get to assembly.

[Tim Mellor]

Lots of bits to unpack for you

Fusion in particular when you get a proper handle on structure of components, bodies and drive the timeline properly works really well. Nice detail on the Mirror mount too

-90W SPT TR90 laser Red dot tube - never saw anyone using one yet. Why?

This is a fairly new development but it seems like a good thing. I am a proponent of combining lenses to integrate the red dot but this seems like a more elegant solution. Please post your thoughts for us when you get this machine up and running. Gene

3 years ago I started this project and successfully abandoned it since then, as I always do. Showing you its current state as an official goodbye. I thought one day I will finish it, but no. Stop lying to yourself Oleksandr, just move one already. And i am moving on. If anyone interested - I have all the components except extrusions, collecting dust for 3 years lol. It supposed to be silent (with thick walls), all in one system (chiller and air compressor all inside), no motorized Z (but I have ordered lift components too, just in case), since I supposed to cut only acrylic sheets, with inbuilt filtering system (3 step filtration), 90W with red laser dot, all designed to be used in office environment. Ambitious?
If anyone interested - I am selling all of this in Ukraine.

Admitting 'defeat' [not really but it is a mental state that is hard to avoid] is a hard thing to do but sometimes you have to give in to reality. At least you are not very proficient with Fusion 360, which is a skill that will last a lifetime. Good luck with selling your parts and your life in Ukraine, I am committed to support for Ukraine however I can.
