    I really want to build one of these. It looks awesome! I am curious as to what materials you plan to cut with this laser.

    Awesome, can't wait to see the results. At 80W, you had better not forget to put the stock you are cutting in there before you fire it up - it'll cut through the floor! :)

    Mostly wood and plastics right now. I like to do some engraving on some metal also. Also want to look at cutting some G10 type material and/or fiber (heard need to be careful about some of that - plan do get a good exhaust system going to vent outside.

    What mirrors laser head did you use?
    Do you have CAD models for them?

    Is there a proper build sheet for this or could I request one? I am currently shopping around for a laser cutter and I think I would much much much rather build this one than buy one online from China? It looks great. If you can provide me with it whether on here or through E-Mail that would be great! Daniel.Peebles@8bitechnology.com Thank you for sharing your awesome project!!

    Just a question, how fast can your x and y axis move ???/per second

    You know I really do not know - right now it is sitting on a portable table that is not very sturdy that allows it to shake when I do move it especially the Y access (gantry) . The X access is not an issue - very smooth and it is not moving much weight. I imagine I could use a NEMA17 on that access or a much small NEMA24 - Think i have a 280 or something like that.

    Anyway, I have easily moved it add 3000mm/s (think that is the right unit). I am just going off the top of my head right now. Once i get it one the dedicated table I plan to build I will be able to move fairly fast - will have to do a video of that!

    Added my current 3D design (step export for Fusion 360) file plus a few other design files for the parts. Will add 3D Printed STL files also sortly

    Mostly Wood and Plex. I want to also play with engraving metal. Will experiment with some other materials but nothing definite right now. Oh, also foam board - got some models layouts i want to cut.

    Awesome start to the build!

    I'd be interested to see how much deflection you have over the length of the gantry. What profile did you use?

    I'm finding that my buildlog.net 2.X laser is too small with only a 11" x 18" bed and would like to look into scaling it up.

    Sorry Rich - not really understanding your first question about deflection/profile.

    As far as size - my cutting dimensions are 600x1200mm which was my my goal to be able to cut 500x1000mm so I fairly happy.

    I was wondering if you had any deflection issues along the 1500mm long extrusion. ie. When the carriage is in the middle of the x axis, are there any alignment issues with the laser beam?

    Which profile (20x40, 40x80, ect.) Did you use for your x axis.

    Thanks,

    Rich

    Oh, absolutely none. The X assembly is so light it was probably sturdy enough with just a 20x60 I have running horizontal but I did put a vertical 20x40 under it to make sure i had not flex at all! Lasers are nice in that they are so light compared to dealing with building CNC router systems in which you have all that weight to deal with! I also build 3D printers and building this laser cutter is much like building a 3D printer. In fact I was thinking it would not be hard to add a 3D Printer head assembly if I wanted. Just need a little more wiring for the head - although the length of my system may be a challenge to do something like that when dealing with print head heater and hermocouple/thermistor.

    How did you close the loop on the belt system for your z axis?
