K40 Laser table

I’ve seen hundreds of different K40 table projects: adjustable, non-adjustable, 3d printed, welded, improvised, motorized etc. I just wanted a bed easy to adjust every few days, stable and attached to gantry rather than to wobbly bottom. Here we go: few aluminium extruded profiles, 4x M6 screws, 4 springs and I have a bed that does what and how I need. I can remove slats and only leave them where support is needed – that allows me to have clean, tidy cuts.

  1. Hey just wanted to say awesome job on your K40 mods! I am thinking of duplicating your bed design which I think is great. One question, how do you make sure all 4 corners are adjusted to the correct height when adjusting?

    1. Hi Dennis, I use pre-cut measure. I just slide it under the laser head in the corners and in the middle of the table to make sure adjustment is right. I have adjustable head now, but still no time to install it.

  2. This slat design is impressive. The only thing I would change is the 2 bars at the bottom. I would move them to the very edges so you can still put a rotary Y axis in there if you choose to at a later date. I may have to copy this idea.

    1. If I was to do make it again, I’d rather have the table hanging from the gantry, attached somehow on left/right beams. This way it would be easier to completely remove it or replace with a rotary. Since then I’ve also seen people using (hack)saw blades for the slats. I’ve stopped modding my K40 years ago, hoping that I’ll have enough time to build a laser cutter/engraver from scratch. Well, hopes…
