My LR3 build starts here :slight_smile: I had most of the parts ordered and printed upfront. It took 2-3 weeks to print the parts and receive everything from all the online shops. I spent something like 470 EUR for the parts excluding the steppers, as I used the ones I had from my previous cnc. […

Very nice build! I’m interested in building a LR3 for the exact same purpose. Printing the parts at the moment. Regarding the original topic of this thread: how did you make it taller? Can you share the files for the modified plates? What size rails did you put on it? I’m also curious: what’s your…

I think @SupraGuy had the first taller mod. Hey Dan, where did you hide those drawings? :smiley:

Also, if you are building a machine for the exact same purpose, do yourself a favor and make it possible to lower the stock to about 100mm below the table level. It will make the machine more stable and you will be able to get away with less Z travel. Very tall YZ plates = waiting forever every tim…

I use the tallest YZ plates shared by @SupraGuy , I think they have 300mm openings which gives me 230 mm of Z travel. I’ve never needed more than 110mm Z travel so far, but my boards are really small. For a larger surfboard or wingfoil board you might need 130-160mm Z travel.

LR3 Adjustable Height Hardware Development

I increased the height of mine by 50mm, so I moved the screw holes up by 50mm and the Z stop mount the same. This makes all 3 beam screws available near the top of travel. My first shot, I left them alone and it’s still doable, but you can’t reach the top screw at the same time as the other 2, so I needed to move it all the way to the top for the one screw, then lower it until I could get the other 2. Yes, I needed to adjust the perimeter shape. Kind of a shame, it means that the toe wheel/rolle…
