Thanks very much! I’m happy to test them. It’s better than starting from scratch for sure.

Hi Doug.
What do you use to support the Jackpot when you’re using those panels?
I printed my panels an extra 0.5mm loose, so I’ll definitely need to secure them with the screws on the tie-downs. I figure while I’m drilling I might as well figure out the Jackpot.
Thanks!
Re. panels – If you are meaning the “gantry back covers” then, I’m guess you are thinking of the Jackpot in-beam board holder / mount. I now have that in the Printables listing with the back covers, as well as photos and notes.
Thanks very much! Does one of the covers have a fan mount? Or is the fan only inside the beam?
The board mount has a fan mount on it, which draws air from the center of the beam and blows it over the drivers, out toward the end of the beam. At least that’s how mine is. I started off with a fan mounted in the cover, but as soon as I needed to lift the cover, the fan and the wires were kind of in the way.

Is this your final answer on gantry rail length.
I have been reading for days on this subject and seem to have more questions than answers.
I thought I read someware you said you had eliminated the strip behind the strut.I have an
idea to add 2x2 behind the strut and use standard y clips. And have better strut to table connection. I would use extenders. So I wonder if you could make fusion
file with the off rail side belt in the strut.I have to re cut my rails anyway, so what ever size you recommend. If this is not appropriate or in the wrong place, sorry. I have read lots of your posts and many videos much help thank you
The values you get from the LR4 online calculator are your best bet if you are starting from scratch. I was not starting from scratch, but rather working backwards from an existing table that I wanted to still be able to use. I do have a functional set up, but it’s not as ideal as if I had just gone from scratch with values from the online calculator. Are you trying to reuse an existing table or starting from scratch?

I am starting from scratch. I thought more on this setup and I don’t need to notch for the 2x2 I would just use 2x2 blocks glued and screwed in place. So calc. Says 1406mm for length. And I want to use one sheet of ply so 3 5/8 ribs can you send me the link to the ver 4 fusion file that will work for me. Thanks!
Since you are starting from scratch, please consider this post by Ryan of V1 Engineering, showing an affordable and doable way to get a full size table, without needing to resort to use of Unistrut metal rails: ~ $200 Full sized Lowrider table, Non-CNC Build
If you are wanting a torsion box design like that, I’m pretty sure Ryan @vicious1 shared the CAD file for what he did: quote from his post:
CAD - Onshape
Does that work for you?
