Hello everyone,
I recently bought the lowrider kit and can’t wait to start building it. I am currently in the process of printing the parts and sourcing the conduit. I have a few options available to use as conduit.
The build will be for a full sheet. My thinking is that the aluminum is better since it is lighter and won’t sag under it’s own weight?
Any help is appreciated 
Kind regards, Clim
Don’t use aluminum. it can’t withstand the force of the bearings pushing on it. It’s will deform to much.
Leuk om een Nederlandse LR3 er bij te krijgen!
Agree, and 2mm is oké
Have a look here, got my metal from them and happy with it (they are located in NL)
Thanks for the advice, will order some tube today. I will try to keep this post updated with my build process!
Got some 25x2mm stainless steel tube from my local steel dealer.
Only some small parts are left to be printed. Still waiting for my parts to arrive, they have been stuck at customs clearance for a week now 
Just found out i accidentally printed the core with 30% infill instead of the recommended 35%. I don’t think this will cause any issues?
Looks good!
To be honest, I don’t know if the 5% will cause a big difference?
Just try it, if it breaks you can always print a new one!
Started building today, assembling everything was an absolute blast! Got as far as getting some x and z movement today. Need to build a table now so i can start putting it through it’s pases and testing everything 
Thanks @vicious1 for creating this wonderfull machine and making it all so accessibel.
Some images, aa you can see it is far from being done but i’m happy with what i achieved in a day.
For the yz plates I had a piece of 6mm mdf laser cut at my university. Then used a copying bit on the router to make them from 12mm mdf. Worked well from what i can tell.
Almost there!!
Lot’s of progress. Made a table, and got to work. It took me a while to figure out an issue i had with my z axis moving down during the crown test. Turned out i had to reset the coordinates and that fixed it.
That table is huge.
How are you supporting it?
Are you going to sheet the top and bottom to create the torsion box?
Yes both top and bottom have a sheet atached to it to create the torsion box. It is pretty stiff but i do need 6 legs to support it well enough. It works good enough i would say.
Just done building it, only need to put the strutplates in. And now I see don’t use aluminium tubes Well don’t have anything else right now, I will see how these perform, always possible to replace them in the future.
Located in Lelystad.
I did exactly the same, lasercut a thin template and used it with a handrouter to cut the side plates, big ones in MDF, smaller ones in 6mm Trespa
Let us know how it holds up! I think it will probably hold up decentrly enough
I used aluminium tubes on my MPCNC because that was all that was available in 25mm here in NZ at the time and there was no 25.4mm version back then.
They’ve flattened off where the bearings ride, but not to the point where it has introduced any issues. I suspect I need to run mine slower than if it were steel tubes, but the stiffness difference isn’t as stark as it’s made out to be, in my opinion.
It’s always possible to shrink the gantry if you want a faster machine, at the expense of area.
