LowRider V3 – Issue with Y Rail – Any Solutions?

Hello,

I’ve run into a pretty big mistake while building the frame of my CNC LowRider V3.

I used aluminum rulers/profiles that are 3 meters long and 10 cm wide, and because of that, I can’t properly position the feet for my Y rails. The width just doesn’t allow correct placement.

I’d really prefer not to spend another hundred euros on new rails with the proper dimensions just to fix this.

Does anyone have a solution or workaround? Maybe alternative feet I could print, or some kind of modification that would make this setup usable?

Thanks in advance for your help!

Can you just spin them around so they are outboard?

I have an LR4 and looking at mine I don’t see any reason not to.

Will the gantry roll along the Y pipe without interference if the pipe mounts are faced the other way?

Personally would flip one of the inner mounts around, and then check clearance is ok.

If clearance is fine and you have space, lift pipe up and swing it around 180 degrees (shouting “helicopter” is optional).

That won’t work. There’s not enough clearance.

You could 3d print a modified piece or a spacer. Or you could just use a wood strip.

on LR3 its not possible, there’s not enough space.

Thanks, I’ll think about it, but I’m not sure how I can make everything fit together properly while still keeping the structure solid and rigid.

Bummer.

Took quick look, didn’t see any modded ones that can work flipped, maybe I missed one, could’ve sworn someone ended up needing to do something similar before. Fwiw I briefly looked at these…

In this situation, I’d search a bit more for a modded clip that works, or design and print some. Would be neat if the roller part and clip design collectively allowed mounting clips in either orientation.

I think I’m going to move toward designing a mount for the belt holders; it will probably be easier than trying to find a solution with the Y rail feet.

What size pipe do you have? Already checked if there’s a LR4 clip variant that’s compatible with your pipe dimensions, and, whether LR4 clip has a lower symmetrical profile than LR3 clip.

Am wondering if LR4 Y clips faced with mount holes towards center of your metal box will work for your LR3.

EDIT: Nope, I can’t see that working. Just looked at my LR3, it’s been a while, the LR3 front roller’s tight downturn doesn’t have room for a LR4 clip (because of where the front roller’s bolt mounts to YZ plate).

what is stopping you from moving it over???

Agreed, can you scoot the Min side a little so you can attach the rails how you like?
