LowRider 4 CNC

The LR4 DIY CNC that can handle full sheet goods and smaller. Build it to fit your needs.

Welcome to the LR4, the LowRider CNC v4, AKA the most productive you can be while still scrolling on your phone. Let the robot do your dirty work while you scroll away and keep an eye on it working.

This is a full sheet capable CNC router. The goal is to provide an inexpensive platform for people to use for their specific needs.

The size is up to you, make it any width or length you need, the smaller you make it the faster it will be.

Use any tool you want, provided it is 69mm in diameter or less.

Any control board you want with any firmware, I highly suggest a 5 driver board with firmware that can use dual end stops to auto square. Marlin, GRBL, FluidNC, Smoothie and RepRap firmware are a great place to start. The Jackpot CNC Controller was purpose built fully featured, expandable and a great price.

You can buy from the V1E.com Store or self source. You can pretty easily keep the entire build under $800 USD. Far less if you have a 3D printer to make your own parts.

All the details, lists, and instructions can be found here, in the V1 Engineering Docs.

Looking at about 2.7kg for a full sheet build's worth of prints, any rigid filament will work, but PLA works great, fancy options would be PET-CF/GF or PC-CF/GF.

Extra special, thanks.

The Beta team put in months of effort helping to refine and improve all aspects of this design. Countless prints were made only to be scrutinized, revised, and remade. Debates were had, caps lock was used, it was not easy for any of us, but it was very fun. Extra thanks to Peter H, for helping with the looks and shape of it all. I am sure I can speak for the whole team, we are proud of what we accomplished, and I am confident it will outperform your expectations.
