I’ve been following Ryan’s work since the MPCNC was released and I must say, I’m a big fan! I printed all of the parts out for an MPCNC last Christmas and gave them to my brother, but he hasn’t gotten around to building it yet…
I’ve finally decided to take the plunge and build the Low Rider instead of just reading about it. (Only about 26 hours of printing left to go!)
I do have a couple of questions that I haven’t been able to get complete clarity on… Does someone have the cut dimensions for the steel tubing to create a full 4’ wide working area? Also, what’s the general consensus on tubing length for Z rails?
What is the current favorite way of building the Y rails? It seems like 2x4s/2x6s would be too wavy and subject to warping to work very well, unless I’m missing something?
Thanks for the great work on these machines!! I’m really looking forward to getting this guy running.
Y rails are up to interpretation. The main thing is usually people use the large machine to cut all the way through sheet material. If that is your main use, the Y rails do not need to be very accurate. If you have another use you might want to pay more attention to how accurate you can make it. I honestly just slapped mine together on the flattest surface I could rig up just for the build, and it actually came out pretty good after screwing on a top and bottom surface.
