Has anyone tried to build the Lowrider as a vertical CNC machine? I’ve been looking at things like https://www.buildyourcnc.com/Item/cnc-machine-greenLean-v1 and http://www.maslowcnc.com/, but I’d really like to use open hardware for this tooling so that I can fix it when/if things go wrong. Maslow almost fits that requirement, but they use custom (i.e. impossible to source) motor encoders and driver boards. I’d really love to use standard Cartesian movements if possible (just for the sake of precision).
As far as I can tell, the only thing that’d need to happen to the lowrider design is a bit of modification around the rollers (so that they can support a vertical load instead of a horizontal one) and counterweighting the router carriage so the steppers don’t have to fight gravity.
Is this a reasonable thing to do or am I totally off the rails here? My goal is a full sheet CNC machine, but I cannot dedicate an entire garage bay to it. I can definitely spare a dozen square feet for a vertical machine, though.March 15, 2017 at 3:46 pm #29603
We all hoped it was possible, I think it would work as is with small counterweights. I just don’t have the room, my garage is very short.March 15, 2017 at 3:47 pm #29604
Not sure how much of an angle though, 90 is out of the question but I would say pretty steep will work.March 15, 2017 at 7:35 pm #29619
It rides along the edges of the table, so if your table could be two sizes, then that should work. I’m still in the progress on mine, but I plan on using about 40″ most of the time, then expand it to bigger by moving out the car, and adding some more surface.March 15, 2017 at 9:03 pm #29621
Alright, I’m thinking I’m going to do a “conversion” from my MPCNC to a Lowrider (just ordered the missing parts that I can’t source locally – basically everything but some nuts and bolts). I think I’ll get it working in a normal horizontal configuration first, and then if that’s successful, experiment with making the entire setup vertical. At least with the Lowrider, I can disassemble the thing somewhat and gain back that bay in my garage!
Thanks for the input folks!March 16, 2017 at 8:31 am #29639
Think seriously about 45°, 60°, etc. before you try 90°. You can save a lot of floor space without going all the way.March 16, 2017 at 8:56 am #29643
Yeah, definitely wouldn’t want to do 90 degrees. I’m leaning more toward 60-ish. Even that reduces the footprint of a full sheet very substantially.March 16, 2017 at 9:10 am #29646
how would you do the counterweights?
