MPCNC Style Delta Printer

Hey All,

Putting out a thought I had about the rail and bearing styles of the MPCNC being applied to a delta style printer, possibly in the sizes of 2-3 metres tall (6.5 - 10 foot). Care to discuss?

There is one on thingiverse by Geodave,

I am sure it works but the will have a bunch of weight to them so that will drastically reduce your accelerations.
