My mill (X2 CNC if you're curious) came with a 24"x24"x3" granite surface plate. So this thing weighs close to 200 lbs. I moved it by myself last weekend using a sling made out of ratchet straps and it was wildly inconvenient and probably pretty unsafe.
Since I'm a college student I move around a few times a year at least and I would really rather not deal with the surface plate since everything else in my little portable machine shop I can move on my own. So my question is, how necessary or helpful is it to have my mill on a granite surface plate? I'm not doing anything wildly precise, .001" is probably the tightest I could possibly hold on that mill and I don't anticipate ever needing that precision for my projects.
How many of you set your mills on granite and how 'bad' is it to not have it on granite?
