Hi Goldtop,

Yes, CNC machines can be pretty finicky and expensive quick, but at least you can sit back and relax while they do the work. ;)

I did do some quick FEA on the rail, and found that it's actually fairly stiff for my purposes. Here's the test if you want to look at it. I'm thinking of using larger rails in the next few iterations that are going make this machine even more ridgid, since the material cost per food is only around 1 or 2 dollars per foot.
