I got tired of the fight keeping an NFS mount happy because it often wasn't. Exact same hardware but sshfs is a breath of fresh air as it Just Works. Every time! So thats what I'll setup as data & gcode storage once I am in a position of needing it. The configs tree, once running, won't be edited very often so it could live on the u-SD. Or should I just point the sshfs link at a Pi-LCNC located on my home net, maybe even on this machine as its not drive space crowded. And that would be backed up by amanda every night. I like that. I could take the 60Gb SSD out of the Dell I am playing with now IF the Orange Pi has a sata, but I'm not sure it has a sata. Its been shipped but no clue where it is. I have 2 reasons for doing this, first being that its so small it will all fit on the door of the motor driver box, which s/b swarf proof. 2nd of course is that I'd like to learn something about this shirt pocket sized magic, and with the 7i90HD at just a few shekels over $60 shipped, cheap enough that I can "play with it". Speaking of playing, I still haven't a clue how fast I can ask this motor to spin. I set the max hz to 150=4500 revs, and left it spinning for about 45 minutes, watching the temps & listening for unusual noises. The rear bearing warmed up about 10F, but dropped back to about 7F after I picked up a hammer and pecked on the rear bearings socket in the end bell, but other than a rather pronounced siren-like howl from the fan blades, and a just detectable out of balance rotor, also worse at the rear, it sat there and ran like it could do it for 50 years. And its at least 40 yo already, out in the weather from the looks of the paint. Once in a blue moon I might come across a good deal. I did not expect the torch to cut bolts would come out and go to work when I offered him a $50 bill for both of them. But it did, like he was hungry. :) My once in a blue moon for this year.
