Did you have a printer at ERRF that was built with square tube? if so are the files for it somewhere?
No, at ERRF I had Piper 1 and Piper 2 with EMT conduits.
nevermind, just found it in my pictures it was conduit, sorry
Maybe it was someone next to you, I remember it had a stationary bed, maybe 300mmx300mm it looked just like a piper but had 1/2 or 3/4" square tube?
Sorry, I do not remember
