The rig…
Stalled for a couple days, waiting for resolution surrounding damage during shipping. Ultimately the seller and I were able to come to a resolution quickly and repairs to damage began.
With most visible misalignment etc taken care of, plugged in machine, tuned and tested first few prints using PLA I had lying around for old Makerbot machine. First few were just frizz but without much fuss a few successful prints came out.
Prints…

Delivery…
Working on air pressure system this week.
Brass fitting on canister is bent, maybe should be replaced? Note from owner, Brass fitting is PRV. Pressure release valve.
7/25 Compressor arrives, look great, quiet
7/29 Purchase new blow off valve @125psi via Amazon – Ultimately this part will cause me a lot of headaches because it is cheap poorly made item.
Clay…
Began researching,
Via JK
Red clay has small platelets -> too sticky -> x
White clay has large platelets -> less sticky
Also too much texture is bad as it also adds friction
JK goes into detail, but ultimately as he is using UK and EU source, I will buy something comparable and readymade from Laguna
JK also notes a whole bunch of shrink rates, while they are useful, I will need to test on my own clay body, however, he notes that shrinkage is more dominant in the vertical direction.
