Ed,
The Saturn 2 is a new series that is basically and updated version of the original Saturn series machines. We released it on sept 15th. See https://www.finelineautomation.com/a...g-the-saturn-2 for a detailed overview on what’s changed. We have a few that have shipped out so far that are being delivered this week.
As far as the 8020 gantries go, those are up on the site till I run out of inventory. I have a few of the 2x4 machines and 1 4x4 machines left.
The Saturn series come with mounts for the proximity switches but not the switches themselves. The Saturn 2 needs just 4 switches for both limit and homing functionality on all 3 axes. The Saturn needs 6 switches. The mounting points were completely redone on the Saturn 2 to greatly improve the functionality.
Also, stands for the machines are coming this week.
