First of all, your room is awesome! I have enjoyed watching your progress.Well this weekend was a lot of work without a lot to show for it. The printer filament shelves are done and I'm giving them some cure-time before loading them up.

I also got a little more of the resin side set up, but a Wham Bam flexible magnetic build surface is to be installed before the first Saturn test print. The accessory adds 2.3mm thickness to the build plate and can damage the printer if not accounted for. Some people simply attach the plate and re-level the printer (which may work, but Elegoo doesn't recommend this). Some people use a Z-stop extender which can be found on Thingiverse, but after consulting with Elegoo they've recommended to me the optimal way to modify the printer. I'll need to design a part for printing on the Pharaoh to implement Elegoo's suggestion.
The big news for me is there's now "auxiliary power" on the workbench for other devices:

Next on the agenda is getting both printers set up and calibrated, which means designing that custom part for the Saturn.
For your Saturn:
With resin printing (like most things), you will get 50 different answers to a single question. I just re-leveled my built plate after installing the wham bam plate, and I have seen no issue. You may want to consider protecting the LCD print screen. I bought a kit from Mach 5 (Mach5ive) but there are other solutions out there. One other thing to look into before you start is the resin print settings. There is a FB group that has good info on this. Its a great printer once you get it dialed in.
