i did almost the same thing for an ice drill rig (L shaped), but attached at platform at the corners with wheels. Must say this is much more simple and expandable. Awesome!
Instead of using long-running timers to retract your pistons, consider an event controller. This will let you pause your retraction without messing up the sequence.
Well with timers you can also shut down and it stops the timer time I will be adding event controllers to the printer for when the storage of components gets to 10% that way it will shut down when low on materials and when the materials are good again it will turn on and continue. That’s how I plan to use event controllers In the printer.
You should see the new design I have when I finish my 235x63x63 printer I’ll show it. Spent most the day building a new battleship today hopefully I’ll have that soon.
