I wouldn't call it a trick, but if you just let the conveyer make some extra miles before delivering?

That level is actually glitched I think. The inputs don't match in frequency. Usually if the output requires, for example, 10 stone and 2 satelites, then by the time the 10 stone has come out, the 2 satelites are done, and then then the input repeats - that's 1 full cycle. On this level, you need 4 computer units, 2 lever units, and 1 corner piece, but at the end of the first cycle (as in, both the 2 lever units and 1 corner piece is out, and the next ones are about to print) the 4th and necessary computer isn't out yet.

EDIT: I spent ages trying to figure out what the hell was going wrong, and I just realized. The game wants you to complete the puzzle with 3 computers. Using 4 is actually wrong. Fml.

A trick I started using to slow things down is using 1 grav lifter with a floating upside down conveyor on top. That can queue up several parts vertically while waiting for other things to reach a specific destination, and it's only 2 parts. to replace 1 belt.

On another level, you can make a set reset latch using pusher who push a "cable" ( the cable has to start on the air to not be attached to the ground )

With this technique you can basically do every puzzle at max input and make each part waiting others to never have synch problem.

The most fun for me was trying to optimize some hard puzzle to make it low on cycle or footpath xD

After being super proud of one of my solution, i went to youtube and see GRAs, then I quit.
