Enough said there!
Here’s what I would do: Get the machine as square as you can:
From there I would make sure that everything is adjusted in per our specs (spring tension on the rack drives, properly adjusted belts, etc)
I wouldn’t obsess over it past that… Given that it’s at a maker space where people are going to be doing all kinds of oddball stuff it’s all about learning the best machine/workflow for the job.
If you try and chase some tuning for a project/operator that you cannot predict you’ll go mad. Just make sure that machine is in spec and functioning properly, and give people the tools to check that it’s in spec. Perhaps signs saying “check belt tension XX weeks” or “grease monthly” or “check square routinely”
If you do that, the machine will perform repeatably and reliably and you can keep people focused on learning and using it for what it’s good (And not good) for by actually doing stuff.
