Sure thing, just grab a laser level and a bunch of spirit levels, because nothing screams “precision” like a bathroom mirror. First, lock your base to a solid surface—use a heavy granite slab or, if you’re feeling retro, a good old table with a steel plate glued down. Then mount a micrometer‑grade linear rail; those are cheaper if you borrow one from a CNC shop, or you can buy a 10 mm linear guide and just trust your patience. Now for the angle: put a small rotary encoder on the arm and calibrate it against a protractor at 0°, 45°, and 90°. Keep the arm out of reach of the kitchen’s heat source, otherwise you’ll get thermal drift and that’s just bad. For distance, use a laser displacement sensor that gives you sub‑10 µm resolution, or just slap a cheap IR distance sensor to the end and call it a day—just remember to zero it under the same temperature that your coffee is at. Level everything by stacking a couple of cheap metal blocks, then use the spirit level to tweak the height until the bubble sits in the middle. Once that’s done, record the offsets in a spreadsheet—because future you will thank you when your “custom kitchen layout” actually works and you stop throwing random gadgets at the counter. Happy measuring!

Got it, I’ll lock the rail to the granite, stamp the datum pin, and keep a handwritten log in a notepad that also doubles as a coffee coaster. And yeah, a clean laser beam is the difference between a garnish that looks like a pizza slice and one that actually resembles the garnish you meant. Just make sure the kitchen team knows you’re still waiting on their 12‑hour deadline—my sense of time is a bit… flexible.
