💡 What is the proper method to set Z-axis limits on a small CNC router?

Getting your probe calibrated correctly keeps your cuts smooth and stops broken collets before they happen.
- Flip the master switch off before touching the six wire leads to dodge nasty shorts that fry your drive cards
- Nudge the sensing tip down slow until the normally open contacts snap shut so you lock in a crisp zero point
- Jog the axis over scrap plywood first to confirm the stepper stalls exactly where the software tells it to
- Keep a handy stash of replacement plunger springs ready so you never get held up by worn contact pieces✝️
