Dockable magnetic Klicky probe on a Voron 0.1

The most surprising part of this build is the choreography: the toolhead swings over to the right front extrusion, snatches the probe off its magnetic dock, measures several points across the bed, then drops it back before continuing. Watching a fully automated detachable probe cycle run on a Voron 0.1, one of the smallest Vorons there is, caught me off guard in the best way.



The machine itself is tidy. It is a compact enclosed CoreXY with black aluminum extrusions, clear panels, and printed parts in blue and red. LED strips fill the chamber with a pink and white glow. The toolhead carries a cowl with a small axial cooling fan and a part-cooling duct below it, and the bed rests on a printed Z-axis support block with an adjustable leveling screw and spring. Linear rails run on toothed belts with corner brackets and idlers.



What stands out most is the probe mount. In its default state it flexed at the magnet connection, and the maker adjusted both the probe points and a third adjustable magnet on the mount until that flex disappeared, calling the magnet adjustment an important step for probing accuracy. The probing routine now completes cleanly with the probe returning to its dock. The reasoning for adding it holds up too: a probe that touches the build surface is more accurate than a separate Z endstop, it is unaffected by thermal expansion, and different PEI sheets can be swapped without recalibrating the endstop. The maker finds screws_tilt_calculate and bed_tilt_calibrate very useful with it.



One thing stays open: the maker wonders why the documentation never mentions adjusting that third magnet. Worth noting as well is that the recording was made right after the probe first worked, before any tuning, so the finished result may look even better.

The third adjustable magnet is the detail that wins this for me. A mount that flexes at the magnet connection would quietly ruin every probe result, and tuning that joint until the flex is gone strikes me as the difference between a probe that sort of works and one you can trust. It also seems telling that the maker considers the adjustment important enough to question why the documentation leaves it out entirely.

How did the maker actually dial in the third adjustable magnet? I am curious whether the flex was spotted by watching the mount during probing moves, or whether it showed up as inconsistent readings between probe points. Also, when the probe points were adjusted, was that done before or after the magnet fix, or did the two changes get sorted out together?

Since the probe allows different PEI sheets to be used without recalibrating the endstop, a natural next step would be keeping a second sheet with a different surface texture and swapping between them to confirm the readings stay consistent across both. It would also be worth repeating the probing routine now that tuning has happened, to see whether the results hold steady compared to the run recorded right after the probe first worked.
