Servo ABL Probe Linear Plunger

[TechMasterJoe]

a critical point for any of these linear probe movers is that they have to have a solid repeatable stop at the bottom. relying just on gear positioning or a servo arm to hold the probe in the right place will not be accurate.

agree BUT

i use an inductive probe on one printer and an optical beam break on the i3v with a solenoid that unlocks the probe all controlled by an attiny45

this is everything for the model in the video. solidworks parts + STL's + part drawings (for people that can't open solidworks files)
not tested not printed 100% not finished most likely never will be

I assume that it would need to put pressure on the plunger against a physical endstop to get a consistant stop point, to eliminate backlash or wobble

honestly a simple pull down spring with about 1/2lb pull with fix that
