Determine bed leveling sensor
Open, Needs TriagePublic

Description

We need to determine what switch or other sensor we want to use for bed leveling. One option is the one E3D is using with the toolchanger, but we are awaiting information on operating temperature and repeatability.

Another switch that has been proposed is https://www.metrol.co.jp/en/products/positioning-switch_pt/

E3D toolchanger switch is rated for 85C which should be acceptable

Measured repeatability over a 10 cycle test on a single sample switch showed a range of 0.023mm
