Can two Z probes be used with different controller pins?
March 10, 2021 12:23PM
The printer I am working on at the moment has two different Z sensors, one of which is a touch sensor used for bed leveling and the second of which is a single under-bed sensor used to find the heights (offsets) of each of the two nozzles.

The question is, is there any practical way to make the two calls using two different pins on the controller?

The actions of getting the two offsets at one point on the bed with the under-bed sensor, followed by getting a datum with a touch sensor at the same XY point, then following with a mesh bed probing can be seen (Repetier G codes) on a YouTube video at [] The reason for using two separate sensors is that I have found that dynamic effects can potentially make under bed sensors very inaccurate.
