Does A1 use Motor Current Detection On X Axis limit detection

When A1 is homing part of the process is going to the very left of the x axis. I wonder how it knows the limit. It doesn’t use switch, a hall effect sensor, and less likely an encoder.

An Idea cameout to my mind maybe the plastic cover or the purge wiper is the reason. I think A1 utilizes some kind of current spike detection. Well motors draws more current under stress. Maybe I’m wrong I’m gonna test it soon by blocking the toolhead intentionally

Yes.
