My First CoreXY

[curious aardvark]

Ah - excellent explanation - so the stepper acts as it's own endstop sensor - clever - odd, but clever.
Presumably that means it can home in either direction.

Good logo - mind you how many americans actually know what a proper gear shift stick looks like ;-)
In case anyone doesn't know. In britain 90% of cars are manual shift and in the states 90% are automatic. I presume it's because your fuel costs about 1/3rd what ours does and automatics are nototiously bad on fuel economy.

I guess when we all go electric, that all changes.

And yeah, how do you do sensorless homing on a moving z axis ?
Particularly on a corexy - I presume you home it at the bottom of it's travel and it remembers where the start point is ?

Althogh it would probably make more sense to just have an moveable block at the top so that it's adjustable, should you change hotends or nozzles.
