How many endstops are needed for a CoreXY printer?

zapta

This is for a Hypercube Evolution with a Duet wifi.
Is it reasonable to run it with one endstop for XMin, one endstop for YMin, and the inductive bed leveling sensor for ZMin?
That is, no endstops for XMax, YMax, ZMin and ZMax.
My goal is to simplify the design.
Thanks.

Yes, this is ok.

Hi,

You only need one endstop for each axis - they can be at min or max.

I level my bed manually so my Z axis endstop is just a micro-switch like the X and Y axes.

Yes.

I'm running a CoreXY printer with Xmax, Ymax and a Z-probe.
Using min-endstops works just the same.

Thanks everybody for the quick and very informative response. It will be MaxX, MaxY and BL sensor then.

(this is my first post here and I appreciate the help).

Oh, since it's a coreXY I should have mentioned this one as well.
