Hi, Using a Arduino CNC shield V3, connected three axis, Z, X, Y1Y2, all connected and running.
Three End Stops Nopen, microstep jumpers connected, jumpers on Y&A.
X and Y end stop are working. (X+ & Y+)
Z (+) End Stop does not work.
End Stop switches are tested for continuity and working, already interchange the end stop switch's still Z end stop does not work, change for Z- still not working.
Already change the Shield still same problem.
Using GRBL 1.1 and UGS 2.0.11 on windows 10.
Thanks in advance
