Hopefully correct format
DIY Router
Arduino UNO R3
Engraver shield
Easel 0.3.10
Grbl 1.1F
Fitted and connected the end switches. Attempted to home the the machine. The Z axis activated first but the micro switch did not stop travel.
Went into the Machine Inspector to check end stop operation . X and Y work OK but not Z. Moved the wiring about on the board to prove the switches, with all switches working except when connected to Z +ve or -ve .
Is it something I have missed?
Any advice much appreciated.
I am assuming that the "engraver shield" is a protoneer grbl shield.
In grbl 1.1, variable spindle speed (PWM) is enabled by default. With variable spindle speed enabled the Z axis limit switch connects to spindle enable (SPNEN pin12) and the PWM to the spindle motor controller comes from Z+ or Z- limit switch connector (pin 11). See the config.h file in the grbl folder for more information.
I thank you for your replies.
The wiring digram is a N/O micro switch connected across the End Stop connections on the shield.
Code. Total novice so am a bit lost with what you require.
"protoneer grbl shield". I assume so
I am guessing that there is something in the settings that will allow me to take Z out of the homing cycle but again not sure where to look although I can see setting in the Machine Inspector

Enable homing cycle by setting $22=1.
If you want to customize which axis are homed and the order of homing the axes, you need to edit the config.h file, re-compile and upload grbl.
I thank you very much for your reply. At moment reading through file.
From my brief look my end stops can be used for homing or a limit. I have run a test carve however when I activate a limit switch nothing happens. Activating emergency stop does work.
Should I have both $20=1 & $22=1?
Well decided not to be lazy and experiment. Turned $21 on and micro switched now work. Other problems now so will persevere . Thanks again
