For the life of me I can't seem to figure out the Z-Min Endstop for a Inductive Sensor. I have LJ18A3-8-z/8X Inductive Sensor and it works. I have it wired right and the blue wire is in the Z-Min Pin on my Ramps board. It senses everything fine as the light lights up when near the the bed and all that, but in Marlin It does not change its trigger when I use M119. Nor does it stop the Z-Axis from moving. My settings are listed is below. Am I missing something? It there more settings than just this that needs to be changed? Both inverting it from True to False doesn't seem to help.

Guess I did burn something out on that Z-Min Pin. Oh well. At least I got it working now.]]> VectorRoll Firmware - Marlin Sun, 24 Sep 2017 01:47:11 -0400 https://reprap.org/forum/read.php?415,789455,789497#msg-789497 https://reprap.org/forum/read.php?415,789455,789497#msg-789497
Is there a way I can use the Z-Max endstop pin as for the Z-Min?]]> VectorRoll Firmware - Marlin Sun, 24 Sep 2017 01:34:15 -0400 https://reprap.org/forum/read.php?415,789455,789491#msg-789491 https://reprap.org/forum/read.php?415,789455,789491#msg-789491 Roxy Firmware - Marlin Sat, 23 Sep 2017 23:19:35 -0400 https://reprap.org/forum/read.php?415,789455,789481#msg-789481 https://reprap.org/forum/read.php?415,789455,789481#msg-789481

Well I did have the blue and black wires swapped. I switch them and now I can get the M119 Command to show the Z Endstop triggering when I put metal up to the sensor... BUT ... It still is not stopping the Z Axis from moving.

My X and Y Endstop's seem to work. They stop the Axis from moving. Its just this Z Endstop. It won't stop my Z Axis.

Setting up my Delta printer was so much easier than this.

If you have connected the brown wire to 12 volt, you may have damaged the endstop port on the mega.

Your probe is showing as a NPN NO type so the best way to connect it is as follows

NPN probe

Any diode should be ok, i use a 1N4148 type]]> obewan Firmware - Marlin Sat, 23 Sep 2017 15:41:00 -0400 https://reprap.org/forum/read.php?415,789455,789455#msg-789455 https://reprap.org/forum/read.php?415,789455,789455#msg-789455

Both inverting it from True to False doesn't seem to help.


Any help would be appreciated.
