Hall effect sensor & Xcontroller

[ErikJenkins]

I switched out my switches with hall effect limit switches:

Limit switches or not?

Just to add a little more to this thread…I switched out my mechanical switches for magnetic hall effect sensors. 2 on the X and Y axis and 1 at the top of the Z-Axis. I am NOT using shielded wire, I simply twisted three wires together and ran them from the sensor to the controller…no false triggers yet. Homing and limit switches are turned on in GRBL. The switches will stop the gantry moving 200 inches per minute without a collision (I tried this a few times…on purpose ). I …

Yesterday I removed my mechanical homing/limit switches as I started getting noise like several others. I replaced the homing switches with hall effect limit switches. I purchased 5 of them from: These switches have 3 connections instead of the 2 on the mechanical ones. 1 goes to the Arduino Ground, 1 to the Arduino +5 volts and the third to the appropriate pin just like the mechanical switches. There are 2 LEDs to indicate the state, tripped or not, red and green. I have run the homing …
