limit endstop megapi with grbl
« on: December 27, 2019, 01:38:29 AM »
Hi,

How can I enable the limit switch with this Firmware: https://github.com/renebohne/grbl-laserbot.

It work great with many software, but I need to enable the limit switch for homing.
in Readme.md, i see it is in a6-a7, but when I make it on GND-SIG, it do nothing.

Can you help me?

Thank

I am not familiar with that firmware but homing is usually D9, D10 and D12 (X, Y and Z respectively) but you can assign any pins so typically I use single pin homing on a laser for ease of wiring. That is how my Grbl 1.1e DEFAULT firmware is configured in T2Laser.
