I am new to programming Grbl. I need to set up my limit switches, I have 4 total switches, 2 for X and 2 for Y. I built a laser engraver by written instruction. I do not know what information I need to type to set them up. I am trying to learn how to program so please bare with me. My limit switches, when the trigger is touched blink, I have one for each axis (X & Y) one in + and one in - for each, total of 4. Thank You for anyones help. Bruce Wayne
My advice to everyone when using GRBL based controllers is to thoroughly read the GRBL wiki and refer to it often. It discusses all these things and will save a lot of time and confusion for people new to using GRBL based CNC machines. Here is a link to the limit switch portion.
