what limit switch will i need to use and what probe do they sell it with the plug already on the wires ?

I believe it's pin a1 and yes the one I bought had the plug. Although the one I bought is an odd size. ( 14.2 mm ) I ended up grinding it down to 14. If I would have known how simple they are I would have just made one. All you need is an alligator clip to ground out on a slightly spring loaded piece of metal with wires connecting the two.

Is this board compatible with Lightburn software?

Yes, the LightBurn version for GCode controllers will run on this board. I got the WOODPECKER CNC CAMXTOOL V3.4 and I’m running the current trial version (LightBurn V0.9.16) now and have found no problems. Note: the trial contains both g-code and DSP versions.

How are the limit pins configured? Will the board recognize the pins or will the board just notify the software and its up to the software to stop?

The function of the limit pins is to notify the kernel on the board that they have been activated or deactivated depending on the type of limit switch you are using. IE a Normally Opened or Normally Closed switch. I do know the GRBL 1.1f kernel that comes with the board detects the change on the pins. However, you still need to set the software to do what you want it to do when detecting the change. IE like having the homing setting set in the GRBL settings $24 - $27 are the settings you want to set for homing.

do you need other board like arduino to make this work? Does it comes with software?

Yes it comes with software and you don’t need anything else
