    Im using blackbox to control my laser, but have no z axis. I would like to start using homing for x and y, so I know I have to recompile Grbl to remove z homing. Is your version of Grbl for blackbox different than the regular Grbl? would it be ok to use that? or do you have a blackbox version without z homing available ?

    OpenBuilds Control -> Troubleshooting Tab > Grbl Flashing -> Flash Grbl 1.1g for ACRO (Acro is a 2 axis machine, so has Zhoming disabled as per gnea/grbl (already applied, compiled and available to you in CONTROL with no schelp)

    Apart from that easy way if you really want to compile, stock default works. Just set $4=1 (inverted driver enable)

    Is there a way to easily setup a custom homing sequence? In my build, we are using two motors in tandem- they are located on each side of a mobile platform, and driven by a blackbox. It would be great for those two motors to home synchronously, so as not to tilt the platform. Would love to be able to do this through OpenBuilds Control, but if I need to modify the GRBL config.h and recompile I can do that, I just dont know what to do with the recompiled GRBL - can I easily flash that to the blackbox?

    At this time, we do not support independant homing. A later version of the board might, but not at this time. To do that you need to wire Y2 as seperate driver entirely (not slaved as currently implemented on BlackBox)
