Hi guys, Dont know if it is normal, but when using the code G28, my machine goes the opposite side from my homing position. Is it normal? Otherwise, how could I set a different zero machine to be my homing position? I have a workbee with grbl(blackbox) and use openbuilds controller. Thanks for the help!
G28 : G Codes $H = homing G10 Lxxxx = set zero Use OpenBuilds CONTROL so you dont have to learn the commands just yet, we have easy to use Set Zero buttons See docs:blackbox:hello-world [OpenBuilds Documentation]
GRBL defaults the G28 position to 0,0,0, the same as machine home. If you move to anywhere and issue a G28.1 it will set the current position as the G28 offset. (make sure Z is high up else you will crash for sure) GRBL will remember this through powerouts, I use it for a manual toolchange position with a macro on a button.
also, if you give a $# command in the serial console it will display all your current offsets so you can see what it thinks G28 is set to.
Thank you so much for the quick reply! My machine zero was not at 0,0,0. Still dont know why it happened, but now everything works!
