I know you can switch axis directions by using the $ in grbl not sure if i incidentally click something in light burn to revers the x and y but in lasergrbl when i use the jog arrows everything works like it should, so i know i seen a setting to reverse x and y in light burn but i can find it.
Where do you have your machine origin set? Could this have changed?
I will check but it was working fine last night that why im thinking i might of clicked on something im using a laptop and using the touch pad so i may have accidentally clicked on something without noticing
I check the origin not sure what going on but lasergrbl everything is jogging right with the arrow keys just reversed in light burn.
