Running the jog at 100% seems like 50% when the computer is attached. Is this new in the updated software? Also the screen where the axis home all position is dark but the button is active ,is this feature disabled? Someone posted about loading files over wifi but I cant find that one.
Jog speed on PC is in mm/min. On Interface its a percentage of Max Rate: gnea/grbl Homing button is grayed out if Homing is disabled in grbl settings: gnea/grbl. Can also check your Grbl parameters on Interface from Tools and Util > Edit Grbl Profile Wifi: type IP shown on screen into a web browser on your PC. Make sure you are on firmware v1. 47 at the time of writing: docs:interface:firmware-update [OpenBuilds Documentation]
