I am using GRBL controller ver 1.6 to control either an arduino UNO or a NANO loaded with GRBL ver 0.9. When I jog Z axis, it works ok. When I attempt to jog Y or X axis, I get message 'undefined feed rate'. The 'code' window shows that I have issued a g90(or 91) command, with no feed rate in the command. This has worked ok using same and different hardware ( but same software versions) in the past few days. Other than jogging, the system works ok. Is the jog rate for Y and X stored in a configuration file anywhere? Regards Alvey
