What's the serial port setting?

GRBL 0.8 defaulted to 9600, but 0.9 uses 115200.

Did you clear the EEPROM?

Make note of the old settings and manually restore them?

The spindle enable pin D12 and z-limit pin D11 have switched places in v0.9i. Make sure you account for that.

You get that error from GRBL if your host software tries to use G1 moves to jog, but does not set the F parameter (speed). This used to work in GRBL 0.8, because there was a default value, but GRBL 0.9 follows the standard more closely, and forbids G1/G2/G3 without having set a speed. The state parameters confirm this.

Try using a different host program (G-code sender), or try upgrading to a version that supports GRBL 0.9 correctly.

Or, enter something like F200 (if in mm mode) and try jogging again.

Hi all, another newbie here. I'm trying to upgrade to the latest GRBL on my Shapeoko2 from .8 to .9j using Xloader. I'm upgrading so I can upload the Objectworks Laser software. I have Xloader v1.00 on my computer. I downloaded the hex file, set com3, baud 115,200 and the device UNO. When I hit upload, it says its uploading but I get the attached message. I've tried it with the board both powered and not powered. same message from Xloader. Can anyone tell me what I'm doing wrong.
Thanks in advance, Greg

Sorry, that attachment didn't download. Trying again. I get this error message from Xloader
when I hit upload button “unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. The system canot find the file specified.
