Shapeoko 3: GCODE Errors

CNC Machines Shapeoko
1

Using Shapeoko 3 with GRBL 1.1f.

Got the following errors from the console with this gcode, but I have no idea why. Been using 1.1f for months with no issues.

Could it be the sender? Using cncjs V1.9.7.

Please check and see if it’s the sending program by using a different program — Grbl does have a testing mode:

$C

Really don’t understand why all G-Code senders don’t at least have an option to use this mode the first time a file is sent — you could even automate it by doing a hash of the file, comparing it to a saved list of all previously sent files, and if not found, sending it in $C check mode, then if it’s successful, store that hash.

It looks like the issue is with the sender. CM4 and CNCJS 1.8.17 don’t have the errors. I will discuss with the developer.

A testing mode would be a great feature.

Thanks
