Ignore async characters in gcode #20

Closed tbfleming closed 9 years ago

tbfleming commented 9 years ago

Autodesk decided that GRBL needs a % at the top of the file (they probably were testing with UGS or another horribly buggy sender). This causes grbl-panel to stop; it won't resume. Could you detect and ignore async commands?

Sorry to flood you with reports suddenly. Even with these issues this is a really nice tool. I got tired of dealing with UGS lockups.

no prob, should have these irritations slain by Tuesday. Yes, UGS lockups, prompted me to start this project as well :-) Gerrit

I misdiagnosed %. It's not an async command; it's standard gcode. From Wikipedia:

Demarcates the start and end of a program. Originally indicated the start and end of tape feed on NC machines, generally but not always required to be present on newer machines.

Still best to ignore it.

Fixed in V1.0.3.0
