K40 Just stopped. Message at the bottom DMSG:’SH’l’SX’ to unlock

Another message DMSG Reset to Continue

Haven’t been able to locate any info on DMSG in the literature.

If I disconnect the K40’s power and unplug my C3D board I can get the K40 to give me jog control but when I execute RUN the K40 and the k40 locks up and I get one of the error messages. GRBL firmware.

suggestion: dont copy and paste all over the place. most of us are in all the groups I believe so repetitive posting is rather annoying.

It’s just “MSG: $H or $X to unlock”. Usually you get that if you hit a limit switch, so check to make sure those aren’t tripped.
