G21 command unknown?

Post by b-morgan » Mon Dec 17, 2018 6:06 pm

I was looking at the serial.log (optionally) produced by OctoPrint and found this:

2018-12-17 07:29:29,636 - Send: N4 G21*30
2018-12-17 07:29:29,642 - Recv: echo:Unknown command: "G21"
2018-12-17 07:29:29,644 - Recv: ok N4 P15 B4

While the printer is idle, I can send a G21 and it indeed comes back as an unknown command. This seems strange to me.

TAZ 6, Marlin 1.1.9.28 provided with CuraLE 3.2.32.

Any suggestions as to what might be wrong? G21 seems like a fundamental command. BTW, M503 reports:
