[BUG] M220 in gcode does not change feedrate

[evilDave]

Did you test with a precompiled firmware?

Yes, and the problem still exists.

Bug Description

I am printing the speed calibration from teaching tech: https://teachingtechyt.github.io/calibration.html#speed That calibration uses M220 to increase the feedrate during the test. I see the gcode commands in the gcode file, the speed should be going from 80 to 100, 120, 140, 160 but there are no speed increases during the print.

I can adjust the speed using the LCD panel, which I thought did much the same thing as M220...
