I found these OEM Codes:
OEM LED 113 Alternative feedrate in use (see OEM DRO 122) LED
OEM Button 299 Toggle bypass feed (enables value in OEM DRO 122)
OEM DRO 122 Feed rate ignoring that set in F word DRO
I added a button to my screen but it doesn't seem to work. The OEM LED works, and seems to indicate the alternate feedrate is active, but it doesn't change the feedrate.
Is anybody familiar with this feature?
