Unknown error: "exactly one of DEFHJPSR must be given"

[Duet_Science_Application]

I have encountered a couple errors that I do not know how to fix, the most pressing one being this "DEFHJPSR". Should I be worried?

Also, a linear-analog sensor I had set up in an io port had a lower than desired value output, but when trying the Uu/Vv parameters for the M308 command with values U0 and V1, the "too high" error in the picture come up. Any solutions or oversights?

@Duet_Science_Application which version of RRF are you running? Error messages usually include the command that provoked them.

The "exactly one of..." message comes from a M950 command.

I can't see any reason to use U and V parameters with a M308 command for a linear analog sensor because you can use the B and C parameters to set the scale. The V parameter is intended for small corrections to the slope of other types of sensor, so values below -0.2 or above +0.2 are forbidden.

@dc42 I see! That fixed all of my issues, thank you.
