Good afternoon. Could someone tell me or explain to me what the correct values would be to assign to the stepper motor. to make a magnetic compass of C172. latest version of mobiflight 9.7.1

Multiply it times 10 to increase the integer resolution.

#

I the stepper config, use 3600 steps per revolution in the Sim scale and 2048 steps per revolution on the stepper

I don't know what values to put

Like I said, if using a 28byj-48, use 2048 steps per revolution.

#

For starting use max speed 1600, acceleration 800

And for this to work, the variable has to be multiplied times 10 in a Transform.
$*10

#

The origin for the stepper in a wet compass is always due north.

BTW this is my wet compass config.

The motor steps per revolution are set to 4096 because I configured the motor for half stepping which gives a smoother operation.

I do the x10 in the RPN code instead of a Transform.
