Question Upgrade to SB - motor config

When upgrading a toolhead from AB to the SB do I need to change anything in the config file for the smaller pancake stepper motor on the extruder? Using octopus v1.1 on a Voron 2.4r2.

Thanks in advance.
 
Most of what you need to know can be found in your printer.cfg. You might have to change the rotation by adding or removing the "!" shown in RED below. You will need to perform an extruder calibration and the "gear_ratio" as shown below, also in RED.

# Extruder
#####################################################################

## Connected to MOTOR_6
## Heater - HE0
## Thermistor - T0
[extruder]
step_pin: PE2
dir_pin: PE3
enable_pin: !PD4
## Update value below when you perform extruder calibration
## If you ask for 100mm of filament, but in reality it is 98mm:
## rotation_distance = <previous_rotation_distance> * <actual_extrude_distance> / 100
## 22.6789511 is a good starting point
rotation_distance: 21.5 #Bondtech 5mm Drive Gears
## Update Gear Ratio depending on your Extruder Type
## Use 50:10 for Stealthburner/Clockwork 2
## Use 50:17 for Afterburner/Clockwork (BMG Gear Ratio)
## Use 80:20 for M4, M3.1
gear_ratio: 50:10 #BMG Gear Ratio
microsteps: 32
full_steps_per_rotation: 200 #200 for 1.8 degree, 400 for 0.9 degree
nozzle_diameter: 0.4
filament_diameter: 1.75
