# This file contains common pin mappings for the BIGTREETECH EBBCan
# Canbus board. To use this config, the firmware should be compiled for the
# STM32G0B1 with "8 MHz crystal" and "USB (on PA11/PA12)" or "CAN bus (on PB0/PB1)".
# The "EBB Can" micro-controller will be used to control the components on the nozzle.

# See docs/Config_Reference.md for a description of parameters.

## 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: 22.6789511   #Bondtech 5mm Drive Gears
## Update Gear Ratio depending on your Extruder Type
## - 50:17 for Afterburner/Clockwork
## - 50:10 for Stealthburner/Clockwork2
## - 80:20 for M4, M3.1
