Difficulty changing steps per mm of the extruder

StijnA

Hi,
for a project I had the task of changing the steps per mm in arduino code.

Where can i find this parameter?

I changed the value in the configuration.h map but this didn't do anything.

Kind regards,

If the eeprom is enabled on your controller board then the steps/mm stored in eeprom will take preference over the configuration.h.
You can update the eeprom with the values you changed the configuration.h by sending
M502 ;read default settings
M500 ;store to eeprom
