Difficulty changing steps per mm of the extruder

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
  • Thanks man, you saved my ass (and the printer from being thrown against a wall from frustration)
