Extruders steppers do not work

Recently I purchased a diamond hotend. I followed the instructions from https://reprap.org/wiki/Repetier_Color_Mixing to install it. However, only the extruder 1 seems to work. I'm using a ramps with arduino mega. Can anyone help me?


  • Check all have steps per mm set and that the virtual extruders in eeprom have assigned a weight to the other motors as well. Only motors with a weight will move.
