hi scholtz, i went through the comments so that i can get an idea to adapt the scad file for my mk7 12x12mm sized so these are the settings that i used
// drive gear
drive_gear_outer_radius = 12.00 / 2;
drive_gear_hobbed_radius = 11.00 / 2;
drive_gear_hobbed_offset = 3;
drive_gear_length = 11;
drive_gear_tooth_depth = 0.2;
but i am facing a problem that i have to fully tighten the idler to make it work and still the extruder skips a lot so if i could just tighten it 1mm more than that would have been more than enough. Can you please guide me what do i need to change to get the desired results
