I'm having problems upgrading to Marlin 2.1.1
I have a RAMPS 1.4 motherboard with A4988 stepper drivers. When I compile with
DEFAULT_AXIS_STEPS_PER_UNIT { 80.0, 80.0, 1259.84, 100.0 }
the X and Y axis move 50 mm when I give a G1 Y10 command, for example.
Setting the steps per unit manually with M92 X80.0 Y80.0 the axes perform normally.
I'm about out of ideas. I have not had this problem with previous versions.
Help, please.
