I just installed the dual extruder and have not been able to get the calibration squares to print correctly. I did the following.
- Installed Cura 19.12
- Set the extruder to the dual extruder v2 and flashed the firmware per the instructions
- Loaded the inner square first, then the outer square
- Left clicked on the inner square, then right clicked on the outer square and selected ‘dual extrusion merge’. I see a single square with the outside red and the inside green.
- Heated up both nozzles and the bed
- Clicked print
However instead of printing two enclosed squares - one in black and one in green, it printed two sets of enclosed squares apart from each other. Basically I see a square inside another square - twice - once in black and once in green. What am I doing wrong?
