When the egg rotates, it can vary a little bit, so you don’t want to be too close, but you want to minimize the gap. Mount an egg and pen, and lower it slowly using M300 commands until the pen is close to but not touching the egg. “M300 S100” should pop the pen back up quickly. That will lift the pen to the top of its default travel.Įnter “M300 S115”, that should gently lower the pen a little bit. Recenter the arm with “G1 Y0”, then enter “M300 S100”. If only one axis is not moving as above, then you need to flip the wires for that axis. If they are moving as described above, UP is to the left, towards the motor. Otherwise, everything will come out backwards. If your motors are not moving in these directions, it is okay as long as they are BOTH moving in the “wrong” direction. Again, make sure it isn’t hitting anything. Type “G1 Y-480”, the pen arm should now swing all the way to the right. The pen arm should travel counter clockwise (to your left) to its limit. Type “G0 X0”, it should rotate back to the starting position. The egg motor should spin 180 degrees with the side facing you traveling down (counter clockwise looking at the face of the motor). Make sure you have “Newline” and "115200 baud” selected in the lower right drop downs. Click the serial monitor button in the upper right of the IDE.
