##################### NOTES #########################
# 1) It seems as though a value is being sent immediately upon run:
#### C:\Users\david\Desktop\Embroidotron\June Updates\NeedleCallResponse2>python pythonSide.py
#### (4, 0)
# 2) Maybe moving to Gcode string format could be better for developing further commands
# 2.1) Possible Commands:
# 2.1.1) motors engage : turn on motors
# 2.1.2) activate stitch mode
# 2.1.3) activate travel mode, move to
# 3) I touched one of the cables/ plugged in a cord close to the signal wires and system stepped -- i.e. false run
