Find best candidate library for executing GCode

[TyGuy]

We need a library for executing gcode in terms of motor outputs.

As far as my + Sandeep's current research, there are 3 main candidates:

• PyCNC:
  • https://pypi.org/project/pycnc/
  • https://github.com/Nikolay-Kha/PyCNC
  • Note: recommendation is to use pypy (JIT python interpreter) because that will allow the movement to be a bit faster and more accurate
• LaserGRBL:
  • https://lasergrbl.com/
  • https://github.com/arkypita/LaserGRBL
• PlottyBot:
  • https://ben.akrin.com/plottybot/
  • [See comment below for code link]

There may be others as well.

In my view, what's most important is:

• Smooth, correct operation
• Ease of integration, setup, & understanding
