 However the generated GCODE was quite large, about 40kB, and the ESP32 threw an error when trying to receive it. It couldn't allocate enough ram. There's a few ways of solving this. I could potentially chunk up large programs into smaller pieces and send them through in a few separate messages, then stitch them together before playback.
-Another, much cooler solution, would be to listen to another MQTT topic that can be used to transmit Python generator code to the robot. This would be a cool way of sending quite complex pattern generators to the robot without using much RAM.

+=== Generators ===
+I wrote the structure to support sending short snippets of python code to the robot. These snippets must implement a generator function, named "generator", that produces a GCODE instruction on every request for them to produce a value. This lets me move my GCODE generator helpers that I was writing to generate GCODE straight into the microcontroller and run them there. Very handy.
+I also added code to save/list/delete generators already on the robot, so you can send your generators to be stored on the robot and then shuffle through them. Very nice.
