    Is it possible to have coordinated moves with the speed of extrusion? For example, if my movements are fast, the extrusion should be setup to dispense at a faster rate and when my movements slow down, the extrusion should be setup to dispense at a slower rate.

    Thank you!

    You are likely thinks about a 3D printer type application. TinyG will do whatever the G code tells it to do, but all motion will be subject to the jerk motion enhancement that seeks to maximize machine efficiency (time spent on the job). Some folks have used the A axis to coordinate some variation in extrusion rate.

    You may want to research the G2 project somewhat, it is aimed at providing the motion foundation for 3D as well as 2D motion.

    tinyG is rather resource limited (memory, CPU).
