Arduino UNO v3 and TMC2209

Appreciate your feedback regarding the following setup.

  • Arduino UNO v3
  • CNC shield V3
  • TMC2209 v2

Considering to build a small CNC machine and GRBL would be used;

  • What is the max stepper motor (regarding the average current rates to run with no major heating issues) that could be used here among nema 17 and nema 23?
  • Any further recommendations regarding the above?

Note that I am still a beginner in that topic.

Thanks in advance.

Does the arduino uno/cnc shield with with TMC drivers? Does grbl? They would work in standalone mode, I guess.
