Arduino UNO and TMC2209 v1.2

Hi,
Appreciate your feedback regarding the following setup.

  • Arduino UNO v3
  • CNC shield V3
  • TMC2209 v1.2

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.

If You post links to the datasheet of the CNC shield, and the TMC helpers can tell for sure.
My guess is that the CNC shield handles up to 2.8 amps using heatsink and cooling fan.
