Different Options

  • DRV8825
  • TMC 2100 - summary - the silent mode has very little torque, so not useful for 3d printers. In louder modes, it has more torque. Overall, better than DRV8825. Appears 2100 is discontinued.

  • TMC 2130 - supported in Configuration_adv.h. Since we typically want high speed and torque, silent mode may not be useful. But, video says that because of fine control over parameters, it works well whereas 2100 didn't work. For simplification in OSE's work - one top advantage is removing the need for endstops! That means reducing overall part count by 6 for endstop, holder, and wires - not to mention less wiring issues in the cable chain. This is worth pursuing.
