m0913	Set Hybrid Threshold Speed	TMC driver switching to spreadCycle	mbuc	TMC2130|TMC2208|TMC2209, HYBRID_THRESHOLD	control	M913	At least one parameter must be used. Setting `X`, `Y`, `Z`, or `E` will set the hybrid threshold for all motors that fall under that category that have the `_IS_TRINAMIC` flag set. See examples below.	tag optional since description values I true 1.1.9 Index for multiple steppers. (i.e., `I1` for X2, Y2, Z2; `I2` for Z3; `I3` for Z4). unit type index int tag optional since description values T true 1.1.9 Index (tool) number for the E axis. If not specified, the E0 extruder. unit type index int tag type optional description X int true Set Hybrid Threshold for X to the given value. tag type optional description Y int true Set Hybrid Threshold for Y to the given value. tag type optional description Z int true Set Hybrid Threshold for Z to the given value. tag type optional description E int true Set Hybrid Threshold for E to the given value.	pre post code Set Hybrid Threshold for X and X2 to 100… …assuming that X and X2 are both Trinamic drivers. M913 X100 pre post code Hybrid Threshold for X and X2 are set to 100; Y is set to 120; E0 and E2 are set to 30… …assuming that X, X2, Y, E0, and E2 are all Trinamic drivers, but E1 is not.

When HYBRID_THRESHOLD is enabled, the TMC driver is switched from the quieter StealthChop to spreadCycle when the feed rate for a given stepper motor is over its _HYBRID_THRESHOLD.
