Trinamic stepper driver plugins
These plugins adds settings, M-Code extensions and reports for TMC2130, TMC2209 and TMC5160 stepper drivers.
They support Marlin-style M-codes such as M122, M911, M912, M913 and M914 - some with extensions and some with sligthly different syntax.
M-codes
M122 - output debug info or reset driver.
M122 axes <H-> <S-> <Q-> <I>
H- 0 = SFILT off, 1 = SFILT on (TMC2130) only.I- reinitialize driver.S- 0 = disable StallGuard and live output of sg-value, 1 = enable StallGuard and live output.Q- not yet enabled.
Examples:
M122 - output debug info for all enabled drivers. This is a plain text report, do not issue from a sender!
M122 Y - output debug info for Y axis only. This is a plain text report, do not issue from a sender!
M122 I - reset drivers.
M122 X S1 - enable live output of StallGuard value for tuning. Do not enable when running g-code jobs!
M906 - set stepper current
M906 axes
Note: Stepper current is not permanently stored.
Example:
M122 X700 Y950
M911 - Report prewarn flags
M911
M912 - Clear prewarn flags
M912
M913 - Set hybrid threshold
M913 axes
Note: Hybrid threshold is not permanently stored.
Example:
M913 X31
M914 - Set homing sensitivity.
M914 axes
Note: Homing sensitivity is not permanently stored.
Example:
M914 X31
Settings
Settings are provided for axis enable, homing, stepper current, microsteps and sensorless homing. More to follow.
$14x - Stepper current. x = 0 for X-axis, 1 for Y axis etc.
$15x - Motor microsteps. x = 0 for X-axis, 1 for Y axis etc.
Valid values are 1, 2, 4, , 8, 16, 32, 64, 128 and 256.
$338 - Driver enable
Parameter is a axismask where value is sum of X=0, Y=1, Z=2 etc.
NOTE: Some boards does not allow mixed drivers, for these this setting is not available.
$339 - Sensorless homing enable
Parameter is a axismask where value is sum of X=0, Y=1, Z=2 etc.
The driver and driver configuration has to be extended to support these plugins.
