title: L6474 Thermal Warning Test
|
|
brief: Find L6474 drive level (KVAL_HOLD) threshold
|
|
author: shitcreek
|
|
|
|
requires: MONITOR_L6470_DRIVER_STATUS
|
|
group: L6474
|
|
|
|
codes: [ M916 ]
|
|
related: [ M917, M918 ]
|
|
|
|
notes:
|
|
- Requires `MONITOR_L6470_DRIVER_STATUS`.
|
|
- All tests assume each axis uses matching driver chips.
|
|
- On the L6474 the TVAL is used instead of KVAL.

`M916`: increase KVAL_HOLD until thermal warning.
|
|
This routine is also useful for determining the approximate KVAL_HOLD where the stepper stops losing steps. The sound will get noticeably quieter as it stops losing steps.
