* tmc: Add support for periodic checking of driver statusKevin O'Connor2021-02-271-1/+76
| | | | | | | | Check the status of all Trinamic stepper motor drivers once a second. If the driver reports an error then invoke a shutdown. Also log any serious warnings. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Reinitialize on every driver enableKevin O'Connor2021-02-271-32/+36
| | | | | | | | | | | | | Send the full TMC stepper motor driver initialization sequence every time the driver is enabled. Don't raise an error on startup if unable to contact a tmc2208/tmc2209 driver. If the driver is still unavailable when it is enabled then a shutdown will be issued. This allows users to troubleshoot (and possibly bring up communication to the driver) prior to enabling the driver. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Always report values after a SET_TMC_CURRENT commandKevin O'Connor2021-02-271-14/+15
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Move SET_TMC_CURRENT command to TMCCommandHelper()Kevin O'Connor2021-02-271-1/+27
| | | | | | | Refactor the tmc driver implementations so that there is a single implementation of the SET_TMC_CURRENT command. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Improve error message on missing microsteps configKevin O'Connor2021-02-231-1/+2
| | | | | | | If microsteps is missing, warn about it in the stepper config section, not the tmc config section. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* endstop_phase: Obtain phases directly from stepper microsteps configKevin O'Connor2020-12-181-1/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Calculate step_distance from rotation_distanceKevin O'Connor2020-12-181-3/+9
| | | | | | | | Add support for automatically calculating the internal step_distance from new config parameters - rotation_distance, microsteps, full_steps_per_rotation, and gear_ratio. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Use configfile note_valid=False when inspecting stepper step_distanceKevin O'Connor2020-12-131-1/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc5160: diag0 support (#3159)Trevor Jones2020-08-091-4/+13
| | | | | Allow for diag0 only hardware to use sensorless homing. Signed-off-by: Trevor Jones <trevorjones141@gmail.com>
* tmc: Use new GCodeCommand wrappersKevin O'Connor2020-05-051-23/+21
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Revert incorrect changes to TPWMTHRS settingKevin O'Connor2020-02-201-26/+18
| | | | | | | | | | | | | | It's not valid to set the TPWMTHRS in a "klippy:connect" event handler because the TMCVirtualPinHelper and TMCCommandHelper classes were expecting that field to be set during the config reading phase. Revert "tmc: Fix typo preventing stealthchop threshold from being set" This reverts commit 7d76067ff9efaf75808b05f768dfef4295251ede. Revert "tmc: Query the stepper step_distance from the stepper object" This reverts commit 67b285224952749583d7bb3af3eb6397f63b492e. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* homing: Merge home_prepare()/home_finalize() into move_begin/move_end eventsKevin O'Connor2020-02-151-35/+34
| | | | | | | | Collapse the "homing:move_begin", "homing:move_end", home_prepare(), and home_finalize() into two new events: "homing:homing_move_begin" and "homing:homing_move_end". This simplifies the homing code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Fix typo preventing stealthchop threshold from being setKevin O'Connor2020-02-091-2/+3
| | | | | | Fix typo introduced in commit 67b28522. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Query the stepper step_distance from the stepper objectKevin O'Connor2020-02-011-17/+24
| | | | | | | Don't obtain the step_distance from the config, instead obtain step_distance from the instantiated stepper object. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Remove virtual_enable support and replace with automatic supportKevin O'Connor2019-11-121-33/+30
| | | | | | | Automatically detect if the stepper has a dedicated enable line. If it does not, then automatically enable virtual enable support. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc2209: Add support for sensorless homingKevin O'Connor2019-08-191-6/+24
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Integrate query_endstop_wait() into query_endstop()Kevin O'Connor2019-07-101-1/+0
| | | | | | There is no need to have two separate calls to query an endstop. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Configure "intpol" field from TMCMicrostepHelperKevin O'Connor2019-06-281-3/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Add support for virtual enable pinsKevin O'Connor2019-06-281-6/+34
| | | | | | | Add support for enabling the stepper via the communication channel. This improves support for boards with a shared enable line. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: It's not valid to schedule messages with print_time=0Kevin O'Connor2019-06-251-2/+2
| | | | | | | | A print_time of zero may translate to a negative clock on a secondary micro-controller, which would cause an internal error. Change the code to pass a real print_time or None if it is not needed. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tmc: Simplify internal DUMP_TMC interfaceKevin O'Connor2019-06-251-7/+9
| | | | | | | | Only the tmc2208 driver needs special read register translation logic. Rework the code so a default implementation is available for all the other drivers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* endstop_phase: Fix endstop_phase on trinamic drivers that aren't invertedKevin O'Connor2019-06-211-1/+1
