* stepcompress: Add support for tracking history of queue_step commandsKevin O'Connor2021-03-131-1/+10
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Improve error messages on missing rotation_distanceKevin O'Connor2021-02-231-5/+8
| | | | | | | | If neither rotation_distance nor step_distance is present, then generate an error saying rotation_distance is needed (instead of an error about step_distance). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Don't cache ffi_lib object in the stepperKevin O'Connor2021-02-181-20/+25
| | | | | | | It's easier to just call chelper.get_ffi() if the ffi_lib object is needed. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* buildcommands: Extend number of available mcu messages from 96 to 128Kevin O'Connor2021-02-181-9/+9
| | | | | | | | | | | Some internal code treats the message ids as encoded "variable length quantities", while other internal code assumes the message id is always one byte long. Continue using this scheme, but convert the VLQ users to use the name "msgtag" while the 1-byte users use "msgid". Increase the number of available msgids from 96 to 127 - the higher values get encoded as negative "msgtags". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Calculate step_distance from rotation_distanceKevin O'Connor2020-12-181-1/+42
| | | | | | | | 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>
* homing: Prefer printer.command_error() instead of homing.CommandError()Kevin O'Connor2020-09-041-1/+1
| | | | | | | Update callers to use the printer.command_error reference instead of directly using homing.CommandError() when raising or catching errors. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Add support for commands to send only on a host restartKevin O'Connor2020-07-251-2/+2
| | | | | | | | Add a new "on_restart" parameter to mcu.add_config_cmd() and only send those commands on a host restart that does not involve a micro-controller restart. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Make sure to reload trapq in set_stepper_kinematics()Kevin O'Connor2020-06-301-2/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* klippy: Rename try_load_module() to load_object()Kevin O'Connor2020-05-081-3/+3
| | | | | | | | Rename try_load_module() so that it uses consistent naming for "printer objects". Change the function to raise an error by default if the specified module does not exist. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: No need to pass stepper_kinematics to set_step_dist()Kevin O'Connor2020-03-281-3/+2
| | | | | | | Also, no need to log in stepper.py as the update is already logged in extruder.py. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Extruder: Add g-code to set extruder step_distance (#2598)David Smith2020-03-281-0/+4
| | | Signed off by: David Smith <davidosmith@gmail.com>
* stepper: Add a config check for obvious incorrect homing_positive_dirKevin O'Connor2020-03-241-0/+7
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Introduce new lookup_query_command() command wrapperKevin O'Connor2020-02-201-4/+4
| | | | | | | Use new mcu.lookup_query_command() for all commands that query information from the micro-controller. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* homing: Ability to set retract speed between homing moves (#2487)FanDjango2020-02-121-4/+6
| | | | | On the retract move between homing moves, use a different speed (typically a faster one). Signed-off-by: Mike Stiemke <fandjango@gmx.de>
* itersolve: Add ability to query the active_flags stateKevin O'Connor2020-01-231-0/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Export itersolve_calc_position_from_coord()Kevin O'Connor2020-01-061-3/+8
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Track if using units of radians instead of millimetersKevin O'Connor2020-01-061-5/+12
| | | | | | | | The STEPPER_BUZZ command needs to know if the axis is using radians instead of millimeters so that it can move a more appropriate distance. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Remove set_commanded_position() callKevin O'Connor2019-11-131-12/+6
| | | | | | | | Now that the only caller to set_commanded_position() is set_position(), remove the set_commanded_position() method and pass the set_position() call directly to the itersolve.c code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Do not call itersolve_set_commanded_pos() after homingKevin O'Connor2019-11-131-2/+1
| | | | | | | | Now that the homing code does not use get_commanded_position(), it is no longer necessary to alter the low-level commanded position after a homing move. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Add get/set_tag_position() and convert calc_position()Kevin O'Connor2019-11-131-1/+7
| | | | | | | | | Rename calc_position() to calc_tag_position() and have it calculate the value of the position from the last stepper set_tag_position() call. This enables the calc_tag_position() code to be more flexible as it can be run with arbitrary positions. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Remove add_to_endstop() methodKevin O'Connor2019-11-121-7/+2
| | | | | | | Now that the PrinterStepper and MCU_stepper classes have been merged, there is no need for the add_to_endstop() method. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Merge PrinterStepper and MCU_stepper classesKevin O'Connor2019-11-121-69/+48
| | | | | | | There's no need to track the two classes separately - just combine them. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Move MCU_stepper from mcu.py to stepper.pyKevin O'Connor2019-11-121-2/+139
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Simplify PrinterRail initKevin O'Connor2019-11-121-23/+18
| | | | | | Use add_extra_stepper() during class init. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper_enable: Move enable tracking from stepper.py to stepper_enable.pyKevin O'Connor2019-11-121-68/+7
| | | | | | | Move the enable line tracking out of the main stepper.py code. This simplifies the main kinematic code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper_enable: Move motor_off() logic to stepper_enable.pyKevin O'Connor2019-11-121-0/+1
| | | | | | | | Directly disable all the stepper motors on a global motor_off() from the StepperEnable() class in stepper_enable.py. This simplifies the toolhead and kinematic classes. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper_enable: Add new extras module for stepper enable line trackingKevin O'Connor2019-11-101-0/+2
| | | | | | | Move the M18/M84 command handling from gcode.py to new stepper_enable module. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Remove unused gen_steps()Kevin O'Connor2019-11-061-6/+0
| | | | | | | Eliminate the old gen_steps() call now that all callers have been converted to the newer trapq based generate_steps(). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Remove set_ignore_move()Kevin O'Connor2019-11-061-1/+0
| | | | | | | Update callers of set_ignore_move() to use the trapq system to set a stepper to ignore moves. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Add support for generating steps from a trapqKevin O'Connor2019-11-061-0/+14
| | | | | | | Support associating a stepper_kinematics with a trapq. Support generating steps from a time range on the given trapq. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Add support for providing a list of pins to enableKevin O'Connor2019-06-281-11/+23
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* endstop_phase: Fix endstop_phase on trinamic drivers that aren't invertedKevin O'Connor2019-06-211-0/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* endstop_phase: Move endstop phase homing code to new "extras" moduleKevin O'Connor2018-10-161-57/+0
| | | | | | | Move the endstop phase tracking code from stepper.py to a new extras/endstop_phase.py module. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Add a set_commanded_position() method to MCU_stepperKevin O'Connor2018-10-101-3/+7
| | | | | | Add the ability to directly set the "commanded" stepper position. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Wrap lines to 80 columnsKevin O'Connor2018-10-091-3/+6
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Adding support for a second_homing_speed parameter (#677)Chris Whiteford2018-10-041-2/+3
| | | Signed-off-by: Chris Whiteford <chris@chrisandtennille.com>
* probe: Infer position_endstop when using probe:z_virtual_offsetKevin O'Connor2018-10-011-1/+3
| | | | | | | | | Don't require (or permit) the user to specify a stepper_z position_endstop when using the probe:z_virtual_offset mechanism. In that case the position_endstop should always equal the probe's z_offset - so no need to have the user specify it. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* force_move: Rename stepper_buzz.py to force_move.pyKevin O'Connor2018-07-261-2/+2
| | | | | | This is in preparation for extending the ability to make manual moves. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Minor whitespace changesKevin O'Connor2018-07-261-17/+19
| | | | | | Wrap lines at 80 columns. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* pins: Explicitly pass can_invert and can_pullup to lookup_pin()Kevin O'Connor2018-07-261-3/+5
| | | | | | | | | | | | Don't pass pin_type to lookup_pin() - instead, if a pin can be inverted or can have a pullup, then the caller must explicitly specify that when calling lookup_pin(). This simplifies the code for the cases where it is not valid to invert or pullup. Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin() apply default pullup and invert flags. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Support calculating a stepper position from a cartesian coordinateKevin O'Connor2018-07-181-0/+1

* query_endstops: Move QUERY_ENDSTOP command to it own extras/ moduleKevin O'Connor2018-07-161-3/+10
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* mcu: Enhance itersolve stepper kinematics allocationKevin O'Connor2018-07-131-6/+4
| | | | | | | Allocate the stepper_kinematics directly in mcu.py - that way the kinematic classes don't have to interact with the chelper code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Support setting the stepper position via a cartesian coordinateKevin O'Connor2018-06-221-2/+2
| | | | | | | | | Add support for an itersolve_set_position() function that sets a stepper position from a cartesian coordinate. This eliminates the need for both the python and C code to be able to translate from a cartesian coordinate to a stepper position. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Replace PrinterHomingStepper with PrinterRailKevin O'Connor2018-06-221-75/+83
| | | | | | | | Update the code to use the term "rail" when dealing with a motor controlled "axis". A rail has a series of steppers and endstops that control that motor controlled "axis". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Add a get_homing_info() method to PrinterHomingStepperKevin O'Connor2018-06-221-1/+7

* stepper: Don't peak into PrinterStepper membersKevin O'Connor2018-06-221-4/+8
| | | | | | | Add additional wrapper functions so that no outside callers need to peak into the member variables of PrinterStepper. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Add a is_stepper_enabled() method to PrinterStepperKevin O'Connor2018-06-221-0/+2
