Use a frame-coupled temperature probe to compensate for thermal expansion in real-time. Signed-off by: Robert Pazdzior <robertp@norbital.com>
Add 'current_z_comp', 'frame_ref_temp', and 'state' to get_status. Match config_reference formatting. Signed-off by: Robert Pazdzior <robertp@norbital.com>
- move config checks to klippy:connect event - homing:home_rails_end for reference temp collection - Simplified homing axis check - Code cleanup: duplicate line, superfluous if statement - G-code help message updated to current naming Signed-off by: Robert Pazdzior <robertp@norbital.com>
Fixed docs reference outdated g-code commands: SET_FRAME_EXPANSION -> SET_FRAME_COMP QUERY_FRAME_EXPANSION -> SET_FRAME_COMP Signed-off by: Robert Pazdzior <robertp@norbital.com>
Implemented the same temperature smooth algorithm used by heaters. `smooth_time` config parameter is now available, with a default value of 2 seconds. Signed-of-by: Robert Pazdzior <robertp@norbital.com>
Adjust offset in increments of the Z step_distance, eliminating excessive adjustment and noise when position hovers around a step increment value. Status messages were also reworded for clarity (inactive rather than disabled when limits reached) Signed-of-by: Robert Pazdzior <robertp@norbital.com>
Take reference to a temp sensor config section rather than defining one internally. Primarily for display of frame temp in Klipper front-ends. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Calculate offset with a user-defined temperature coefficient rather than linear expansion calculation. Attempting to configure using the old params will throw a config error supplying the equivalent temp_coeff. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Update [frame_expansion_compensation] section to reflect config for the updated offset calculation method, using only temp_coeff. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Non-XY movements no longer remove the expansion offset, which created a Z 'bounce' on certain moves. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Add gcmd to manually set the frame expansion compensation homing reference temperature to the current value. Temporary (?) work-around for auto-Z calibration plugin, which homes without triggering the `homing:home_rails_end` event. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Warn about move to Moonraker plug-in for this feature. Signed-off-by: Robert Pazdzior <robertp@norbital.com>

Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Add optional `TEMPERATURE` parameter to `SET_FRAME_REF_TEMP` to override homing reference temperature. Overwritten on re-homing. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Add optional parameter `COEFF` to `SET_FRAME_COMP` to allow run-time tuning of the `temp_coeff` parameter. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Simplify config using `stepper_z` instead of a user-supplied stepper to determine the minimum Z adjustment increment. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Remove detailed state debugging method and reporting and rework `QUERY_FRAME_COMP` gcmd output. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Module renamed and variables, parameters, etc. updated to reflect this change as well as for clarity. Signed-off-by: Robert Pazdzior <robertp@norbital.com>

Use only degrees Celsius, drop reference to Kelvin. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Combine functionality of SET_Z_THERMAL_ADJUST, SET_Z_THERMAL_ADJUST_REF, and QUERY_Z_THERMAL_ADJUST into the SET_Z_THERMAL_ADJUST command. Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Signed-off-by: Robert Pazdzior <robertp@norbital.com>
Instantiate own temperature sensor object (a la temperature_fan) for thermal adjustment. Signed-off-by: Robert Pazdzior <robertp@norbital.com>

@Piezoid should also add a test for the config options, yeah? |

included in mainline as of today |
