[FEATURE] Beacon Contact Support

[mjonuschat]

Implement support for Beacon Contact

This work is based on #637, incorporating the requested changes and implementing some bugfixes like reducing the probing temperature.

At the moment this PR expects the user to (manually) add the Beacon MCU to their overrides

[cdedwards]

This works well. I needed to remove some entries in my overrides.cfg but otherwise it seems to work very well.

[cdedwards]

maybe I spoke too soon. I had to remove alot from the beacon_contact.cfg file. home_xy_position can't be used.

Can you provide some more details? What did you have to remov? My overrides since creating the PR are pretty short and home_xy_position seems to work:

[beacon]
serial: /dev/serial/by-id/usb-Beacon_Beacon_RevH_BACE57925154364134202020FF141921-if00
home_xy_position: 150, 150
home_y_before_x: True
x_offset: -23.8

This is my beacon_contact.cfg in config/hardware/probes

[gcode_macro _USER_VARIABLES]

We can declare an "inductive_virtual" probe type as it's pretty close to the Beacon way of working and should just work!

variable_probe_type_enabled: "beacon_contact"
variable_startprint_actions: "bed_soak", "extruder_preheating", "chamber_soak", "clean", "beacon_calib", "tilt_calib", "bedmesh", "z_offset", "extruder_heating", "purge", "clean"

gcode:

Beacon probe definition also include the probe management macros directly from here

[include ../../../macros/base/probing/generic_probe.cfg]
[include ../../../macros/base/homing/homing_beacon_contact.cfg]

[stepper_z]
endstop_pin: probe:z_virtual_endstop
homing_retract_dist: 0

[beacon]
#home_z_hop: 5
#home_z_hop_speed: 30
#home_xy_move_speed: 350
#home_method: contact
#home_method_when_homed: proximity
#home_autocalibrate: unhomed
#home_gcode_pre_x: _HOME_PRE_AXIS AXIS=X
#home_gcode_post_x: _HOME_POST_AXIS AXIS=X
#home_gcode_pre_y: _HOME_PRE_AXIS AXIS=Y

#home_gcode_post_xy: _HOME_XY STAGE=post
contact_activate_gcode: ACTIVATE_PROBE
contact_deactivate_gcode: DEACTIVATE_PROBE
contact_max_hotend_temperature: 180

without removing all the home_'s as well as the adding max_hotend_temperature, my printer will not start.

That seems very weird, not sure why none of the beacon config settings would work for you. What is the exact error message when they are enabled, can you upload a fresh klipper.log that includes the error?

[cdedwards]

[klippy.log](https://github.com/user-attachments/files/23291241/klippy.log)

[mjonuschat]

Just to confirm, you're on Beacon Firmware 2.0 or newer - because those config options all got added in that firmware version.

[mjonuschat]

And it looks like the log didn't upload properly

[cdedwards]

klippy.log

[cdedwards]

and yes I'm updated to latest on beacon firmware.

[smweil]

Having the exact same issue. Firmware up to date on the beacon and klipper on the latest...

Do you mind uploading a Klipper.log that show the error? The last log was inconclusive.
Also just to make sure, you're on the develop branch?

[smweil]

I fixed the issue, you must include in [beacon]
home_xy_position: 150, 150

for the module to load properly.

[mjonuschat]

Sweet, I'll see how to incorporate it into the PR or set a safe default value

[mjonuschat]

Beacon config will be checked on startup to make sure home_xy_position has been defined:
