OctoKlipper

Notes here on getting everything setup for using Klipper in OctoPrint
Make sure your OctoKlipper plugin is installed and working.

Setting up basic macros

To make OctoTouchController (OctoTC) work for OctoKlipper you need to add some common macros to your printer.cfg file. These are:

1. PAUSE
2. RESUME
3. CANCEL_PRINT
4. M600
5. G29 (optional if you have auto bed leveling)

Code follows below:

[pause_resume]
#recover_velocity: 50.

[gcode_macro PAUSE]
rename_existing: BASE_PAUSE
gcode:
	# Parameters
	{% set z = params.Z|default(10)|int %}                                                   ; z hop amount

	{% if printer['pause_resume'].is_paused|int == 0 %}
		SET_GCODE_VARIABLE MACRO=RESUME VARIABLE=zhop VALUE={z}                              ; set z hop variable for reference in resume macro
		SET_GCODE_VARIABLE MACRO=RESUME VARIABLE=etemp VALUE={printer['extruder'].target}    ; set hotend temp variable for reference in resume macro

[gcode_macro M600]
gcode:
	PAUSE                ; call the PAUSE macro

[gcode_macro G29]
gcode:
	# optional: if you have auto bed leveling use this
	# or call your own custom macro from here
	BED_MESH_CLEAR
	G28
	M117 Heating the bed
	M140 S60
	M190 S60
	M117 Calibrating...
	BED_MESH_CALIBRATE
	SAVE_CONFIG
	G1 X0 Y0 Z5 F4000
	M117 All done

Once you have added these to your printer.cfg file you can change the Octoprint printer GCode scripts.
