Finishing Touches

Reboot your pi

sudo reboot

Once it's back up It will take a minute to load, but we should see our DWC instance on our screen. You'll probably want to hit Ctrl + a few on a keyboard that's plugged into the pi times to get the mobile friendly view that works well with a smaller touch screen.

Start and Stop Sequences

There is no more start sequence to do the primer line before a print, or lower the bed when the print is done. You may want to use the following g-code macros bellow in your slicer. You may be able to incorporate them directly into klipper. I haven't gotten that far yet. It's adapted from Dr Lex's start and stop macros that I used with the native firmware.

Start g-code

M73 P0; enable show build progress
M140 S[first_layer_bed_temperature]; heat bed up to first layer temperature
M104 S140 T0; preheat nozzle to 140 degrees, this should not cause oozing
G21; set units to mm
G28 Z; home Z axis
G4 P0; Wait for command to finish
G90; set positioning to absolute
G1 Z5 F1500; move the bed down so we don’t crash any clips
G28;
G1 Z5 F1500; move the bed down again before we pre-heat so we don’t burn the bed
G1 X140 Y65 F1500; do a slow small move to allow acceleration to be gently initialised
G1 X-70 Y-83 F6400; move to waiting position (front left corner of print bed)

M190 S[first_layer_bed_temperature]; Wait for bed to heat up. Leave extruder at 140C, to avoid cooking the filament.
M109 S[first_layer_temperature] T0; set nozzle heater to first layer temperature
M116; wait for everything to reach target temperature
G1 Z0 F1000
G1 X-70 Y-74 F4000; chop off any ooze on the front of the bed
G1 Z[first_layer_height] F1500; move to first layer height
G1 X121 E24 F2000; extrude a line of filament across the front edge of the bed
; Note how we extrude a little beyond the bed, this produces a tiny loop that makes it easier to remove the extruded strip.
G1 Y-71 F2000
G1 X108 Y-74 F4000; cross the extruded line to close the loop
G1 X100 F4000; wipe across the line (X direction)
G1 X90 Y-79 F6000; Move back for an additional wipe (Y direction)

M73 P100; end build progress
M109 S0 T0; set bed temperature to 0
M104 S0 T0; set 1st extruder temperature to 0
M104 S0 T1; set 2nd extruder temperature to 0
G1 E-1 F300  ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 X0 Y0 Z150 F4000;
M18; disable all stepper motors

It might need some trimming, still poking at it.
