How to do home & bed leveling AFTER heating ?
August 12, 2017 12:47PM
My start GCODE contains
G28
G29


This works like:

While the head is docked (cannot ooze):
-the BED is heated, (takes 4-5 minutes)
-the extruder is heated, ~1.5 minutes.
-the printer does homing (oozing)
-and bed levelling. (oozing)

how can I configure a smarter script like:

1.- Turn on bed (do not wait - using the Slic3r preset, not just fixed tamperature)
2.- do homing
3 - do levelling
4 - go back to docking position (I have code for that)
5 - heat extruder (and wait - using the Slic3r preset, not just fixed tamperature)
6 .. print

this would save time, and prevent any undocked oozing.

M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
M140 S[first_layer_bed_temperature] ;set bed temp fast
G28 ;home all axis
G1 Z6 F1000 :raise Z B4 lvl bed
G29 ;lvl bed
G0 Z5 F1000
G1 X0 Y0 F3000
M190 S[first_layer_bed_temperature] ;wait for bed
M109 S[first_layer_temperature_0] ; Wait for all used extruders to reach temperature
G92 E0

Optional priming line in needed, insert after the G92 E0
G1 X5 Y5 Z0.25 F1000.0 ; go intro start pos
G1 X60.0 E11.0 F600.0 ; intro line

this line won't work correctly, as it uses waved brackets. ( looks like a line from Cura? )

well spotted, the command is correct but typed the wrong brackets.
