With reference to the above link, can we add the Ooz free Gcode in mini Kossel follow by G29 like this:


M302 ; Allow cold extrusion to avoid USB errors
M220 S100 ; Set feedmultiply back to normal (100%)
G28 ; Home to top 3 endstops
G29 ; Autolevel

G92 E0 ; reset extruder
G1 Z0.3 ; move z to 0.3mm to avoid scraping bed
G1 X85 Y0 F4000 ; move half way along the front edge
G1 Z0.05 ; move nozzle close to bed
M109 S185 ; heat nozzle to 185 degC and wait until reached
G4 P120000 ; wait another 120 seconds for nozzle length to stabilise
G1 E5 ; extrude 5 mm of filament
G1 X35 F12000 ; move 50 mm towards the origin as fast as firmware permits
G1 Z1 ; lift nozzle to 1 mm ready to begin main sequence
G92 E0 ; reset extruder

M107 ; Turn fan off for the first layer.

Any better suggestion?

Oozing always mess up the first layer and I have to follow the nozzle and remove, secondly even I add 3 loop of skirt to purge the nozzle but the perimeter still missing in some smaller prints.
