There is an issue with your code that caused the destruction of my latest print.

You have two commands in one line:

There is a line break missing.

In combination with the next code line, this crushed my print head into my contruction.

Of course it was not intentionally, but this is a warning to the other printer friends.

Hi guys,

I was annoyed by the oozing of the PETG at the beginning of the prints , so it modified a little the start G-code in Prusaslicer:

G90 ; use absolute coordinates

M83 ; extruder relative mode

G28 ; move X/Y/Z to min endstops

G1 Z10 F2000 ; lift nozzle for cleaning

G1 X0 F500 ; align to the left side

G1 Y3 F1800 ; move bed out of the way

M140 S ; set bed temp

M190 S ; wait for bed temp

M104 S ; set extruder temp

M109 S ; wait for extruder temp

G1 Z0.28 F2000 ; nozzle above bed

G1 E-2 F2000 ; Retract filament

G1 X5 F500 ; align to the left side

G92 E0 ; zero the extruded length

G1 X150 E30 F500 ; Extrude 30mm of filament in a 15cm line.

G92 E0 ; zero the extruded length again

G1 E-0.2 F500 ; Retract a little

G1 X190 F4000 ; Quickly wipe away from the filament line.

M117

And i had some lines to the end G-code:

M104 S0 ; Extruder off

M140 S0 ; Heatbed off

M107 ; Fan offG91 ; relative positioning

G1 E-5 F3000 ; retract filament

G1 Z+0.3 F3000 ; lift print head

G28 X0 F3000 ; move home

G1 Y200 F3000 ;Present print

M84 ; disable stepper motors

Quite happy with the results :)

Cheers
