Hi Community, I wanted to share something that really helped me. I hope it is helpful to any of your setups.
Before: Bed & Extruder heated up, I was sitting there with a pair of pliers waiting for the initial plastic to come out of the nozzle due to heating up and I was trying to catch it before printing actually starts. If I didn't do that, there would have been a mess, almost no print would go through.
After: With this improvement, I do not have to intervene anymore, a little blob of plastic will be extruded even before printing the skirt.
Here's how I did it in the Slic3r Start Gcode:
G28
G1 Z5 F5000
M107
; Start blobbing
G21
M104 S[temperature]
G90; set absolute coordinates
G1 X10 Y10 F3000
M109 S[temperature]
G1 Z[first_layer_height] F200
G92 E0
G1 E7 F200
G1 X12 Y12 F200
G92 E0
G1 E7 F200
G1 X14 Y14 F200
G92 E0
G1 E7 F200
G1 X16 Y16 F200
G1 X50 E15 F200
Before you copy&paste this code, please look at each of the commands and judge if you need it or not and in particular verify that it doesn't break your hardware.
Here's what it looks like:
The little brown spot next to the line is a piece of burnt filament that came off using this method, it was filament that curled and went back to the heating block. The stuff doesn't come off 100%, but it won't disturb the print.
Enjoy!
