Prevent mess - how I'm doing it September 30, 2017 05:24PM |
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:
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!
