Filament dryer GCODE for your printer!

ON YOUR OWN RISK!

In general you need heat to dry filament. Only silica gel etc. is not enough to move the moisture out of your filament.

If you don't have a dryer like me, you can use your print bed for drying. You can use a small box for keeping the heat on your filament, but don't forget some holes next to the bottom and on the top to ensure a small air flow.

I made some GCODEs for the most common filaments with different print bed temperatures for drying filaments 6 hours straight. Prusa printers have a safety feature with switches off your print bed heating after 30 minutes preheat (and no print). Here the GCODEs are like “fake prints” to unlock the preheating for a longer amount of time, 6 hours this scenario.

Be aware that the GCODEs are really simple, so they are not officially supported by any printer. Because of that, they are summarized in a .zip file for uploading on printables. But they should work on the most of the printers which have a z axis (height) with minimum 200mm.

DO NOT USE THE GCODE marked as “DUMMY”. I had to upload some “official by slicer generated” GCODE to be able to save and publish “this model”. For drying use the simple GCODEs from the .zip file.

BE AWARE:

The GCODE homes the printer at first and moves the printhead to Z 200mm (in height). So wait and place your filament and box only after that is done.

THIS IS ON YOUR OWN RISK!

I recommend to store the filament in some dry box when drying / printing is done, but you can reuse the GCODE for drying so often as you want.

Have fun and post a mike from your setup!
