In order to load or unload the filament in your printer a simple G-code script can be used. Thees script can be copied to your SD-Card and be executed by simply selecting to print the specific program and it will be executed accordingly. Name your file so something that is easy to remember and maybe also put them in a subfolder on the SD-card for easy access. Name your file ex. “load.gcode” so the printer will recognize the file as a program There are two versions of each load/unload script, a simple version and a more advanced version. Please note that you will have to put in the lenght of the bowden tube on your printer in order to get the function working properly. The scripts can be downloaded as a zip-file on this link
