Prusa will ask you to confirm whether the load was successful (e.g. The extruder will load your filament into a wastepile. If you have auto-load disabled - you will need to press a button to load. Pull out the filament immediately and press the button to continue.įeed new filament (color) in. If the extruder has already cooled, it is heated first. When you are ready: the screen tells you to push the button. If you do not babysit your printer, the wait will probably be too long, so extruder will coll down. Prusa will wait for you to change (unload) filament. How to properly change filament (for Prusa 3D printers) Replace '65' value in 'M140 S65' and 'M190 S65' commands with your desired value. Important Note: variable does not work (as of Simplif圓D 4.1), that is why I have used explicit temperature of 65. gcode file manually (remove tool change script from the first layer) or cope with (unnecessary) filament change at the start of the print. Alternatively, you may remove this condition and either clean up the generated. If you have to use the same color again later - you need to assign it to a new (virtual) extruder. This means that primary extruder (T0) is reserved to print base plate only. That is why I was forced to use tool head index. Unfortunately, Simplif圓D (as of 4.1 version) does not evaluate variables inside conditions in tool change script.

Go to 'Scripts' / 'Tool Change Script' and insert such code: Finally, since we do not have multiple extruders with different filaments ready to be used - we need to change filaments each time slicer wants to change extruder.
