If the filament curls to the left or right, there’s a big chance the hotend is partially clogged and you need to fix this before proceeding with the extruder calibration. The melted filament from the nozzle needs to be a continuous line of filament going down. and you should not encounter a lot of resistance when pushing it. The filament should be easily melted by the hotend. This is especially important to do if you previously printed other materials. This ensures that all variables are as close as possible to when you print.Īfter the hotend reaches the correct temperature, try to push some filament manually. It’s important to use a temperature close to what you normally use for printing. If using PETG, set a temperature of 225C. If you are performing the calibration using PLA filament, set a temperature of 195C. Computer with USB cable to connect the printerįor a successful extruder calibration, the hotend needs to be set at the correct temperature according to the filament used.In order to do the extruder calibration, you need to have the following:
