| + | * If you carry the printer around, execute „Calibrate Z“. The bed calibration is done every time before printing, so it isn’t necessary to do this manually. | ||
| + | * You can print (amongst others) PLA and PETG well with this printer. Using PETG might be interesting to print transparent or more flexible objects, but it suffers a bit from stringing while printing. | ||

| + | * When your heatbed adhesion is too low with PLA, try to clean the heatbed with Isoprop Alcohol. | ||
| + | * When you print PETG it’s advised to NOT clean the heatbed with Alcohol, as this might increase adhesion too much. PETG does stick very well to the heatbed. Important: It is recommended to use some window cleaner to clean the surface which is good enough for cleaning the heatbed while keeping the adhesion low enough. This was noted in the manual for the Prusa. | ||
| + | * To get a more transparent print when using transparent PETG, you can try to increase the extrusion rate by 5-10%. This will fuse the material a bit more tightly together, reducing the amount of little gaps that might hinder the light to shine through your print easily. | ||
