Maintenance

Please do regular maintenance to allow the printer to serve you well and long. Maintenance includes:
 Cleaning the glass printing surface – do every time before printing to assure good adhesion of 3D
objects. Clean with glass or plastics cleaner and kitchen towel. If plastic has melted hard on the
surface, you may use a scraper or blade, but be very careful not to cut yourself or damage the
printing surface!
 External extruder cleaning – do every time before printing or as needed. Heat the extruder to at
least 200°C, and use kitchen towel folded in many layers to wipe off excess plastic from the extruder.
As always – be VERY careful and don't hold the kitchen towel on the extruder for too long and avoid
touching it with fingers. Use heat-protective gloves if needed;
 Cleaning and oiling of steel rods for each axis – do once in 2-3 months. Clean the rods carefully
with dry paper towel from dirt and grease. Oil the rods lightly in full length. You can use mineral oil,
special bearing oil or oil for bicycles;
 Calibration – as needed. Detailed description can be found in chapter 3.4.
