NECESSARY ACCESSORIES Cleaning the machine, its interior and surroundings, especially the bottom plate under the platform Before each printing process To remove material remains from the interior of the device, use a vacuum cleaner or compressed air – a vacuum cleaner, – cleaning products with a high evaporation rate Cleaning the motherboard and the power supply unit from dust using compressed air Every 300 working hours Unscrew the bottom plate and use compressed air to remove dust – a 2.5 Allen key – compressed air

not clogged Before each printing process Cleaning the nozzle After finishing one spool of material Checking if the screws that secure the heater and thermocouple are tightened Every 300 working hours

NECESSARY ACCESSORIES Cleaning the perforated plate Before each printing process To remove material remains from the surface of the perforated plate, use a spatula – a spatula Checking the perforated plate for deformation Before each printing process – – Calibration Every 200 working hours If the platform calibration fails, move on to the next step indicated in this table – Cleaning the heatbed and the underside of the perforated plate Every 300 working hours Unscrew the screws that secure the perforated plate and remove the residues from the underside of the plate using a spatula. The heatbed needs to be cleaned with a piece of cloth damped in acetone – a spatula, – a piece of cloth, – acetone

ACTIVITY FREQUENC Y SOLUTIONS TO THE PROBLEMS NECESSARY ACCESSORIES Checking if the axes and the extruder guide rails are clean from material remains and dust Before each printing process It is possible to feel slight resistance while checking if the extruder moves freely on the guide rails. In such case you should check if the X/Y axes and the extruder guide rails are covered with black grime. The axes and guide rails should be cleaned with a cloth damped in acetone and then lubricated with silicone oil – silicone oil Checking the tension of the drive belts on the X/Y axes Every 300 working hours In order to check the tension of the drive belts on the X/Y axes, move the extruder to the central point and gently tug the belts. If the belts are loosened, tighten the screws placed on the top part of the X/Y axes blocks – Checking the tension of the drive belts between the motors and the X/Y axes Every 300 working hours – – Checking if the screws on the X/Y axes and the motor pulleys are tightened Every 300 working hours – – Checking if the extruder moves freely when the printer is off Every 300 working hours – – Lubricating the X/Y axes and the extruder guide rails Every 300 working hours – – silicone oil

material guide are properly installed Before each start-up of the printer Checking if the material guide is properly secured to the extruder cable with the material guide clamps Before each start-up of the printer If you use the HEPA Cover, check if it does not press the extruder cable Before each start-up of the printer Checking if the extruder cable is properly plugged into the extruder PCB Every 300 working hours Checking if the extruder PCB is properly secured to the extruder block Every 300 working hours Checking if the pins on the extruder cable connector are clean Every 300 working hours Checking if the screws that secure the hotend are not loose, and, if necessary, tightening them Every 300 working hours Removing the material remains and lumps from the extruder Every 300 working hours Checking if the fans are working Every 300 working hours Checking if the screws that secure fan shrouds on the extruder are tightened, and if it’s necessary, tighten them Every 300 working hours
