To keep the machine operating properly, and to extend its service life, we recommend the following maintenance schedule.
The frequency at which you will need to perform preventive maintenance tasks will vary depending on how much you run the machine, the temperature you run it at, and if you use one or two toolheads. Your machine will require maintenance more often when operating consistently at high temperature. It will also require maintenance more often with a high number of printing hours.
The following schedule is based on an average printing time of 30 hours a week at a chamber temperature of 120°C or less.
