7.0 Calibration and Maintenance
7.2 Maintenance
In order to keep your Robox® in good working condition, as small amount
of maintenance is occasionally required. There are a number of routines in
AutoMaker™ that guide you through the process.
• AutoMaker™ is continually being improved - please check our website for an
updated version of the user manual if you require further information.
7.2.1 Purge Nozzles
When changing between two dissimilar materials, care must be taken to ensure
the heater block does not reach the degradation temperature of the starting
material. The purge routine sets the nozzle temperature to half way between the
melting point of the new and old materials and ‘purges’ the head by ejecting
mixed material onto the bed.
AutoMaker™ will automatically detect if the melt temperature in the loaded
material profile diers from the last filament that was used in the print head,
and prompt you to complete a purge routine. It is recommended to ALWAYS
complete this routine to ensure there are no remnants of degraded material in
the head which could cause a nozzle blockage. If you would like to force a purge,
it can be accessed from the toolbar on the Status screen.
