7.0 Calibration and Maintenance
7.1 Calibration
Occasionally Robox® will need to be calibrated to ensure the quality of printed
output. This is particularly important on first use or if the unit has been moved or
subjected to large shocks or vibration.
The majority of the setup of the machine is performed automatically during
the print process, however there are some parameters which vary between
machines/heads. These calibrated parameters are stored in the printhead and
should only need to be performed once or twice during their lifetime.
All calibration procedures are performed with AutoMaker™, and therefore your
Robox® must be connected to your computer with the USB cable. They can be
accessed through the Advanced Settings Tray on the Status screen.

AutoMaker™ is continually being improved - please check our website for an
updated version of the user manual if you require further information.
7.1.1 Nozzle Opening
This routine is used to calibrate the point at which the needle valves in the head
operate. The firmware has to know the point at which the plastic begins to flow in
order to accurately control extrusion.
There are a number of things you need to check before starting the calibration
sequence:
•
You have a Robox® SmartReel™ installed in the material dock
•
Extrusion is working correctly, and material can be extruded from both
nozzles - if this is not working, please try completing the Purge sequence
under Maintenance - see section 7.2.1
•
The bed is clear of all obstructions
•
The nozzles are clean with no lumps of filament or degraded material
•
A pair of tweezers (included in the accessories box) would be useful for
removing extruded material during the calibration.
