Overview
BigRep has three moving Axis, X, Y and Z. If you are standing in front of the printer
the movement of the axis is as following:
› X-Axis: moves the extruder in X direction from le to right.
› Y-Axis: moves the X-Axis Y direction from front to back
› Z-Axis: moves the X-Axis and Y-Axis (portal) up and down
Mechanical Description
X-Axis and Y-Axis are driven by one stepper motor (Nanotec) each + belt and pul-
ley.
Z-Axis is driven by one stepper motor (Nanotech) + belt and several pulleys
Maintenance
Please have a look at section V - Maintence of the technical manual for further in-
formations.
All motors and pulleys can be replaced if needed.
X- and Y-Axis are using self-lubricated carriages and have to be lubricated with
industrial grease about once a year. We recommend mineral oil-based lubricants.
All belts have to be lubricated with silicon spray about once a year.
It is important to check the tension of the belts, which should be around 20Hz.
Note
As Silicon and Grease react with each other, please make sure that you never put
silicon spray at the X- or Y-Axis.
