z-axis
The diagram below shows the machine coordinate system of the LongMill. It’s able to move in its x, y, and
z-directions due to the rails and respective gantries it has on each of those axes. We’ll start by assembling
the xand zgantries which combine into a singular assembly; in the diagram these are coloured red and blue
respectively.
Tools you need
Before you get started, here is a list of tools you should have on hand for assembly. Most people will have these
tools in their shop:
• Metric Allen keys or a drill and Allen driver bits
• Pliers or metric wrenches
• Asmallatheadscrewdriver
• Rubber mallet (optional)
