Questions tagged [prusa-i3]

The Prusa i3 is the third iteration of Josef Průša's RepRap 3D printer design. This is an open-source design, the tag should be used regardless of individual manufacturer. You might want to add the specific manufacturer or model as a separate tag.

The design of the i3 focuses on ease of construction and use rather than maximising the number of self replicated components. As summarized in the RepRap wiki, the following is a list of the main improvements made upon the Prusa Mendel Iteration 2:

  • Enhanced frame rigidity (prevents x-axis backlash)
  • Easy assembly
  • Parametric files for multiple sizes/bearings or bushings

How does the home position work on a Prusa i3 RepRap Printer?

By what process does the Prusa i3 determine it's home position? I have a feeling that it works like this, but I'm not entirely sure about it: If none of the end stops are activated; assume you are somewhere between Max-X, Max-Y, Max-Z and the…
