How do I start setting up my machine?

Use the Machine Setup Files and Driver Setup Files as a guideline for setting up your machine.

First make yourself familiar with OpenPnP by reading through this document and watching this video by Opulo.

It is important that before starting to set up openpnp that your machine can move with just G-Code Commands. To make it simpler to understand: OpenPnP is a software that sends G-Code Commands to your Motion Controller and combines them with the Input of the Camera. Therefore it is important that your machine can already move, home and accurate the Lights, LEDs and Valves just by sending G-Code Commands. Only if this is given I would recommend moving to the OpenPnP Setup.

Machine Setup

At the Menu Tab Machine Setup I probably spent about 5 days understanding and modifying all the parameters in order to function as I wanted. That's why I want to make it easier for you to understand :)

Start by reading this chapter.

This is the best video inorder to understand how to set up OpenPnP!!! Thank you Stephen Hawes for all the work that you have put into this video!. This is also a great more detailed video!

Nozzle Offset Calibration

The nozzle offset calibration tool by OpenPnP is great. I would recommend using Blue Tack (patafix) stuck to the machine bed inorder to make a small mark with the nozzle and then move the camera to the mark to determine the nozzle offset. This is the easiest way I found to do this.
