Supplemental Gcode for Upgrades on Your Printrboard G2

If you have installed the Printrboard G2 and have already installed one or more of the upgrades listed below, you will need to add additional lines to the top of your Start Gcode in Cura.

Build Volume Upgrades

If you have a build volume upgrade on your X or Y axis, you will need to adjust the probe coordinates in your existing Start Gcode.  To do so, find the G1 coordinate lines in your start code and change the appropriate value.  In the first example, see a standard Simple (model 1403) start code updated to lines for a Simple with the X Axis Upgrade.  To see an example of the Play (1505) with Y Axis Upgrade, scroll further down.

In this example, we only need to change the second probe point.  It has been adjusted from "X140" to "X220" to compensate for the wider X axis.

Modified Start Gcode for Play (1505) with Y Axis Upgrade

In this example, we are going to adjust the Y axis build volume as well as change the first and second probe point.  The first probe point will change from "Y95" to "Y195" to compensate for the deeper Y axis.  The second probe point will change from "X70 Y45" to "X95 Y100" to probe the midpoint of the deeper Y axis.
