Recently, I have been tasked with printing a 12" tall object, as you know my Prusa IV3 prints at 300mm which is slightly shorter than the 12" I need.

I have been experimenting and have lifted my X axis up to 300mm and have found that there is more room for it to travel. However, I cannot get my machine to move past 300mm which I assume is a safety feature.

In order to fix this I have change my build volume in Simplify 3D to 310mm as the Z max. However, I still cannot move my printer above that 300mm mark. I then looked in the configuration.h file on the firmware and cannot find a place that limits the build volume. Does anyone know how I can up my Z-Axis limits?

Thanks.
