Hello,

I've physically extended the Z height on my prusa i3 to be able to print 12inch high parts. I'm changing the settings in the "options/machine tab" to 305mm. I'm also making the adjustment in the process i made in the "G-Code tab" in the "update machine definition" section to 305mm. Unfortunately when moving the extruder manually, i cannot go past 190mm. It does not work either if i try to print something higher than 190mm.When i change the build volume, I can see the update being made in the viewer where my part is. I see the virtual build box being updated.

Can anyone help?

It sounds like your firmware still has max software endstops enabled at the old 190mm height. You will need to edit your firmware so that the Z_MAX_LENGTH is the correct value or set max_software_endstops to false.

Thanks alot! It was indeed a change in the firmware.
