I am new to 3D printing. I have a Robo 3D R1+. I use Matter Control for slicing. I have been using a Rasberry Pi to be able to monitor the printer remotely. When I first set up the Pi I was able to do a few prints just fine. Now when I run the prints directly from Matter Control it is fine. However, when I run though the Pi the Z-offset is not right and it is printing way too high. I do not see a place in Astrobox to change the Z-Offset. Does the Z-Offset get saved in the G-code when I export the file? How can I fix the Z-offset when using the PI.
