Hi all! I think I have finally successfully calibrated my machine and I’m getting ready to do my first cut. I have a stupid question however. When I upload G code, and it brings the project over into the preview window, everything is really squished and I can’t really tell how it’s all lining up due to the window. Is there anyway for me to resize this or zoom out so I can get a better picture of how it’s going to cut?

Try clicking on the center of the gcode preview area, it should cycle through a couple of different views

@bar This got modified when we changed the way we displayed items. Generating #810 #811 to correct.

You can try this one, could have other bugs, it’s still in testing.
