I just a V8 hit my head LOL

Hello I have a Ender 3 Pro and I just install Ender Extension 300 X 300. My Cura V4.11 So I enlarged curas bed to 300 and designed trackwork for sliding workbench doors. I had printed them up smaller before on stock 9" bed. but I had to redesign them. I increased to 10.5" to try new 12 X 12 bed. I was wondering why it looked like print object was looking "cut off" on one end. maybe Ill try one of original files to see. Well what I cam to relise is I still have original 8bit board in my ender. I could find a setting in the Ender to change new bed size. Guess I'll be installing SKR 1.4 pro sooner if I want to take advantage of 12 X12

changing the bed size in the slicer should be sufficient.

But you can reflash the firmware with the new bed sie in the config.txt file to embed it in the firmware.
