UPDATE: Thanks to a fellow member I have got this fixed. :slight_smile:

Can someone tell me do I change the settings from arduino icon or from Marlin because they both look the same. I connected through marlin and uploaded firmware but LCD is all blocks. Can someone please give me the answers to these problems thanks!

Hello! Can you please tell me how you fixed this issue? I too updated my firmware on my new Kossel delta and my LCD turned to a bunch of blocks. It also removed my heat bed and changed my hotend temp settings and gave me a fatal error, but I managed to figure out how to fix those. I just can’t seem to figure out how to fix the lcd.

Any help would be appreciated! I’m pretty new at all of this!
