M-400 error, can't update firmware for new screen - Dr_CRR - 03-21-2024
Hi all,
I have a Mars 2 pro, and have just replaced the screen with a chitusystems screen due to resin spill. I tried updating with the Elegoo firmware but the screen didn't work. I tried with the firmware available on Chitu Systems also which hasn't worked. When I try to print the update.SH4 file from Chitu (which a Redditor had a the same issue and theirs worked after updating with the those files), I receive an m_400 error and the z-axis starts spinning up, hits the top and doesn't stop unless I turn off the machine.
Does anyone have any ideas?
https://www.chitusystems.com/download/ - getting my firmware from here

Cheers,
