Tried it but…

[John-SC077]

I loaded this firmware on a 5M Pro, installation worked fine. First - what are the user and password to ssh into this? I cannot find that information anywhere. Second - after the startup I tried to print the small calibration cube and it prints the outline but when it starts the bottom surface I get a "MCU 'eboard' shutdown: Rescheduled timer in the past" error.

Using Simplify3D, I have tried slowing the speeds to half of what I used on the original firmware. What can I do short of replacing the main board in this?

It is reported right in the README of this repo
