Hey Guys,
On one of my UM3 machines i started getting ER18 issues, so i did what i had to do for another machine - reseated the cable, made sure the white cable was pulled down, used a shim etc.. that has always previously worked fine on some of my other machines.
But it still didnt fix the issue, so i ordered a new cable and just installed that but im still getting the same issues.
What else can I try?
