My 310 came with the error: "Axis excessive position error".
I replaced the timing belt, the servo, rebuilt the carriage and I still sometimes get that error.
The troubleshooting manual says one of the causes of the error is "Fast axis anti-rotate bearing missing". I would like to check the part, but I have no idea what it is referring to. Any insight would be greatly appreciated!
Also, does anyone know what a properly tensioned belt means?
