Hi,
how about just answering the question....have you programmed the HLFB? If so what is it programmed for?

Start at the beginning, then worry about the RJ45 cabling. Just changing things without any sort of plan is going to waste a lot of time and money,
start at the beginning and work your way through it....and it all starts with the HLFB.

I don't know just trying to help out a friend he bought this machine
was not consulted when he bought the machine
I have not did anything to this machine except to try a new cable on the X axis
there is no documents with this machine
I am just trying to help out a person in a bind

Hi,
well then you'll have to download the Clearpath manual, its freely available, and install the set-up and tuning software on a PC, and
at the very least interrogate the firmware to establish how its been programmed. It may well be that the HLFB output has never been programmed
and that would certainly explain part of your issue. You can also interrogate the servo with the PC and find out things like Following Error.

Your friend has no doubt paid a premium to get a machine with servos.....now is the time to dig into that capability.
