Carriage cable flopping about

[Vinyldog]

So I’ve installed a new carriage cable and guides on my SP540V and the gap at the curl looks identical to the illustration in the service manual. But at about a foot after leaving the cap station the top guide separates from the cable and bottom guide, then they all start to flop about. It’s as if the bottom guide doesn’t want to slide along the channel but the surface feels very smooth. I’ve tried tightening and loosening the cable with no better result. I don’t think the cable is moving inside the guides as it works because the gap doesn’t change after use.
To be clear, it does work for awhile but then eventually binds up, so now I’m wondering if the cable has not just become too kinked to function.
To avoid replacing the cable again, I’m considering binding the cable and guides together about a foot from the carriage in an effort to keep them from separating and hopefully force them to travel down the channel more smoothly. Just wondered if anyone else had tried this.

How is someone supposed to help if you don't put the machine you are using. Also who is Service Manuel. Is he your Mexican service tech?

SP-540v in the first sentence.

You might try applying teflon tape to the metal rail and are the plastic mylar guide rubs against. It is also possible the plastic mylar guides were not installed correctly, or the white ribbon cable is too tight or does not have enough slack. A little difficult to explain... First thing, power off the SP-540V and unplug. Then manually move the cut head back and forth to see if you can pinpoint what is causing the bunch.

thank you or your interest and especially that link to the Teflon tape. I began looking for a product like that last week and all the retail stores kept sending me to the plumbing department for thread tape. I did finally find a product on Amazon called UHMW tape which seems to have very similar properties.I'm not sure how it compares to the PTFE but I will have to use it because I can‘t afford to extend the down time any longer.
In defense of Mr Easy I did edit my post after he pointed out my discrepancies.
