Heatbed Assembly 4.27 Covering Heatbed Cables

There is a significant gap (2mm+) between the bed-cable-cover top and bottom covers when I run all the cables+textile sleeve.  I neatly run the cables and angled in a 'V' as directed, but only way to fully seat the covers would be to make relief cuts.  Any tips on routing this so the covers fully seat with no gap?  I don't suppose it is a significant issue but rather have it fully seated.

Take a look at how I do it in my video guide (link below). Are you following the same?

It can indeed turn into an issue if the upper cable cover sits too high: If you want to use the rear left area for printing, the air duct on the print head may collide with the cover before the nozzle reaches the print bed. So the initial bed probing will already give incorrect results.

In my Core One kit, the heater cables were bent upwards a bit; I had to bend them down to avoid an interference with the cover. Some users have also reported that they used different screws (with a low-profile head) to attach the cables.

Indeed. Prusa changed their instructions sometime around July to use a flat-head screw rather than a button-head that was previously specified.

Thanks for the suggestions, a combination of bending the terminals slightly downward and adjusting the textile sleeve so that it just clears the entrance about 4mm helped and I was just able to seat the covers.  Thank you!
