Topic: problem: wiring bundle getting caught behind the print assembly

When the print assembly try to home on Y axis towards the printer, the bundle of cable gets caught behind the X axis rail as it tries to move back to y0. See picture attached.

So -- how can I fix this?

Thanks,
P.K.

We could use a sticky thread for this question, it's being discussed in a dozen threads now. It'd be nice to have a single thread with the fixes people have tried.

This guy has a cool idea. Placement would be at the discretion of your wiring harness:

One idea that I had was to print a spacer that would slide on to the plastic tab that normally hits the limit switch so it would hit it even if the cable was in the way. This would obviously cut down on your overall build area though. The other solution is definitely better.

A common approach (for other printers) is to use a cable chain. Search on thingiverse for "solidoodle cable chain" for an example. (The mounting for that particular chain might not fit the Press though, but the picture gives some inspiration.)

Re: problem: wiring bundle getting caught behind the print assembly

This is the cable chain I just switched to on my solidoodle 2:

But, it works as shown only because my case has lots of room on top so I run the cables up above the rest of the print mechanism and down the back to the motherboard.

Re: problem: wiring bundle getting caught behind the print assembly

I partially solved my problem by twisting the black cable "sleeve". It seems to have a natural 'directioness", so by turning it a bit, it now naturally want to buckle upwards and does not get caught.

BUT now I have a different problem -- I cannot find a good way to route the filament as it gets tangled up with the -- you guessed it, cable bundle. I managed to almost print a complete simple model by printing with the "lid" up, and hand guiding the filament to prevent it from snapping. But obviously this is not a reasonable solution if the print time is longer than a few minutes !!
