Answered C2 HDMI Ribbon Cable

Moved to the C2 section (this was in the R1 section)

 

Is the existing cable damaged?

 

26 pin ribbon cable I am pretty sure, but I am not sure I remember if both ends are female or not.

That should be the one, I popped off my front cover and there is indeed a 26-pin ribbon cable attached there. The BAD part is that it is NOT connected like a normal ribbon cable and in fact is TWO ribbon cables (which is an odd way to do this).



Here is the other end on the PI:




Like I said and odd way to do that rather than use one cable.

 

Oh, that:

That looks like the camera cable.
Pretty sure the display connector port is the same sort of cable






You can get those in a variety of lengths from Amazon

 

BTW: While you are in there you should add a camera (I did) it is not hard.

...and (for what it is worth) I just don't have that cable at all
Mine totally works only from the Pi GPIO (not sure if that is evident from the pictures or not)

 

Fixing the problem:

Try reseating the flat cable into the adapter like this:

Flat cable seated into adapter, but not secured


Flat cable secured in the adapter


OR

Try ordering this replacement from Amazon.com

OR

Contact Robo tech support if your printer is still under warranty.

Your choice!

 

They may (or very well MAY NOT) actually have parts, but worth a call if you are under warranty

 

Good, keep them honest
They need to handle warranty items.

 

Amen to that!

 

I had to order one for myself. I had taken apart my C2 printer in order to get the photos taken. Almost didn't get the C2 printer working once I placed the cable back into the touch screen.

 

Yes it is working, however, the next time I remove the front cover, it probably will break.
So, I now have the fix on hand waiting for that to happen.

 

Update:
I replaced the HDMI cable to the touchscreen using the previously posted part link. Two recommendations based on my experience:

1) the replacement part from Amazon is slightly shorter than the original cable. So, attach the touchscreen end of the cable when you are closing up the C2 printer.
2) use a small screwdriver to temporarily lift the saddle cover nearest the HDMI cable so as to give additional clearance as you re-seat the front cover. Pull the screwdriver away once the HDMI cable clears the saddle cover and then snap the front cover into place.

An alternative method for #2:
Lift the saddle cover for around an 1/8 of an inch (2-3 mm), close the front cover 90% (until the HDMI cable end clears the saddle). Then re-seat the saddle cover and finish snapping the front cover in place.
