KAT2 Bump

[Matt Palmer-4]

@don and the other guru's

KAT2 is built, however i cant get the 10pin connector to sit on p4 of
the control board, i dont want to force it, (right now i'm pushing
enough to flex the circuit board) is it supposed to sit flush or nott?

Matt,

It does sit flush when fully seated.  You may have one of two problems.  
The first thing to check is your soldering of the individual sockets to
the wires.  If you allowed solder to wick up into the socket area, you
have plugged the hole for the pin and it will never fit fully on - it
only takes one socket like that to cause fit problems.  The solution to
this is simple (but not easy) - remove the soldered on sockets from the
housing (it takes a small needle-point to depress the little tongue) and
replace the troublesome socket with a different one.  To find any
sockets that are solder filled, test each one for depth with a cut-off
component lead - it should insert at least as far as the length of the
pins on the header.

The problem also could be that you inserted all 10 sockets into the
housing - just like the manual instructed, so great for you in following
the instructions! , and they just are not fully aligned yet.

The fit with all 10 sockets installed is tight because all those
connector sockets are new.  They will give some relief after a few times
on and off the pins.  You can plug one row of sockets onto a row of the
pins by offsetting the connector to one side and plugging it in (Be
*certain* to remove the power from the K2 while doing that).  Do that on
both sides - you might wiggle it back and forth a bit too to loosen
things up and get all the sockets into alignment.

It will go on all the way once all the sockets are properly aligned and
are pre-sprung.

I found I had to force this connector on and that it wouldn't seat
completely.  It appears to be the design of the contacts, which
completely surround the pin and don't have room for expansion at the
entry to the contact. I was concerned about stripping the plating on the
pins after a few cycles.

However, I also bought the KIO2, so now this connector goes into the
KIO2 connector board and the PC mounted female connector on the KIO2
connector board has a contact design which doesn't have this problem.
