Title: New keycaps.. Backspace bottoms out fast.
Post by: stancato9 on Tue, 29 October 2013, 22:31:59
Just got a set of keycaps from banggood.. white pbt. First off the spacebar is extremely bent to the point where it is very gritty and completely ruins the feel of my MX reds.

Also, the backspace keycap seems to make the key bottom out very soon. It travels less and bottoms out before all the other keys. When I switch the keycap it is fine. It is also super clunky and hard to press unlike any other of the keys with stabilizers. Does anyone have any suggestions as to what to do?

What stabilizers are you using them with?

Sometimes pbt can warp a little.

Cherry stabs. Yeah I know the spacebar is warped, I can see it really clearly but the issue with the backspace is really confusing me.

Maybe the backspace is a little warped also?

It looks pretty good to me. When I set it down on the table all 4 corners are touching. If it is warped did I waste money? What can I do really

You can fix a warped keycap pretty easy.  You can heat up the keycap by putting it into hot water or use a hair dryer to heat it up.  After you heat it up, put some heavy stuff on it.

Bent PBT space bar is fairly common.  As jonathanyu suggested, put it on a completely flat surface, heat it a little with a hair dryer, then put a heavy book on it for a while.

For the backspace, are the stems in the right place?  Sounds like one or two might be off-centre or bent.  Look underneath and compare with the old backspace.  Even half a millimetre would make a difference.

I will try that. And yes, the stems look like they match up fine with the old backspace. To add to it, it's quite hard to push the backspace key on. It feels like its grinding.

I also just tried a Filco OEM backspace key and it appears to have the same problem. But the Poker 2 default keycap and a QFR backspace are okay. Weird.

Actually, they all don't feel completely right, though the two I mentioned are a lot better than the others. Could it be a problem with the stabilizer itself?

I just tested the switch with Canadian nickels and it took 16 to actuate it. Weighing 3.95g each, that's a total of 63.2g for a cherry mx red switch.

Compared to 39.5g to actuate the "A" key and 35.55g for the spacebar.

Got mine today also. The backspace does have a very distinct clack which can be disturbing. My spacebar has no problem, though.

60+g to actuate an MX red does not sound right.

Can you try a 1x keycaps on the backspace switch and see how much that needs to actuate.

If it is around 40-45 then there is a problem with the stabilisers.

If it is still 60+, then it is a problem with that switch.

I can't get a 1x1 on because the stabs block it.

Can you sacrifice an old 1x keycap (this is where having a Crap Bag comes in handy) and shave the sides off?

Unfortunately I don't but the switch feels perfectly fine when I depress it with my finger.

Sounds more and more like a broken or misaligned stabiliser.

I'll probably just buy another stabilizer and switch it out although I've never soldered in my life.

if the stock caps work I highly doubt its broken

Post by: stancato9 on Wed, 30 October 2013, 19:55:32
Well like I said above the stock caps work better than my new ones, but it has always felt very stiff as opposed to the other keys.
Title: Re: New keycaps.. Backspace bottoms out fast.
Post by: rowdy on Wed, 30 October 2013, 20:27:03
Did you test the actuation point with the stock keycap on?
Title: Re: New keycaps.. Backspace bottoms out fast.
Post by: stancato9 on Wed, 30 October 2013, 20:42:51
Just did 51 grams. Which is still a lot higher than the other keys with stabs. Not is it just harder to press but it doesnt feel smooth at all.

Did you have a hard time getting the backspace key off originally?
Title: Re: New keycaps.. Backspace bottoms out fast.
Post by: stancato9 on Wed, 30 October 2013, 23:17:08
Nope.

Post by: rowdy on Wed, 30 October 2013, 23:36:25
Sounds to me like the switch or stabilisers are not in properly or are damaged, and that some keycaps have a greater tolerance of the misaligment than others.

I will guess the wire has become unseated slightly on one side of the stabilizer. You should be able to get it back in with a tiny screwdriver or something to push it back in place. When it's out of correct position it will cause much more friction or binding.

Like some of you suggested, I heated the spacebar with hot water and put it under a weight and now it is straight length-wise, it is all messed up. The weight pushed the sides out.

Perhaps a little too much weight was applied.  Oops.

Yeah, figures. Oh well. I am contacting banggood for a refund or something. But I'm going to take a guess that their customer service won't care.

This is really weird the backspace feels and fits fine on my QFR with blues.

Some stabilizers aren't spaced exactly right, and some stabilizers work with slightly off key caps better than others.

So what would you suggest I do?

Sounds more and more like broken or dislocated stabiliser.

Have you tried Ivan's suggestion: http://geekhack.org/index.php?topic=50278.msg1097488#msg1097488

I can't see anything wrong with the wire. It's on a Poker 2 so I don't have access to the stab without desoldering.
