Issue with Bamboo CLT 470

John Z.
Hi everyone,
    I am experiencing weird issue with my CTL 470. The pad won't
    register the stylus movement, whether its floating or touching,
    until I tilt the stylus to be almost horizontal.
    Once this happens, pad 'catches' the signal and then, if I keep
    touching the pad and straighten the stylus - everything seems to
    work fine.
    The moment stylus stops touching the surface - nothing works again.

    I tried outputting events with xev, and IIRC - stylus buttons would
    produce same effect.

    I also tried to debug this myself (with xinput and xsetwacom) but
    none of the parameters listed here on in the man gave me no clue
    about the problem.


    Any help would be very, very welcome.



P.S. Apologies to killertofu for sending this email originally to bounce
address - should've paid better attention to what am I replying to.

Have you ruled out hardware failure? That sounds like a problem with the pen itself, or perhaps the tablet. Maybe also some interference. Anything metal on or near the tablet? Have you dropped the pen recently?

Hi,
thank you for responding!

I haven't, actually, ruled out anything. I was thinking hardware
failure
as well, I tried googling similar problems but ran into nothing, and
then decided to perhaps try here.

There's no metal around and the hardware was treated well, but it
hasn't
been used in a while. The only thing of note that I can think of is
that
some time ago, I changed the stylus tip, however - I tried removing the
tip and stylus behaves all the same except, of course, acting all the
time as if the tip is hovering over the pad.

In the end, it is their cheap-o line of products, you might be very
well
spot-on with the hardware failure :-(


[Don't forget to reply-all to keep things on-list.]

The best way to tell if it's a hardware problem is to try it on a different computer. If you have a Windows machine available, try it on that. If it behaves the same way, it's more than likely a hardware issue.

Now, I've done plenty of strange things to cheap Wacom tablets, including mounting a laptop monitor on top of one. The tablets themselves are super durable and resilient, so I'd be really surprised if it was the tablet that was broken. The pens, on the other hand, are actually fairly delicate. If you can find another pen to test with, definitely try it. Unfortunately, it has to be a pen from the same model line. They're generally not cross-compatible.
