i got the 2500 for a year now and my jog wheel now quits

ok, i used it exessivly scrolling through samples 1year

something inside is attrited i fell when i´m moving it

an the next problem now is when i´m moving it every 3third (unregulary) step

it does´nt react (the cursor is not moving or incr./decr.)

i hated it anyway from the beginning because it´s like a wheel from a toy

on this expensive thing

now my question is : is there something better to order to build in, or a

"jogwheelfix" like nym´s padfix on mpc1000 ??

i could use my warranty rights but then akaiservice will build in another

wheel like that and the same problem may occur...

thanks

Mine's doing the exact thing. Haven't cracked it open to unsolder it and check mouser.com for an upgrade yet, but I plan to.

Definitely NOT throwing the same part back in it, that's for sure.

Maybe we should hit up vst or that dude from mpc stuff and ask for the part #?

yo.

rotary encoders are frustrating. VERY easy to desolder and swap out (you do need a solder sucker, 5 bones at radioshack)

you're gonna laugh, but i'm on my 3rd rotary encoder since 2005. according repair folk, rotary encoders are the most common fixed thing they do there.

it's a pain because you have to actually take a whole board out of your mpc to fix it. again, it's easy, but my hands were shaking the first time (not anymore).

the good thing about mouser is that they'll be very cheap. otherwise, it'll run you about 15 dollars.

unfortunately, from what i understand, they don't make incredibly rugged encoders of this size. if you use your mpc heavily, they're gonna wear out.

i suggest finding the part number and buying a jar full of them to last you.

no clue. mouser has this nice part identification service though. they usually get back to you in a day. i'm gonna be scanning my old rotary encoder and getting my measurements but that wont help you guys that much.

sounds like there is no satisfying solution for this problem , is there no un destroyable steelmade encoder anywhere , i´m ready to pay some more money

if not:

king, could you please post if you´ve found the correct part at mouser

well, i use my wheel heavy and not too gently. i go through about 1 a year, i'd say, maybe a little less. it is literally a 15 minute process to replace, and very safe...while i'd love a real durable one that feels better than the ones i've got, it's not high on my personal priorities i'd say. however i'd happily follow anyone else's research and support them

I don't think the 1000 and 2500 jog wheel encoders are very similar. From how it looks like on the 2500 it might be much more complicated than just soldering out two pins.

Is the 1000 encoder like on the 2000/XL, Nym?

it's 5 pins that need to be pulled out of the 1000. either 3 are support and 2 or data, or 3 and 2, i dunno

a rotary coder tends to be a rotary encoder, just soldered into the board. it's not like the lcd screen, which is a much more big deal to solder in/out

this is what a 2000xl rot encoder looks like

they all look pretty similar.

I know what it looks like, I was curious if the 1000 one is similar. I'm gonna show you what the 2500 thingy looks like:

poor Stilo's posted this image a million times so thank you again.
Doesn't look like a standard pot style encoder does it? Ring/ dial style?

I'm checking out ALPS and mouser for something similar looking. I'll post up with what I find.

Any other pics would be appreciated too. Particularly a manufacture stamp and/ or the pinout.

By _Stilo_ Tue Nov 20, 2007 7:23 pm
:lol:

Here's another shot...the stamp on the metal says "ALPS" and "55". I think it really only has three pins just like the ordinary rotary pots.

hah, look at that son of a gun...thanks, stilo, for putting that up, very interesting.

just from looks, it like a more rugged device than the 1000's, but i don't think it'll be any more difficult to desolder. luckily.

you WILL need a solder sucker, otherwise you're gonna have a connected mess when you resolder those 3 close-together pins on the left
