Electronics peeps; my sampler has an issue where the rotary encoder drops inputs, registers multiple for single turns, or registers inputs in the opposite direction. Does the encoder need replacing?
Okay managed to find an applicable service manual and that's given the item code EC24B50D0, which doesn't come up with anything in a search but it has confirmed what I know.
The question now is what to get as a replacement. How are "detents" measured on rotary encoders?
@renbymon sounds like the encoder I replaced in my trackball, could give it a scoosh with contact cleaner though I would budget for a replacement soon.
@renbymon Likely yes. It's a shaft (hurr) with 2 disks on. It'll either be contacts or slits with an offset. So it measures time between seeing slits and works out how far/fast/which direction.
SOMETIMES Contact cleaner/other solvents can wash the crud out enough. But oftentimes it's just easier to replace.
The difficult part is matching the various parameters up o.< So you have to strip it to find the part number anyway >.<
@Jencen Thank you ^^
@Jencen This is bigger than I was expecting! The base is about the size of a pound coin.
@renbymon assuming it worked correctly before: yeah sounds like it needs replacing.
(For DIY electronics, there could be other things like a bug in the programming that causes it to not read the encoder correctly).
@ayke It's an AKAI CD3000XL sampler, made in the 90s, so it's going pretty well considering that only one button and this encoder are faulty. :)
@renbymon could try hitting it with some electronic contact cleaner.
Follow up, does anybody recognise this rotary encoder and where I can get a replacement or equivalent?
