Maschine rotary encoders dying


Recommended Posts

Hopefully one of our resident techsperts can help.

 

My Maschine controller dates back to the product's original release and one of my rotary encoders is really playing up, causing whatever it's controlling to jitter around on the screen until I give it a few more random twist to settle it down.

 

Can this be cured with lubing? Any ideas what lube?

 

If lubing isn't the answer does anyone know the spec of these encoders and where I might get more from? I've got someone who could change then for me if I can find the relevant part.

You can sometimes fix dodgy rotary encoders by spraying contact cleaner into them and then turning them a few times, but usually they need replaced. This is probably the stuff you want : http://www.maplin.co.uk/p/servisol-contact-cleaner-200ml-jp17t - although any spray-on contact cleaner should work (not WD-40!)

 

MPCStuff has *used* maschine rotary encoders for a frankly ridiculous $20.00 ... - http://www.mpcstuff.com/nim-pot.html

 

...But they look like fairly standard 12mm encoders (which all have near-identical PCB footprint), so I'm willing to bet something like these will be interchangable : http://www.amazon.co.uk/10Pcs-Rotary-Encoder-Switch-Keyswitch/dp/B0085I4D5C

 

Or if you're feeling brave you can try dismantling the encoder and cleaning the contacts directly.

Jimmy - cock off funny man!

 

Rasteri - thanks mate. I've got some of that servisol spray somewhere from years ago... failing that, I think the Caig Deoxit I use on fader rails will do the same job.

 

MPCstuff is always pretty ridiculous IMHO. They make there money selling cheap parts to people who don't know any better and are afraid that stuff from general suppliers will work I their machine.

 

If lube/cleaner doesn't work I'll have to open it up and try cleaning the contacts or working out the spec and replacing it.

Thanks Matt, but I think it is just the encoder as its the top left one which is used more than the others and has steadily declined in the last few months.

 

Every once in a while the master turns itself to 0 for no apparent reason though - this could well be the USB.
