Yes this is a old tread.
I am new and looking and I am looking for a replacement for the Encooders. I have a Tin Lizzie 18 I pick up and it is missing the encoders and wiring. It have the "head" controler and the back of the machine has the old sytle mouse plug in.
Looking around, a replacement is pricey. So I am looking at options.
Looking at laser type so I don't have to build mounts...
