There are grey scale absolute rotary encoders that are fairly cheap. I think those would be a better test than linears since you have to handle the wrap around accumulation. It would be a simple case to use a linear encoder if the rotary worked. Stephen

Hi, Just wondering if there's any experience with absolute encoders and LinuxCNC? And particularly absolute linear encoders, with or without LinuxCNC. Thanks, Andrew -- Live Security Virtual Conference Exclusive live event
