Re: Encoder requirements for the Acorn board

Finding a mill that has a readily accessible mounting location for an encoder is not easy! That is one of the reason I chose the Grizzly 0678 over some of the "better" mills on the market.

Here is how I mounted the encoder:

I hope those pics show enough to help!

Dave,

Thanks for the photos. My milling machine should be delivered in the next couple of hours.

I may be able to attach a timing pulley to the top of drive pulley. It will require a large pulley so I can bore a hole that will allow for the drawbar and mounting screws to attach the encoder pulley to the drive pulleys.
