I am totally new to all of this. I have read and tried to get it right but something is wrong. What is the right numbers to set on the input and output to get started? I have a new Townlabs Mill and anxious to make it run. TYIA. Ussca.................

There is not really such a thing, all will depend on which pins  you have the motors connected to , if you have limits and which pins they are connected to, if you have an E-Stop and where it is connected etc etc.

I found the problem. I followed the instructions and it all seemed to funstion, then the Y just stopped doing anything. I thought I had screwed up the config. Tried everything, Y would not move. Then yesterday I found the set screws on the Y shaft gear were not tightened up and that was the only problem. I had done it correctly. It seems to be dialed in now, Going to tram in the head tomorrow and then TRY and learn some g code and make something. Thanks for your help...............
