Cancel the encoder IF you order the above.

You are putting us ( especially me ) in a very bad position, unintentionally i am sure, but still a very bad position. You have to read and follow our advice, otherwise you end up with lots of useless stuff and lots of waisted money.
Case in point, i did say to remove the tacho from the Z axis motor ( the small thing with 2 thin wires on top of that bigger thing with 2 wires going to 4 connectors on the motor on the attached picture of the existing Z axis) and measure the shaft, then and only then, order the encoder and a coupler with the right shaft diameter for the existing motor and the new encoder.
You just went and ordered an encoder.
Hence the above list., as it will make it easier to set up and less chances of mishaps, but it will cost more.

Some friendly advice:
-take it easy, read a lot about everything we mention here, and most importantly do not act until you understand why or how,
-ask here about everything that is not clear or obvious, ask a lot,
-you will be dealing with a machine that uses power to function, lots of it, so inherently they are dangerous, especially the electrics/electronics parts and any mistake can ultimately void you of your life, so no rushing there, there is no "i am sorry" when working with these types of stuff, the result will always be lots of burned/damaged equipment and/or injuries/death.
-this will take you much more than a day or two to finish, more like a month.
-i have done over 15 retrofits of big industrial machines, so i have plenty of experience and that makes it sometimes hard for you to understand what i am trying to say, so if you think something is not right, please do write immediately, do not hesitate.
Regards,
Tom.
