Newbie stepper kit

Hi magicniner
Maby I should not have asked, Sorry for treading on some CNC toes
I am not dead against CNC software, my machine (Optimum MB4) is just not a CNC machine, and if you google DIY Motor for my Z axis or something like that, you will find all kinds of solutions for my type of machine with hand cranked Z axis where the DRO is installed and also a quill), I just would like a motorized precise way of operating my Z axis (if possible) with locked quill, because using the quill is just introducing another wobbly factor to a not already super sturdy machine.
Forgot to say that hand cranking the Z axis is difficult for me because of fycical challenges, I got a motor on it already but I cant stop it percisely where I want.
Kind regards
