Hi Ballendo,
most of the time the computer screen could be anywhere where you
could see it easyly while machining.
Ideal would be where you would not have to change your viewing angle
too much from looking at the cutter when jogging.
The controll Keyboard would be best to be opperated by your most
dexterous hand usually right hand this will give you the best chance
to hit the appropriate button or override when a emergency happends.
It should be close enough to be within reach while keeping a close
look on the cutter durring jogging but not close enough to get hit
by a flying chip durring machining that could trigger a unwanted
action.
Technically Home switches could be anywhere they do not have to
trigger zero ether could be any preset position.
It is usually easier to put them at ether + or - end of travel
to ease the determination of direction at startup.
They should be located at a position that is accessible even with
a part loaded.
This narrows the scope on a lathe because the further back on Z
direction may be blocked by the Tailstock on the other hand
a large dia. part on a faceplate may not allow access close to the
chuck end.
I guess a compromise that suites your typical machining envelop
may be needed.
Cable length may be best as short as possible to avoid electrical
interference with the drive signals.
When longer distances are wanted it would probably be best to do
some experimenting to avoid some bad side effects.
Good Luck
