It looks ok to me. But my recommendation is to forget about the distance between the home switch and the centerline.
For example when I retrofitted the Mazak, I wired all the limits and home switches and when I was sure the hard limits worked I started playing around with the homing setup. Basically I relied on trial and error with the soft limits on the INI until the machine didn't hit the hard limits while jogging. So I set home position at the switch to be 0 (although that's not necessary, you can make that value whatever fits your needs) and from that position I carefully jog until I detect both positive and negative hard limits. Then I input that on the INI with some room to avoid overshooting and hitting the hard limits. The only difference is that your lathe is parallel so your turret feeds in the opposite way than mine towards the center, but that's not a problem since you already have that set with your motor's scale sign. So when you are in G54 and set your diameter or radius (I always work in diameter so I have G7 as one of my startup codes) you should see how your diameter decreases as you feed towards the spindle. By the way I'm reassuring this because reading your post got me thinking about how LCNC knows what's my turret's orientation. Hope what I wrote makes sense John. Take care.
