Retrofitting a 1986 Maho MH400E
I did bodge up a spindle encoder and stepper mount to drive the leadscrew...
... but only hooked up a temporary drive and PC to use it to make the first back plates. I have been torn between CNCing it properly, like you did your Holbrook with two jog wheels on the apron to still do manual turning, or getting a set of change wheels and making the banjos. I rather enjoy manual turning on a lathe.
Now that you have you Holbrook finished for a couple of years, do you find you use the jog wheels like a manual lathe for those quick 5 minute jobs where specific dimensions aren't critical?

No, pretty much never as it is easier to use my turn / face / thread macros.
I do use the X mpg for parting, but I will probably make a macro for that at some point.
I thing you are right, g17,g18,g19 is a better way compared to separate configurations.

Most CAM systems assume that the tool is aligned along Z (and, in fact, LinuxCNC assumes that for canned cycles) to having the spindle aligned along the system Y can often be annoying.
I will quite often MDI stuff that way anyway, but if using CAM then I have to change config.
And then there is the question of arbor-cutters . I am not sure if any of the CAM systems are very good at that...
