Boxford 240 home switches?

[X3Chalk]

i think the boxford software used to use the physical stop of the axis to set the home position before they went over to sensors.

Thanks, I feared as much.
Does not seem best practice, but also method used on the Turret.
On the 160 I had to replace the turret stepper and considered the misuse, together with age, as a possible cause of it's demise.
