Might be worth running through the difference in inherent capabilities between an ELS machine and a manual / CNC (or “teach”) lathe for the benefit of folk who may be considering DIY upgrading to either full electronic control or full CNC in the future.
Despite the apparent overlap in capabilities between a carefully driven ELS lathe and a “teach” style machine basically running point to point by loading cut start and end points the mechanical (and financial) issues to be considered in upgrading are probably considerable.
Heck if it were that simple there would be no market for an ELS lathe. Might as well make a manual electronic CNC “upgrade ready” lathe for “a few £ more” and be done with it.
