Thanks for your reply, the Mach3 lathe version that downloaded in February and which I'm using, is R3.043.066 !

What exactly am I trying to achieve with pulley ratios, well I'm just following the manuals recommendations. As there are six pulley ratios available on my lathe it seems to make sense to have them installed and ready.

It does not seem unreasonable to me to expect, that after marketing this product for so long, the company would have at least amended the manual to reflect the software version that is downloaded. And no, I don't buy the argument that it's free so take it or leave it, as it's not free when one has purchased a licenced copy.

Having many years experience with Fanoc, Yasnac, Haas and Mitsubushi controllers, I'm not impressed, Mach3 lathe does not even support G70 G71 G72 G73 which are fundamental to any turning operation.

Rant over.
