Mach3 lathe spindle pulleys problem

[m_c]

I was always told that I would not be able to thread successfully with Mach but it looks like I will just need to discount pulley ratios too.
Will just play a while with what i have then look at changing to linux. I chose to keep Mach 3 cos i was familiar with it , but looks like it falls short on a 64bit operating system.

Thanks for inputs anyway.

Mach 3 can produce perfectly acceptable threads.
Only thing that won't work on 64bit, is the parallel port driver. Mach itself still works perfectly fine, you just need to use an external motion controller.

I use an external motion controller (UC 100) so am still exploring the options here .
Trying the wizard but it it comes up with an error message saying that no lead is specified in the G76 commend so am looking into that now .

My PC is 64 bit with windows 10 and connected via the UC100 controller to USB port .
Are you saying I should still be able to change spindle pulley ratios and cut reasonabe threads with this rig . If so what settings do I need .
