Hi

Thanks all, exactly the info i needed, i was not thinking about these

The Nema24 motors are 4mH/phase and ideally need 60v but are shipping with a 36v supply and 42v drives . The Nema23s are 3mH/phase and ideally need 55v and ship with 38v supply and 50v drives.
and

Now the thing you don't realise is that what's important is the Inductance rating and often the larger 4Nm motors have much higher inductance than the lower 3.1Nm and this means they don't perform has good.
are both important bits of info, dont you just love proper hobbyist forums

Honestly I'm not just being Negative or pulling down
I like direct answers like that, and am listening and reading.

Now it seems to me your Rushing and not really knowing what your buying or what Mass you have to move.
AM not rushing, but am eager, i have the funds in the bank.

The gantry i have planned will be below 40kg, fully loaded, probably closer to 35kg, I know how i will do the gantry, but have not finalised the design, as i need to think about what i might need to strap on to it.

I want to incorporate a turret on the end of the table, and a rotary table or b/c head on the table. and a geared 4th axis

I'll PM you my number if you want to ring me and I'll try to help.
.

I will write up fully on here what am doing and mp you, thanks.

Thanks to all of you for your replies,
