Well here goes... Aluminium frame router design

I'm running my Nema 34 on a 230V Kinco driver and at the moment it's running on 10 m/min rapids and very happy, had it on 15 m/min and was still happy but don't need that sort of speed. I got the 40 tooth pulleys as the Nema 34 has bags of torque and I wanted as much tooth engagement as possible...

I've not noticed any whip on change of direction...

Neil I thought you had used 230V but when I looked at your schematic I saw three drives connected to the PS did you originally go with nema 23 all round?

I've got an AM882 driver for a 4th axis as well now but did originally plan to use a Nema 23 on all axis as the calculator showed I'd be able to use it on the X axis but I decided to play it safe and go up a size.

Ah! that fooled me

On the schematic it only showed the two AC wires that were going to the driver, don't think I even put a representative box on it....

I looked here but didn't notice the 230V drive. That will teach me to assume. ..Clive

I have been looking at the nema 34's and I am confused about the specs..
They all seem to quote a recommended voltage of about 2v, whats that all about? Would one nema 23 just not be able to move the mass because the 34's are quite a bit larger and wont fit in the location I have put it, which means putting 2 nema 23's one on each ballscrew which then also means a controller which supports slaved drives and controllers with error detection which means £££ ! I am trying to sell this to the better half as a bit of additional income but when I mention a couple of hundred pounds extra on top of my ever increasing budget she doesnt seem very impressed, I don't know why
