Thanks for the share Dave, the USB lead looks a bit pricey if you ask me, should get that with the drive no?

Looks a good option to me!

Mainly because No Isolation on Analog. But other smaller niggles are No RPM readout only Khz. Only 12Vdc output not 24Vdc for controlling external devices And I'm not sure but think it doesnt have onboard relay but been while since fitted one so may be wrong.

Then in general didn't like the build quality and the Manual was Crap.!

Huanyang Vfd's have got much better in recent years and now come with half decent paper manual. However they still have longway to catch up with likes of Invertek or IMO etc.

KK, I'll email them now quickly and ask if its a gen Huan or not, though I quite like the look of the Invertek from Joe now I've seen them, I dont think the spindle's on their own cost that much now days do they, could be a nice investment if I was to pair them up using the 4 bearing version?

You'll have to go first then Joe, as i'm not that far in to my build yet

Looking good! I'm glad my schematic helped initially - I won't feel so bad now when I shamelessly rip off most of yours! You have definitely taken this to the next level! What are you using for connectors for your cy cable? I have struggled to find ones that allow connection to the shield...

Haha thanks Joe, I would have been clueless without your schematics and I cant say the same for when I shamelessly ripped off most of Deans setup!! I haven't even started looking at the cables/wires yet so got all these problems still to come!

On the topic of wiring, I found this when searching around which might come in handy for others as it sure will for me! http://www.mycncuk.com/threads/6322-...4x4-cnc-router

These are in the UK and not too bad on price Chalon's RT18 DIN fuse holders I've found that Chalon are good value and you get good service from them, or at least I've had good service...

Why in most cases you are trying to use fuses? Because they are cheaper than circuit brakers? Is that the main reason?

I think most use circuit breakers on AC and fuses on DC...
