Hi,

I have a question about water pump. What is the size of the coupling for the hose (pvc 6mm one)? Where I can find this?

Thank you
Gabi

Hi !
The pipes I got with my kit were PVC 6mm. However, I do not recommend those. Personally I find PVC too rigid and prefer much more plastic hose used in gas powered remote control airplanes. If there is a store close to your house that sell that kind of planes, just get it there. It's quite cheap. Otherwise you can order it online :)

I have the pipes. my question was about the connection. The brass connector.
On mine (pump) the seller said is 18mm diameter outlet. I cant find anything with that dimension at one end and with 1/4" or 6mm on the other end.

Weird :/ Mine is different. It's made of plastic, exactly like the one on this kit:

Though I have to admit it was quite hard to fit the pipe that came with the spindle. The coupler I have has the same size as the one on the spindle.

Many of you have the same setup. Where do you find the connector?

Not sure what your asking here . ? . . . The pump in the picture doesn't need or use a connector it's got a Barb so you just push the pipe on and clip it.!

If your wanting the Barb Fitting that screws into the pump then try these people.

Hi JazzCNC,

The photo is for reference only. My pump came with a bigger plastic connector. I will have a look on that site.
Still maybe know where I can buy the right one. I bought the 3/4" barb and doesn't fit, it is a hair big...

Thx

Got some Noob questions. Thanks for any help.

1. Can anyone confirm if its safe to power up the VFD without the spindle connected for setting the parameters at the beginning ?

2. I have already purchased 3 core foil shielded Belden Cable for my spindle.
http://www.ebay.co.uk/itm/111817521022
Is this ok ?
I just read i was supposed to use 4 core CY Cable.

3. Do i have to earth the spindle at the spindle end by removing the top and making a ground point and connect to pin 4?
E.g. Should I have 4 core cable as well as the shielding ?

1. I believe it is ok to run the vfd without being connected BUT do not connect or disconnect with it powered up.
2. Yes it will be OK CY cable is generally used but you have already purchased it so use it.
3. It is ok to earth the shield at the VFD end only, 4 core is not a necessity .

Just to clarify, this is true for the shield but you should ideally also earth the body of the spindle, not relying on earthing through the machine frame as the bearings are not predictable.
