Re: 800w Chinese spindle

One of the pluses I've notice about using a air cold spindle for me is the fact that air is drawn in at the top and out the bottom of the spindle, as I don't use a vacuum when cutting the air from the spindle blows debris away from the cutting area. (see attached videos) Note: the phones Automatic G...

Re: Chinese spindle (the 2nd best thing I've done for my Sha

I was just wondering where you sourced your spindle mount from. I went ahead and got the same spindle based on your recommendation. The thing is a beast and I wanted to be sure that I got something that would be up to the challenge of holding it in place. I made the mount myself, it's nothing speci...

Re: Hall Effect Sensors as Limit Switches

RobCee, As I double checked your Schematic I find myself questioning D1. What is it's purpose? Are you using it as protection for the Arduino inputs? ... The D1 (diode) is there to stop the other LED from turning on by limiting the direction current can flow. If you do not have the diodes in the ab...

Re: Chinese Watercooled 1.5kw Spindle

I earthed the cable shield at the VFD into the earth terminal and ran a 6mm earth (its a over kill in size, but its what I had laying around) to the back of the spindle mount. I ran the earth and spindle inside some sexy heat srink braid heat shrink braid http://i34.photobucket.com/albums/d104/htpc_...

Re: Chinese Watercooled 1.5kw Spindle

The spindle its self does not need to be grounded to work but it should be grounded for safety, As for shielding... there is no need to remove the plastic coating because shielding is only protecting against "radio" noise which pass thought plastic, now for the connection of the shield... for best r...

Re: Chinese spindle (the 2nd best thing I've done for my Sha

After having the spindle for some time now I can say I'm still happy with it... But there is one big fault in it and that is the connector used on the spindle, I was suspect of its voltage rating from day one and it turned out I was right. As you can see from the photos the centre pins were arching ...

Re: Chinese spindle (the 2nd best thing I've done for my Sha

How slow can the spindle go? When it goes slow, do you have any heating issues? There is a mini speed for the spindle, I think it's about 100hz ( http://www.etech.net.au/Huanyang/Huanyang_English_Manual-c.pdf ). No I have not had any heating issues. Have you tried a 1/4" or 6mm endmill? Can you tak...

Re: Chinese spindle (the 2nd best thing I've done for my Sha

Hi, I am doing some research about the spindle I will use in my shapeoko. I am very interested in these spindles that they sell on ebay (like yours), so I would like to know how is your doing. You have it for some months now, is the machine holding up well? I am going for a dual motor drive and dou...

Re: My pursuit of the perfect Electronics Enclosure

...I didn't want to spend 70 dollars just to cut off 18 inches of rail... That’s fine… we all have preferences how to do things, But I have no idea where you have got your unit costing from? http://www.rs-components.com/index.html is just one of many world wide supplers ----------------------------...

Re: My pursuit of the perfect Electronics Enclosure

I would go with DIN rail terminal blocks, you can link as many or as little you like and come in different colors/sizes e.g Green/Yellow for earth. They are used a lot in indusial installations and all you have to do is cut some DIN rail to size to fit with in the case, once the rail is cut the bloc...
