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

...How much does yours weigh? Are you on 110 or 220 volts? -The spindle itself weighs about 6Kg -I'm on 240 (Australia) but you can get VFDs that work at 110 or 220 ... This does not seem to be too much power for the ShapeOko? I did not imagine it could handle 1500W.. :o -You just have to work with...

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

...Can you tell us more about the price and the runnout ? What kind of material did you mill already ? Aluminium ? ... -This is the one I have, You need a controller to run it as its a brush-less 3 phase motor (note: you can get a water cooled one about $100 cheaper if price is a major factor) -The...

Chinese spindle (the 2nd best thing I've done for my Shapeok

After some time thinking about moving on from my rotatory tool and looking at options (Kress vs Chinese spindle) I when with the Chinese spindle based on noise level and form factor. I ended up picking a 1.5kW air cooled spindle with ER11 collet from ebay. I've been very happy with it – it cuts some...

Re: GRBL Freezes while sending a file

V+ and V- are terms used in DC because these points are “floating” voltages, this basically mean these points are not references to anything e.g “ground” and can be used in a positive or negative potential. Earth is a term used in AC (mains) or site protection and its' main purpose is safety, for ex...

Re: Backlit cedar box, LED help please.

..what are the minimum trace widths and spacings you have been able to mill? ... I've easily done down to .3 trace and would not see much of a issue with 0.2 traces, I'm using a 0.5mm end mill thought so that is the minimum trace spacing/isolation I can do. In saying that I tried a few times to mil...

Re: Backlit cedar box, LED help please.

You really need to pick your LED first as different LEDs have differed forward Voltage/Current, these two thing are used to calculate the best resister to use which will give you the maximum light from a LED. http://ledcalculator.net/ Another thing to note is that the LED forward current must not be...

Re: Electronic Enclosure

No I don't really have any issue when transmitting on Xbee or Wifi as I've moved the Antenna on the Xbee to be external (made my own SMA lead) These are the connectors I've used: http://www.jaycar.com.au/productView.asp?ID=PP0544&form=CAT2&SUBCATID=990#1 http://www.jaycar.com.au/productView.asp?ID=P...

Re: Backlit cedar box, LED help please.

The thing is that to “fade” LEDs you need to do it by PWM (pulse width modulation). I would suggest using BlinkM as they can work independently or be controlled by a Ardunio, one BlinkM per letter would work nicely. The good thing about these RGB LED thingys is that you can program a colour/fade seq...

Re: Electronic Enclosure

Yes it is wireless via Xbee, the only reason I used Xbee is because that is what I had lining around. I'm going to switch it over to WiFly (Wi-Fi) soon though. Xbee post Yep the fan keeps is cool as the air is pushed from one side to the other. And yes again, I've attached the SketchUp and Gcode fil...

Electronic Enclosure

I finally got around to making my own Electronic enclosure, It's just a “flat pack” with some added LED wave guides to channel the LED light. I did miss calculator by 10mm so I had to put my fan on the outside :( http://i34.photobucket.com/albums/d104/htpc_for_me/TEDA2732.jpg http://i34.photobucket....
