first result:
If gears are metric: To translate metric module numbers into US nomenclature, use the following equation: m = D/N=1/P where m is...
Very good advice.
I don't know about the rest of the world, but in the Netherlands your fire insurance is not valid if you leave within an hour after finishing welding.
I'm doing something like this: http://jwstolk.xs4all.nl/i/lineair_bearing.png
red = fixed frame ( http://jwstolk.xs4all.nl/i/cnc_2006_9_10a.jpg )
green = moving table
yellow = rail, 30 mm OD...
better yet: add a small pin to the placement head. after picking and placing one component, go back to the reel, insert the pin into the reel, and pull it through one component using the placement...
very interesting thread :-)
I just had a thought: the feeders seem to be a costly and difficult part, but since we seem to be aiming at a speed that's near or just above hand placement, you could...

The original idea was to cut hard modeling foam, but it's slowly shifting to include MDF and aluminium as well :-). I don't think the...
This project has been going on for a long time, but I just dismantled the Lego prototype a few month ago, since I finally have started on building the real thing (tm).
It will be about 5 times...
Thank you. :-) this project has been going on for a long time, but I just dismantled the Lego prototype a few weeks ago, since I finally have started on building the real thing (tm).
It will about...
But you won't know which one is better until you found a use for it, and then you only have one left anyway :-)
That's what i did first. same result, just a reload and another 20 sec :-)
same with just the domain name. no links in the page info, lot of junk in the page source.
Maybe something with cookies or...
Is anyone getting past the "wait 20 seconds" message on www.elecdesign.com?
In my FireFox it just reloads each 20 seconds :-(
If you add "s." between "group" and "yahoo" you will find it has nothing to do with transformers at all :-)
instead of removing a couple of windings, you can add some (in the opposite direction).
connect the original and the added secondary windings in series and measure the voltage. if it is higher...
if it's a switching power supply, can't you adjust it to 40V output ?
is the 52 V DC or AC ?
i think that counts as "Finished 1 cnc machine" :-)
I only used the demo version a couple of times, but it was very easy to get used to. Just make sure you switch between inch/mm before loading any models or tools. (I often ended up with a 50mm 3D...
I agree completely, but I was taking about lasers. You can do a lot of damage to your eyes with a laser beam that would barely warm up your fingers. Light reflected from whatever you are cutting (or...
Thanks !
I'm to busy to read all the cnczone forums, I actually noticed this in my server logs...
I like the other two Lego cnc's. I must admit, I cheated a bit, I used stepper motors and brass M3 thread...
i have registerd for ICQ and we spend some time testing/debugging.
the non-working led's have been traced to a broken 4027 chip and the 4000's not being
able to drive the LED's directly. so things...
Ty connecting the "step" wire to +12V using a 10k (or similar) resistor, and then use a wire to
conenct it to 0V (at the same time) to generate the step pulses.
do any of the LED's light up ?
...
every time the "step"wire changes from 0V to 12V it will do a single step.
hmm, really odd, pin 3 and 13 are indeed marked as "step", but the connections are
not labelled in the chip, so i don't know what they do.
just a few observations:
-you will need motors with a...
The Netherlands:
about 1.5 Euro / L = 7.05 US$ / gallon
I'm glad my 3D cnc will run on electricity ;)
and I have one of these instead of a car:
http://www.ice.hpv.co.uk/trikes_micro.htm
I'm very impressed. it looks great, and i hope it runs well.
was the exhasust bending very difficult ?
Those gears might not be build for running 24-7...
From my own experience, cnc, especially 3D finishing, can take ages.. :D
jaap.
After looking at the (European) prices of steel square tubing, I've decided to build my CNC
frame from 50x50x4 steel U-beams. :D
Since my welding is about the level of "it looks ugly, but sticks...
Just a warning:
I wouldn't worry about my fingers. (i have plenty of those) I would enclose the whole thing
in an non-see-through box only to protect my eyes. Even of you don't cut (very...
