yep , i have done it several times before and for the same purpose
0.3mm , but i used a lathe
very easy

make them legalize the invoice from the USA embassy in china .
i think it will cost 100 or 200USD but no one can dispute with that .

Join the revolution , we kicked the government out , and trying to build our country now.:bs:

oh and about usa and Europe thing , sorry to say i visited USA many times and the American people are...

anything easier ? :)

anyone can guide me to where to get/buy , api or whatever software component that can be used in C or VB to interpret gcode ?
thanks

how ?

yes i think it is stamped for part 2
for part 1 , i dont know how these holes are made
it can not be made on lathe
as i am looking to make few 1000s of them
so i am looking into mass production...

these 2 parts are very small about 8mm in length and about 4mm diameter . its a cone like shape

i will appreciate if anyone can any one tell me how are these parts made , machinery used ?
...

check the mach3 site, there are a PP for mastercam there.

actually there is
and it produce very nice results
its called 3dsom

thanks alexander , very nice work.
the schematic seems a bit confusing at the first glance, have to look further
also u said that you have a drive board and slave boards, which one is on the...

i am very impressed
thats great

thanks a lot alexander

very nice work adc_cnc
are you going to share the circuit and code ?
thanks

hello aarongough
i have followed the fabber and reprap projects since it was created.
in my opinon, till now i dont think it can sell with its current status.
its slow, unaccurate, no good...

ok , a lot of people may think that the z-axis will require less power motors, and this is not true, actually z-axis needs as strong motor as the rest, again according to my experiance, and i think...

vger
your not completly correct
the new drives today will simply allow you to put higher voltage (20x) and limit the current to safe one (2 or 3 amp)
so your motor wont melt or anything.

is there any kind of device for measuring torque for motor ?
digital maybe ??
any diy stuff i can make to measure it .

thanks

i have a varity of power supplies from 24v to 70volts. (1500watt)
so enought for anything
the driver i use is a commerical driver similar to one sold by the UK company motioncontrol or something...

anyone ?

hello
i have now some 8 wire stepper motors,
here are the specs
2.8amp 1.4ohm 3.9mh 34kg.cm (about 500oz)

it has a data sheet with the the curve below

from what i understand its...

i have read this thread from the start
i came from a chemical background ( i am a chemical enginner)
i had many test before on different kinds of polymers
most of these are not impact resistance....

can u also test its thermal properties ?
can it stand high temp
maybe we can cast aluminum in it ?

i wonder , why did that thread died away
are you all out of forumla`s ?

now , ok
i am a muslim and live in the middle east , i am 36
however my mother is british and i have been in the states many many times.
i jumped from page 9 to page 22 of this thread.
i will...

you are correct in every word, but offcourse 1000watt and 1500watt power suppliers are more expensive.
i can offer a price of 67$ for 50units 500watt 48volts PS. the voltage can offcourse be from 40...

our company has a dept which is specialized in switching power supplies only.
i wish i can have a us distrbuter that can buy in bulk and resell them again.
we really have great prices and i can...

ger21
the stepperworld driver use resistors to limit current, other drivers uses PWM or chopper to limit the current
i think thats the reason this is why the motors with stepperworld driver needs...

guys , guys
you only need 2/3 of the amp rated on the motors
example
3 motors 3amps each
total is 9amp, but in the real work you only need
a supply of 9x(2/3)=6amps
to be on the safe side lets...

my company uses switching powersupply a lot.
very nice size and very light weigh compared to the transformer type (3kg only).
they come in 48v 10amp, and 48v 20amp
i think the price is 180$ for...

i am not seeing the atmel code, or the hex file on this thread
did i miss it or its not an open source ?

thanks
