all different sizes colors different Wires got a bunch of stuff all ready
I been getting liner guides from work that have been thrown away
for what ever reason

this is a picture of the mill I got
I picked it up in fort worth Ind and took it to lansing in a
ranger 230 miles
the repair shop called and said that my back axel is fixed
and come on in and lets talk about it I got good news and Bad
I just had them put new brakes on [:{ but the truck has 125,00
on it and I was dooing donuts earler
only look with one eye

I got these at Kitts a local tool store

6 inch vice sides are ground square so that vice can be placen on its side
8 inch rotary chinese imitation Kitts said that if the handel is cranked
and cranked so that the table is rotated 760 dregees or more
eventually it will jam? any body hear of that?

50 volt DC motors

how about 3 of these for power supply
they are $4.95 24 volts 2 amps


http://www.goldmine-elec-products.com/prodinfo.asp?number=G14276&variation=&aitem=3&mitem=4

another choice
http://www.mpja.com/productview.asp?product=12418+PS
$39.95 24 volt 4.5 amp

I dont think you would be able to power one of those motors with 3 of them.

Take a look at the 10a 24v transformer or 2, maybe more from mpja

Jon

Is this right volts X Amps = Watts
first one 24X2=48 watts
last power supply 24 X 4.5 = 108 watts

28x14=292

Sidecar, do a lot of reading:)
Youll have to figure out the power requirements for those motors, how they work along with the drives and everything else, maybe start a thread for your own conversion.

Jon

36 volts 8 amps 100 bucks
http://www.bpbsurplus.com/items/item652.html

48 volt DC Voltage Adjustment 2 models 41-56 Volts and 20-26.4 Volts
$169.00
http://www.usdigital.com/products/ps320/
thinking of 41-56 volts

I suspect those Ametek motors are rated at 50 VDC at a maximum of 10 to 12 amps. So, at a minimum I would find a 48 VDC power supply that will supply 30 to 40 amps. These should be commom Telco power supplies. Or buy yourself a toroid, a bridge rectifier, and some Sprague electrolytics caps 47,000 mfd at 75 VDC from http://www.mouser.com The toroid are available on ebay for about 40 bucks...you'll need one that has two 37 VAC secondaries at 15 amps that you will need to parallel.

here is another power supply
24 volt at 8 amps 59.00 dollars

plan on running 2 motors on the +28 and other 2 on -28
what you think?

I ordered e2-250-125 today from us didital

hpoe i dont
dont make a misstake in the order

Tested out computer that will be used
Need to get 1/8 reamer and drill for it and some dowels too
May start drilling holes in the ends of the dc motors

Question could the dc motors be used on a wind mill
to charge battries then if a DC spindle drive is used?
I would be Plug it in the wall less
did you here about the guy that converted every thing in his house to
12 volts and got his electricty from the phone lines !!!!

50 volt Servo motor too big?

I have a Homier also, and a HF 33686 too. The Homier is a real bargain for the price, and a nice little machine. I dont know about using if for a retrofit, I am going to convert the big one to cnc.

Hi,
I too have the homier 1.5 hp mill/drill. I am interested in the cnc conversion but are there any other options for anit-backlash lead screws other than rolled ball bearing lead screws?

Yes. You can used ground screws is you have lots of money. You can use the original acme screws if you don't have much. The rolled ballscrews are a happy medium at a reasonable price.

Eric

Eric, How would you get anit-backlash out of the existing screw?

My nuts had an antibacklash mechanism built in. Kind of a split nut with a bolt. I am not saying it's ideal but it's an option. Most fellows who have tried it have had limited success.

Eric

ALaddie
here is a picture for yaa
its all in what you want and how much you want to spend
and were its going to set I have a guy at work thats building a
10 foot by 5 foot gantry
I have been reading and all I know
is if you buy a Geco you will only buy them once it can run
a big or small machine easy to use just need screw driver
but they cost more than a low power steppers set up
ie computer power supply powered 12 Volt

well its been a long time since last post
I have been reading as jFettio recomended
Oh yes have been working long hours at work as well
Its been a bit of a nerver racker buying all this stuff
I have collected lots of stuff
this is my second try at bulding a machine to cut stuff
well third
as I have all ready built the hobbie cnc foam cutter
it was easy and fun uses old computer power supply
drawer slides 5/16-24 threaded rod piece of angle iron with a tapped hole
no big deal under 300 bucks
so I left off trying to get some one to make my decisions about
what power supply to buy here is what I bought and its not stuff
http://www.mpja.com/category/Three_Output_Supplies/28V_15A,_DUAL_14V_3A_UNIPOWER_SUPPLY_15367_PS.asp

they fit Great in a old computer case
AS the BRITISH would say Bloddy Marulous just incredable
Its not a bad Idea to wear safty glasses I need glasses to see now
as one get older one dose/dosent get smarter
This is were we have crossed the line I.E. the danger factor of electricity

side pic blue wires 28v power left radio shac fuses
see gecos old computer heat sinks with fans on other side

got some 4 X6 tubing for fixture to drill encoder shaft hole
used 12 volt battery charger to power motor put grease on end of shaft
with the motor spinning drill will find true center also after 1/8 dowel
is put in place you can see if it spins true they say the human eye can only see
5 thousands of run out

encoder housing 4 needed Note encoder did not come with the screws
so small and you will need a tap too

it spinning true

side pic of fixture to drill encoder hole

clip comes with encoder to set the height of the light screen

encoder small

encoder light screen in place comes with allen wrench dont lose it

encoder reader installed

cover and wires hooked up fuzzie photo ?

I made the encoder housings
I want A easy Job
note had to mill slot for wire for got that and 1 time slot too small
took more time to figure out
the dimensions of the housing

what is that do we really need that when the red light is on is that good or bad
you can see the tops of the power supply
is this more stuff you really need
yes

pics of under side of mill drill Y axis before ball screw conversion

Y axis ball screw test fit
dont take out the paper tube well the tube all most fell aparrtt becouse IM SO SLOW
i know the pis is fussie
but you get on your back to take the pictures

here were the rubber hits the road

test fit of Y axis there were isues with the tapered dowel pins
as to possible turn then in to bolt holes so there is a 4 bolt pattern
like a 4 bolt main bearing on a big bolck engin\e
also did not have a taper dowel pin reamer i mean how much stuff do you need?

Y axis assemblie used vbx bearings roton ball screws 3/4 dia
I turned the ball screws on a lebond lathe with a carbide tool bit
turned the ball screw down to 15 mm for the vbx bearings then
cut it to 14 mm for threads lathe dident have metric so used 20 threads per inch
as the coarser the thread the deeper you have to go you will see more pic in X axis

yep tooo long got to grind off better not to short

Y axis done

no way more to go on
made on a cnc mill not a lathe
I made that
i want a easy job

note pis 1489 drive pin hole previous pic

yep take it appart for about the 4th time
note 1518 bolts from pic 1517 controls position of X axis ball screw
Y axis had to be removied to re adjust X axis ball screw
you will find out just get on with it

Goodyear were the rubber hits the road

oh yea I took it all apart then it kind of got rusty well
I had to read al lot of stuff
thats when i noticed
that the machineing of the table dovetails was not so good
but what do you expect from some thing from well I made that I want A easy job
X AND Y IS UNDER POWER
more pics to follow may be slow but ill get there

All right! Its great to see you off to a good start! That PS should have plenty of huevos and then some. Geckoes, your in biz, man! I dont know the slightest thing about servos, other than Geckoes are the way to drive them. The computer case looks nice, you did a nice job with the wires and the layout. When your done you can machine a custom front cover with your new CNC machine!
Wow! Your post hit right before mine so I'm editing out some of this post.
Good job, everything looks great, I like your design of the Y axis motor mount. Keep up the great pictures!
Whose ballscrews are those? How much were the ballnuts?

The above comments are the authors and do not represent the oppinions of CNCZone or its management.

It been alot of work
turning and threading the ball screws was a adventure
commimg up with the dezine was hard to
I.D. threading as well
Need a good lathe man for this Hey Its me I made that I want a easy job

X axis ball screw and mount note ball return
can not bee on top like picture

dident have things lined up right had to remove Yaxis ball screw again

got things lined up

turned one end size of stock Acme screw

ready to start assembly tapped holes all way through first
good pic of thread end of X axis ball screw

X axis ball nut pic right way around

extra pic of threaded end of ball screw

drive plate install have up to this point assembled/disamble Y axis 4 times
X twice 3 or 4 days in erall hot weather

bearing nut goes on cnc milled ID thread
found easer to use lathe turn by hand

bearing lock nut not tighten yet
used hex stock turned on lathe

here is photo
i used some 3/4 cold roll for a mock up of threaded end of the ball screw
so the bearing nuts and lock nuts all fit 14 mm X 20 threads per inch

1/2 inch shaft timing belt adapator 1/8 drive pin

timing gear installed 30 tooth L 3/4 wide

motor mounted to motor mount plate
used 4 10-32 socket head screws

ready to test

this is the rubber that also hits the road

3/4 roton ball screw and nut with over size balls
17 dollars a foot for ball screw
28 for nut and 10 dollars for over size balls

old mission control
using lap top now no pic
most of the stuff for the z axis done more pic comming

Hello, your conversion looks great!

Can you please provide more details regarding you oil/lube configuration for the ways?

I am beginning to see more examples of this but no one has provided any details regarding its design and operation.

Thanks... Norman

first picture i took

some times you have to stop and smell the roses
I will take what i can get

yes Turkeys

removed manual hand wheel
plate has slots in it so that i can get
clamps to grip inside of the head cavaty

pic of drive plate

here is were the pulliy goes

missed pic

checking for clearance

z drive parts

ball screw goes in here and pully mouns lower down

lets put this together
in she goes

nut

nut installed

on goes the pully

give it a spinn to see how it looks
great

picture under side of drive plate

test fit ok take it apart top view

side

bearings

ball nut

ball screw in balls came out i used a grinder to
cut tie wrap and ground some of the paper tube
got all the balls back in ???

can you see it a bad spot in the screw

i will be happy if it just goes up and down

added plate

x marks the spot

take some pic as there is a question weather this will work

I mean X marks the spot ?
on with the show good pics dont you think

it works by hand
dosent free wheel down
thought it would

side shot

lap top given to me
I fixed it
Question?
if you have a broken lap top
Can you still use the screen as a monitor

dont touch my geckos

5 volt supply
other side of case
you can see old compter heat sinks that are on the geckos
parallel break out board on the bottom
were it plugs in

over all view
if you notice the lap top is behind
the machine it is a big pain
it funny how you just all ways want more

Looks good,
You know that you can put probably all those pictures in one post right?

Jon

lap top given to me

Question?

Can you still use the screen as a monitor

It's sometimes possible with some laptops but it ain't easy.

You'll have to find out the pinout of your lcd/tft screen and even then it's a 50% chance you can make it work with videocard wich has a "Vesa Feature Connector".

It takes a lot of soldering but it has been done before.

Btw, I like your approach,

Jeroen

Possible.... sometimes. Worth the money? the answer is NO.
The controller for laptop lcds will cost twice what you can buy a 17" lcd for sometimes.

I know of a few laptop lcds which would be nice to have as desktop lcds, like my 15.4" 1680x1050 lcd in my laptop, but other than that, they typically arent that great other than physical size.
