OK I ordered the 48V Power supply can someone point me to where to get steppers 260-300oz for the three axis I need them for specifically with the thru shaft design to add adjustment knobs for ajsting the axis whe the steppers are off

[JoeDawg]

I have Keling KL23H276-30-8B's which can be found at

http://www.kelinginc.net/NEMA23Motor.html

These were recommended by several people and Keling is a very reputable supplier

[gunlocators]

Well got most of what I need or atleast half

Setup Taig Mill Today have to find machinist square tommorrow to square bed to spindel. I installed Keling 282oz Steppers Received 48V 12A Switching Power Supply and My Gecko 540 Controller

List to go
Refurb one of my spare PC's
Sherline Rotary Table with Servo and Tail Stock
48" Cue Fixture
and Software to run this PUP

Make sure you get the Sherline rotary with a stepper motor, not a servo.

Thank You Sir Will Do indeed. Now I am debatin if I am going to mount directly to the ugly 35 yr old bench its on it solid wood with a formica top or if I should use some birch plywood

[fretsman]

Looking good, but if the birch plywood won't be covered with anything, I'd stick with the laminate top for easy cleaning -

Here are some helpfull tips for setting up the g540.
When setting up the pc. make sure the printer port is in EPP mode in BIOS (CMOS)
If you are not setting up a external E stop switch, then you will probably need to take a jumper wire from pin 10 (on the side of the g540 and jumper this to the ground pin on the g540. If you experiance troubles when milling (I could jog and everything looked good but when I cut a g-code it was way off) you may have to setup mach 3 in Sherline 1/2 pulsing mode.
make sure you setup the charge pump pin in mach3 (pin 16)
Good luck and a am awaiting your results because I spent almost a week trying to figure this out!

Please post rapid speeds as soon as you get setup... and remember, you can tell them to fast as you want and they won't know that they cant, the only way (that i know of) to know their actual max is the method i described in my first post. I would say start at 20 ipm (or about 500mm/m) and work your way up at either 5ipm of 100mm/m intervals...

A few other things:
-You can use machine coordinates and soft limits to eliminate the chance of running into your fixtures,just watch the mach 3 tutorial video on coordinates

http://www.machsupport.com/videos/

-In a lot of situations it is probably going to much simpler to treat your rotary axis as if it were linear one. You would just say I want this to be 1 inch tall and go half way around the shaft. Your drawing would have the same length dimension (up/down the shaft) and your width would be (pi)(shaft dia.)(.50). You could even make a wrap around design so long as the edges of your drawing (not top/bottom, the other two) match up. Now if you had a tall design you would have to compensate for the narrowing diameter of the shaft. Perhaps you could do something with the formula option in Mach3? Been meaning to look into that feature..... The other option would be generating g-code for a rotary axis, not sure how fun that is...

Of course I assuming your into butt (the lower half of the cue for anyone who doesn't know) designs. Linear tapers should be easy and curvilinear ones (if any of the shaft tapers are??) aren't very complicated, you can just use a set of 3 points to define the curve on a freeware CAD program, save as .dfx and import into Mach 3. Just let me know and I'd be happy to elaborate on any of these processes.

Where can I find a good push button kill switch for this pup

Kind of looks like our products.

One last question for now. Any one direct a good place to get a lockable wall mount project box to place the controller power supply and emergency stop button in perfer aluminum or steel as long as its large egnough to house everything

[TOTALLYRC]

I several nice used cabinets.
PM me if you are interested. I will be putting them up for sale next month to the general public but if I can help now I will.
Mike

[gunlocators]

I am very interested please post prices and pics

[TOTALLYRC]

I am very interested please post prices and pics

Pictures tomorrow.
I got attacked by some unscheduled overtime (nuts)and I don't have the pictures with me.

[TOTALLYRC]

Dear Gunlocators.

I was attacked by even more unscheduled overtime so I appoligize for the delay in posting pics.(nuts)







It is 20"tall by 16" wide and is 10" deep plus the door which is another 1" or so.

I would like $50 plus shipping for this one. I have a couple more that are in better condition but they are buried under my pile of stuff. I am finishing up my retro fit and will be putting more stuff on ebay in the next month or so.

The good thing about the overtime is I can buy more stuff for the shop:banana:

Here is how my enclosure box is turning out for my Gecko 540, Keling PS, Keling E-Stop and then other goodies.

This is for my Taig and so far from testing, it flys! My resistors come in today, but don't know if I will have time as I need to study for exams.






I got plenty of room The first things to do is cut out the panel slots, which I will do in a few days.

Well got a little further in the project decided to use a old breaker box with some vent holes for ps and controller. Also have a pc with mach 3 and optimized now i just need to learn to properly wire the steppers to the right pin config for the cables and to properly config the power supply ect to the gecko 540. Anyone wanna lend a hand LOL

Anyhow here my most recent pic

[Fixittt]

Dont be afraid of it, it is very straight forward. What I did was wired up my cables to the ends all the same. then I wrote on a piece of paper, what color was a a# b and b# seeing as my cables did not match the colors of wires on my steppers.
Then I looked up my steppers on the internet and found what colors were what. Wrote it down on paper that red went to orange black to yellow ect. I used wire nuts to make the connections. To make sure it all went well, then went back and soldered and heat shrinked them one at a time
