Welding Up The Table!- Maracaibo, Venezuela
 

hello, greetings MechMate lovers. excellent forum not stop reading, I'm from Venezuela and empese and buying parts,

yesterday buy the rack and pinion Module 1.0 8 mtrs in total cost me 529 dollars in canada buy them in this store: http://www.motiontek.ca/index.html

next week I'll be buying the engine and driver: the engine is this and chose the driver:

NEMA34 640 oz-in Stepper Motor 4.5A (KL34H280-45-4A)
Gecko G203V Stepper Driver 80V, 7A

http://www.automationtechnologiesinc...ko-driver-g23v



please if you have some recommendations for me, I beg the help.

preferably paypal payments, currently HAVE A 1200 dollars to buy the driver and motor

my project with MechMate is create one that can use it with: rauter plasma cutter.

greetings to all the forum especially the forum Gerald_D excellent job creator friend, and I have time for here, did not have the money for expensive invercion is right now in my country, but I can and I started already.

thanks hope some comments that might help me at hello.

pardon my English use a translator

Felicidades por ese comienzo, me apunto a seguirte en tu construcción.

Como puedes ver yo tengo la mía under construction desde hace miles de años, a ver si le doy un empujon.

Supuestamente tu mesa es de 3x2 metros

Saludos.

Pa'lante maracucho :)

if you need help I'm in Curacao, next you

Hi hevert
Welcom and you will have a lot of fun building the MM

Regards

saludos
 

erga ahora es que hay de los nuestros por aqui, jajaja

isladelobos yo tambien tengo rato tratando pero sabras con es la cosa aqui en venezuela con los dolares jajaja, si quiero una grande
parrulho panita y tu tienes MM? que compraste por venezuela? en bolivares jajaja, me avisas si hay algo para comprarlo de una.
paulus ty

bueno yo ya empese a comprar partes ya me compre los rack y pinon que costaron como 570 dolares en canada, ahora voy por los motores y los Gecko G203V pero estoy esperando que paypal me permita comprar no he confirmado las tarjetas se tarda aveces. bueno muchachos saludos

hello, greetings, please'm buying today the engines, but I hesitate queiro help me to choose the engines. I can not buy me the 7.2 are very expensive for me. but I can buy these:

whom I recommend them? I buy them? I want to learn to pick my engines, but do not understand many things even though I read a lot in the forum, if someone gives me an instruction I would read all the to to understand for myself and to help others in the forum, greetings hope can help.

Helvert.

Motors & their mountings

I have the motionKing motors.

I have the more expensive motors but I would buy the motionking motors and build belt drives.

good, buy you steel this week to start working with my MM, future numbers? lol, I will try to be as accurate as possible to the original, I did some drawings that are perfect for construction because you can take action and everything. Google SketchUp is very good.

I have the files in Google SketchUp if somebody wants me know

looks good.

hello sir, I tell her as I go with my purchases:
I bought all this: PS-8n63, PMDX 122 34HS9801, rack and pinion, laser cuts mike, gecko drive 203V, Spindle 2.2, 3:1 gear XL, I can buy you more than I need?

hello, I need help, I can use UPN 240mm Beam profile for rails X?

If you are buying from Deitech, do get extra length of rack. You might have to discard 2~3inches of the ends. Even so, its still a bargain...

10 10 320
 

hello friend, do not speak of the rack, and buy 7.5 meters, I'm talking big steel rails October 10 320.
in my country it is difficult to find 10 10 320 steel. I found one but 3000mm * 240mm * 75mm, if that's okay? or is very heavy and big?

screws
 

hello, greetings where I can buy these screws

http://imageshack.com/scaled/medium/585/8hvm.jpg

Nothing wrong with 75x240x300mm. Some of us here like it big and heavy.

Is that for the W-wheel? Is it a screw with built in concentric bush? You can use the if you like but a simple screw works just fine.

hi ken, thanks for your answer, if I have the opportunity to put a single screw, but I want to be more Cadre, I would buy those screws, just not where to buy them? you can say that I find? I have searched a lot.

Is that for the W-wheel? yes

greetings, people MecheMate. my toys are arriving to start divercion lol


where you can find information on how to connect:

PMDX 122 + 34SH9801 + G203V + PS8N63R12

Please need help

MechMate Hello friends, I'm in my test control box, but I have a problem and my 34HS9801 8 wire motors: Amariya, blue, green, orange, red, white, black, brown. ok in the planes of the MM, connect (Red and Yellow Phase A + A-phase) (Black and Orange Phase B + Phase B-) ... Now what to do with the other 4 wires: Blue, White, Brown, and Green?

Help is well connected?

just to test that everything works

Looks like you need your resistors on the geckos and you have a look at your other 4 wires on the steppers, how are they to be wired? Bi-polar series, bi-polar parallel or unipolar, you will have to pair them properly, its the set up you used to help you choose the power supply. I haven't really looked at the other wiring.

hello tom: half coil

had an error with the black wire, and change it to white, it caught all good, but when you connect the parallel port, the plate 122 pmdx led all turned dull, turn it off and went back to fast on and lit a fire ship in the plate

and i do not know why I spend so conctado if everything was ok, the problem arose when connecting the cable from the parallel port,

has the parallel port cable original cable some different settings?

I probe the small connector db25 pin 20 and all had good continuity.

I could go there?

two images: 1 all working, and the other the ship burned.

Are you saying that your board burned up? that wouldn't be good. In the picture of posting #23 I see no resistors on the gecko drives, have you put the resistors on? Does the PMDX 122 have a 'test mode' you can run? If it does you will want to run it first before connecting to the computer. I have the PMDX 126 which does have a test mode set up. Find the wiring diagram for the steppers and wire them accordingly. http://www.mechmate.com/forums/showt...f+coil+winding 2nd or 3rd posting down. Good luck.

UNIPOLAR

[IMG]http://imageshack.com/a/img201/822/nhi.gif[/IMG]

if he seems the pmdx 122 is burned, if the resistance be installing the morning, pmdx 122 has test mode? I do not know friend, you know how? of 8 cables connected only have 4 in this image: a-a / / b-b, red and yellow .. white and orange

If you have 8 wires, pair them like the first image, if you have only 4 wires then they will likely be directly connected to the drivers.

Your manual for the board should have the information about test mode(s) if any available.

Page 6 of your manual shows an example set up, that's all I can recommend for the board to drivers connections, like I said, I do not have the 122. If all does not work, you may need a new board.

You will have to look at the geckos for the resistor values, the steppers help determine the amperage required to operate properly. Again I did not use geckos so you will have to find the information throughout the forum, in your manual, or on a support website. Sorry but I can not help you on this part.

Cutting
 

starting cuts for my MechMate, I hope to finish it quickly, I'll be putting pictures of my progress

I LTD50 LOTOS Plasma Cutter, very good

That's a nice clean cut. Keep up the good work.

The wiring diagram posted on November 30 is incorrect if the 4-wire diagram is used (assuming that the diagram for the 8-wire connection is correct).

I don't have a 34HS9801 motor, so I can't tell you which wires to connect. It is easy to find out how the motor is wired if you use a multimeter. Start by connecting one lead of the multimeter to the Red wire and the other lead to the yellow wire. If the diagram is correct, you should get a low resistance reading. If the diagram is not correct, then you will need to connect one lead of the multimeter to each of the other wires until you find a wire that gives a low resistance reading. When you find the correct wire, you have found the two wires to use for the "A" coil. The next step is to verify which other wires are part of the "A" coil. In the November 30 diagram, the Red, Yellow, Blue and Black wires are shown to be connected to the "A" coil. Connect your multimeter to the Red and the Black wires. Twist the leads from the Yellow and Blue wires together. You should get a low resistance reading, if the diagram is correct. Go through the same process for the "B" coil.

Assuming that the diagram is correct, you would connect the Red wire to the PHASE A terminal on the G203v, the Yellow wire to the PHASE /A terminal, the White wire to the PHASE B terminal and the Orange wire to the PHASE /B terminal. If the motor turns in the wrong direction, exchange the White wire and the Orange wire.

The 34HS9801 motor is rated at 4A. The correct resistor is about 60K 1/4-watt. Any standard resistor that is within 10% of 60K would work. Using less resistance lowers the maximum amps that the G203v will allow. Using more resistance will increase the maximum amps that the g203v will allow. BE CAREFUL, allowing too much current to flow with greatly increase the temperature of the motor and the G203v. Connect one end of the resistor to one Current Set terminal and the other end of the resistor to the other Current Set terminal.

The 34HS9801 motor is rated at 4.1mH inductance. That means that you can use a power supply that produces 64VDC maximum. I recommend a power supply that is 10% less, because of heat, but I don't have that motor so I cannot tell you how hot it will run at 64VDC. Many stepper motors are rated to run at 80-degrees Centigrade. I like to run motors at a maximum of 55-degress Centigrade so that I don't burn my fingers if I touch the motors.

Going back to the diagram. If the diagram is correct, you would put tape or some other insulation on the Blue wire, the Black wire, the Brown wire and the Green wire. Those wires will not be used. They must not touch anything.

To make wiring simple, I crimp an insulated ferrule on to the end of each wire and then I connect each wire to a terminal block.

I'm attaching a photo showing an OrientalMotor PK296-F4.5A motor connected to a terminal block.

thanks tom, mike connect: the connection of cables is 34HS9801 //A RED A-YELLOW// B WHITE B- ORANGE// and all well test and.

I'm using a font, PS-63NR12

help please
 

relived hello, good friends start again slowly, I'm making the holes that grip angle rail, tomorrow I hope to finish them, to assemble the table.

I also get my pmdx 122, that burned the last time because the power supply instead of giving 17v and 12v gave me the pdmx burn, and my repaired for free, just had to pay shipping from Venezuela.

now mount all the wiring again on my test box but can not get the motors to rotate, see photos here who can help me thanks and regards to this beautiful community XD.

WOW!!! The most impressive test box to date!

Do you mind sharing where you get your relay board? and its detail.

Hi Ken
 

Hi KenC thanks. Clearly I can

no installation diagram with 3-wire NPN and this kind of realy

if you buy it help me configure mine lol. because I aller turning head explode as installing and neutralize if reaches its limit.
can you give me a brief: Explanation? what function do the NPN and the resulting pin? pause the process? the driver turns off? shuts down the whole system?

The connection for NPN NC proxi swith is somewhere in this forum... I don't keep track of the info since I am not in any hurry to install mine... :p

Its here, I am using Seans diagram that works perfectly. Have a look here....

http://mechmate.com/forums/showthrea...0&postcount=71

Haven't seen that diagram in a while. One small error on that ... It's really only 12vdc and blue line is ground not -12vdc....which would be a 24vdc differential. Still works perfectly after 7 years on number 28

Today progress
 

Today progress
I hope to see it up tomorrow XD
