Easy to build CNC Mill Stepper Motor and Driver circuits

Step 5 Let's Watch it on TV

I just like watching a video better than doing a bunch of reading. Hope this is helpfull. Good luck with your projects. If the movie doesn't show past this link into your browser.

I managed to build this one , the motors are turning properly ... I still have some problems with "ignition" ... the serial port sometimes doesn't turn the driver on properly.

I was wondering how many Amps could I draw from this circuit powered by how many volts ?

Thanks!

[ziggalo]

does anyone have a video of this thing running? like actually making something? I'm just really frustrated in making this work, and I need a little inspiration. Thanks

[woodspinner]

sorry, I dont have mine that far yet, what problems are you having?

[ziggalo]

I got my PCB made at home, then halfway through soldering components in....I realize it's backwards. So it's back to square one with PCB manufacturing. *sigh. and now the PCB isn't working. Very frustrating project, but I can't wait to see one run. Good luck everyone

[woodspinner]

That must have been very frustrating. I have mine running x and y from a solderless breadboard until I can build a z axis so I can route the pcb. Hopefully that will happen soon.

[ziggalo]

I haven't tried breadboarding it. I just put in a hell of a lot of faith in the circuit design. crossing my fingers.

[woodspinner]

I felt breadboarding would give me a better understanding of the circuit and how it works. I wish I had the ability to just make the pcb but I've never done that before. I'm waiting until I get the z axis built so I can route it, but money problems are making me wait.

[ziggalo]

I finally have all my components in. time to test. however, i don't know which IC goes where. On the PCB layout, which socket is for the up/down counter and which is for the decoder?

[ziggalo]

still a little unclear. You said you breadboarded it. According to that, which IC goes on the column of sockets that are closest to the parallel port?

Explain that!!!!!!!!!!, becouse someone is provideing wrong information, or Tom McWire, that create this tutorial, or you. Becouse if you see this image, you can see that the pin 1 of the cd4028 goes to the Gate pin of the Mosfet. and in your image that cant be done. So please, justified why you said the decoder (CD4028) goes closest to the parallel port. Do you get your cnc working? can you provide images or videos of it?

[ziggalo]

Yeah, I think chony is right. I looked over the board of appeals again and noticed a four digit label for each of the IC's, and a quick reference of the parts list, I believe that the up down counter is the IC that goes closest to the parallel port.

[rohilla.hitesh]

Could I get the part list??

[woodspinner]

parts list is above, the rtf file

[edgarx29]

porfavor ayuda
yo desarrolle el el circuito lo conecto a la pc y use kcam y no no funciona bien lo configure en una forma que desia unos de los comentarios y de todas manera no trabaja bien

yo lo que les pido es que me muestren con imagenes cual es la configuracion real del puertos en KCAM es que lo estoy haciendo para un proyecto de nota semestral de la universidad y lo necesito lo mas rapido posible porque se termina el semestre en inicios de julio

[jorgeneo560]

que es lo q te esta saliendo mal?, a lo mejor estas usando motores bipolares paso a paso, cuando compras un motor paso a paso generalmente te lo ofrecen como unipolar o bipolares, que estudias?

[sxyuklad]

where should the 3 wires (direction, step and enable) from x axis driver be connected to the parallel port (what pins and data? and where they go from y and z axis? and are all these 3 wires all from one driver that must be connected to lpt? and what mode for lpt should be selected for it work (ECP, bi-directional or any other)? please explain as soon as possible, im stuck waiting for your answer and I can only go ahead when I am answered to all my questions for which I thank you so much in advance. And would the same driver work with mach2 or mach3?

[sxyuklad]

and if I am hooking up 24v 1A/phase and 30v 0.75A/phase motors what should be the volts, ampere and watts of power supply and do I need to change any component values?

[sxyuklad]

can i use 10n60l instead of 12n10l? please clearify. i cannot find them, 10n60l is what i can find. or tell me any alternative like power transistor like 2n3055 would work?

[sxyuklad]

and if i have 7.5 step motors, what should be the settings for kcam or they are same as you illustrated for every motor?

[sxyuklad]

I am building this... What voltage and ampere should the power supply be? Can it run 24-30v and 1A/phase motors?Where in the circuit the yellow, orange, brown and black wires from motor should go and what should be the sequence? Can I use power transister if I can't find fets? Because I can't find 12N10, what can i use instead, please help. I can't find the bulbs as well, what resistance they have and what is the wattage for them? can i use 5watt or 10 watt resistor instead and what value of them? Please help soon. I am dying to trying it out. Thanks.

[bobsmith760]

When I click the yellow arrows the green number doesn't go up and my motors don't move. Any suggestions?

[parasite66666]

I´d guess you didn´t set up your pin map in kcam yet.
You need to set all the pins you´re using before the joging will work.

[bobsmith760]

 Yep that was it, thanks.
Also to anyone else building this circuit, you can use a 4029ic counter instead. Just connect pin 9 to + power.

[biffit]

What exactly are the servos that you are using?.

[the_mad_man]

he's not, he's using stepper motors

[thatonekid]

bipolar stepping motors

[maclinfuehr]

 bipolar have more than 4 wirse and unipolar have 4

[caustic4]

I believe you're mistaken. Bipolar stepper motors have 4 wires and unipolar stepper motors typically have between 5 and 8 wires. This is a 5 wire unipolar stepper motor.

[mackd7777]

Its a unipolar motor beacuse it have 6 poles.

[065]

Hi I'm currently trying to construct your machine but I'm having trouble understanding  how your machine works with out and limit switches?

[buddace]

Which Lamp Type (voltage and power) are You using ?

[amitsharma2904]

 you can use a dc bulb of 9v 2-4watt.
thank you

[Asmodeo]

Ecxuse me for the question, but....which transistors (part number) and clamping diodes (D1 to D4) are You using ? I have etched the board, an I'll buy the materials this saturday. It'll be a test for some Stepper motors I have lying around. If they succeed, well....perhaps another CNC router will be born! Thanks a lot

[Javidana]

IS it possible to a make 4 axis verison of this circuit? Great work anyways thanks alot, gonna visit the electronic shop on monday to buy the parts. luckily I have a good friend who'll help me out with soldering... Thanks again

[mikorf]

Bravo Great idea .
Can i use Arduino board instead because i don't know much on how to make pcb and electronics?
(http://www.arduino.cc if you need more information)
thanks

[mikorf]

thanks for your help. After finishing my present project i will start making this one with Arduino Controller.

[Tom McWire]

Absolutely you can use an Arduino. That's a great idea. I'm looking for ways to make the motor drive easier. So many people get held up on the electronics. Let us know how it works out for you. Tom

[BikiniMadness]

Tom, I'm one of those 'held up on the electronics' type of people :). So do I need 3 x Arduino? Also, am I correct in that once I design something in a CAD application, I can feed that to the Arduino application to create code to drive the CNC? Thanks!
