Design, development and construction of an electronic controller for a CNC machine. The controller controls up to 3 stepper motors (up to 3 axes), has home and limit switches, and is optically isolated from the computer.
Computer Aided Design (CAD) Model of the Circuit
Printed Circuit Board (PCB)
Technical Specifications
- Supports 3 axis in step direction control
- Supports unipolar stepper motors
- Can work in either full-steps or half-steps for higher precision
- Connects to the computer using the parallel port (LPT)
- Completeoptical isolation from the computer – protects the computer from possible faults.
- Home and limit switches support for the 3 axes.
- Header access to every free LPT input\output (can be used to enhance the CNC control by adding vacuum cleaner, lubricant
- Absolute maximal electrical specifications: 60 volts, 30 ampere, 90 watts (with proper heat-sink).
- Seperate control for each motor!
- Maximum of 35,000 steps per second for each axis
- Heat-sink ready
- Actively ventilated package (fan)
- Firmware upgradable
- Supports 5,6,8 wired motors
- Supported by Linux CNC (EMC2), Mach3, Kcam
CNC Controller Case
- 3 “one way” connectors for easily connecting the stepper motors while preventing mistakes
- DB-9 (“serial”) connector for limit-switches input.
- Emergency Stop Button (the red button in the corner) that completely shuts down the electricity. The button is lit (using a bright led) while the machine is ON.
- Well ventilated case using a 60mm brushless fan.
- DC (12v) connector
- General bench-top power supply connectors for the motor’s electricity.

Great work, i have built the one but stuck in torque and inertia. I think my circuit is not supporting to much i have used unipolar drive at the end powered by mosfets but is full step excited i think half step will make much better sinusoid and reduce humm.It is very helpful if u send me the circuit.
Hi there,
I love the design you chose. I was wondering if I could get an electronic copy of the component list, PCB layout and circuit board diagram. I’d love to build this.
P.S- An excelent work.
Un Saludo…
Would you please send me circuit board diagram, electronic components,etc to make 3 axis stepper motor controller
hey , when you publish the pcb ?!?!?!?
i want to make a driver circut of a cd drive spindle stepper motor. It is a
3 phase stepper.
Please send me a circut diagram of the driver circut.
Thank you.
Wow This Look Excellent…. Could you please email me what ever you have…circuit diagram … pc board lay out …docs…
I want to build one!!!!
hi, i am also interested to get some detailed information
of this cnc project. would you please contact me?
best regards, markus
Hi, Please can you send me a electronic circuit of this board??
Many Thanks

I am looking to do a CNC router table and I would LOVE to have the schematic and cut sheet for this to control my motors. Could you PLEASE send it to me!
Could u please can you send me a electronic circuit of this board of the bipolar motors. It looks vary well done
hello,thank you for sharing all this wonderfull stuff,I love it.
and I`d like to put toguether one control like this myself, can you tall me were can one find the especifications to put it together. I will really apreciate it. thanks.
Hy!
Please send me the circuit diagram of your stepper motor driver.
Thanks

That CNC controller of you seems to be very powerfull, how can i get the documentation and schematic diagram.
I live in Venezuela.

Hi
Nice work…impressed. Is there a way to get circuit diagram or can I order a board from you? Thanks

Hi,
I am also interested in buying the controller. I am in South Africa. Can you please give me information on where I can buy this controller?

Hi,
what are the SMD components on the bottom layer?
Thanks,
Daniele
how can i get full documentation and schematic diagram.
I am located in Serbia.
Could you send the schematics for the controller?
Is it for sale? or can I get it?
Nice pictures, but what about the schematic??
Hi, why your motor controller didn’t supports 4 wired motors?
What is the minimum impedance supported?
Thanks,
King regards,
Daniele.
One other thought, this is a unipolar controller, can you also do it for a bipolar motor, I can produce both boards?

Hi, I want to know where can I bu this controler,
Thank you.
ninguem te garante k placa funcione
a mecanica para mim e fácil
Please send me the circuit diagram of your stepper motor driver. I liked it very much. Great work!
Your CNC controller appears to be great. Will you be suppling it complete, as a kit, PCB and programmed chips?
Can you display prices and options on your web site asap please. Please include postage for Europe too.
Regards
Andy
Interested in 3 axis controller, how do I go about it to purchase. I am located in India. Thank you.
