Microstepping Bipolar Stepper Motor Driver
This ATmega48 based project involves implementing a low-cost, high-performance bipolar stepper motor driver. The driver is designed for retrofitting a piece of equipment for CNC operation with inexpensive interpreter programs. For example this board was used to control a milling machine.

Question: If possible to replace atmega48 for atmega88 ?
any change is necessary in asm code ?
thank;s

Hi Antonio,
replacing the microcontroller is always possible but with required changes in the code.

its possible to give the PCB file ?
thanks in advanced

Aladin, try downloading the project, and check there for those files.

hello Florin,
thanks for response i have downloaded two times the download files to be sure that those files “the PCB Design files” are not included .
thank you

Hi Florin,
Thanks for the contribution, in the absence of the PCB drawing, can you please take a close up photo of the front and the rear of the PCB so one could use that to draw the PCB Schem.?
thanks

Hi Cy, I’m not the author, the only files available are those in the links. Maybe you could try contacting the author, look for some contact info inside the files.

Thanks Florin for the quick response,
I will try to contact the author and see if I could purchase the PCB sketch from him.
Meanwhile would you know if this board could also be used for Unipolar Steppers too?
Are the IC’s used still the best options available or there are better choices like the Toshiba one etc.?
My specific application would be like like creating an X,Y cnc that could print huge pics like 3×4 meters in 256 colors. using a fine resolution about half a millimeter per pixel hence the file that contains the pixels will be huge like imagining an excel sheet of 48 Million cells(6000 columns x 8000rows)!
Is there a Micro controller that could store that many instruction or could ram memory be added to the board or the only option would be for the board to be permanently interfaced with a PC?
thanks for your help again.

I would suggest you start your work from this project http://www.youritronics.com/3in1-stepper-motor-controller/
this project was submitted by morgoth a youritronics hobbyist. He supplied source files and pcb files. The motors are controlled from the pc.

Hi,Florin
I’m Ame.
I clicked [Download Project] – [View Project PDF] it was shown me the things that not relate about code and circuit(it ‘s been sent to this website [http://www.circuitcellar.com/index.html]).
Would u mind checking it ?
Thanks in advance.

Hi,
I’ve checked the links and they link exactly to this project
CircuitCellar is just the website that holds the project.
