hi again,
hope you did'nt get me wrong in my last post...?

since 10 minutes ago i'm ready to go... i got my steppers to work -all 3 of them :-)
woohoo

sound like a good plan an a lot of work...

i could spare a few hours today to tried it out and it did not work, which is not really surprising for me since i am not really new to linux but i have to learn a lot of things  so i probably did something wrong.
i could offer you to document everything in a latex file hoping that in the end it will work for me and there will be a more user friendly installation guide ( no offence, but if you dont know anything about linux its pretty much chineese).

Im gonna start over and post the problems

i would love to contribute but my skills arent anywhere in your range so i guess this is my way

hi dewy,

First of all : Respect for what you have accomplished so far!!! really cool project.
i'v stumblues upon today so i dont really get all the components but i guess the basic is clear.
iv been working on my CNC since last summer after buying an arduino i thought that should be possible, but i did not know anything about anything! So after a lot of reading about basic electronics and steppers and (.. you know what i mean) i finally got the mechanics together and now its time to implement the controlling part. i will be using an arduino UNO for now  but probally it will be a MEGA or DUE to have enough pins and 3 A4988 shields from Pololu. ( theese basterts took me a long time to figure out that they need to be cooled, but they work fine now)
At first i wanted to parse a dxf and calculate it into the correspondning XYZ coordinates and use an adapted version of the stepper library.
the problem is i would have to implement everything myself. Lines at any angle is eays but wehn it goes to cicles and splines i will have to spend a lot of time to get an accepting code.
i took a look at LinuxEMC some time ago, but the problem was i had no idea how to get the connection to the arduino

So here you are with your project!! Awsome :-) !!!  i will try it out as soon as i can and will tell you how it works for me!!

thanks allready

keep on coding

jeff

hi,

Ich bin auch dabei mir ne CNC Maschiene zu basteld und hänge bei genau den gleichen Fragen.
Das grbl shield ist das was meinen Anforderungen ( hauptsächlich I>2A und nicht zu teuer) am nächsten kommt.
Meine Frage wäre ob ich das grbl shield auch ohne den Gcode interpreter ansteuern kann, also dass ich die bitfolge vom arduino schicke und das shield einfach als Treiber nutze.

die haben einen Monat Lieferzeit....
5  Using Arduino / Motors, Mechanics, and Power / writing my own software for cnc controlling??? on: September 21, 2012, 03:03:37 am
hi everybody,

a few month ago i decided to build my own cnc machine. actually i started as a complete newby but i got some programming experience.
i found a conection for matlab, so for now im planning on using this live connection to matlab which simplifies the hardware conections.

i want to draw autocad files( since i got experience in that aswell) save theese files to *.dxf ; get them interpretated in matlab and calculate the coordinates for the 3 steppers to go.
 
in my mind it does seem realizable but i would like to heart your opinions. am i reinventing the wheel? the first goal is to make it as cheap as possible and to learn as much as i can by doing it.

for more info just ask
