Let's Make Robots!

New Arduino Mega CNC machine......(UPDATED)

Cutts soft materials, wood, plastic etc.

My new machine, the other one was a prototype, now this one will use all the electronics....

 

Made with MDF, bigger than the prototype......

Almost done...

Can i use a DC Brushed motor with controller instead of stepper motor to move the tool along X, Y and Z  axis?

Here is the link to the motor i am thinking about

can this firmware work with the 2 pin unipolar circuit as provided on the arduino website?

can u upload a schemetic for connecting driver with arduino....plllzzzzz sir ... and the software u used to control dir and step reply as soon as possible...thanku

the tool i am using in the makita laminate trimmer.............. only bad thing is that it does not have speed control... :-(

i am learning cam software now and also searching for ways to rise my stepper speeds.......(lead screws, voltage, etc....) 

 

maybe gonna buy bigger steppers and a new power source to make THE BIG MACHINE..... in order to make bigger works......

 

I NEED SPEEEEEEED!!!!

engraving a picture takes years............................... but is so cool......... 

... is definitively the way to go, at higher voltages you will be able to get more speed out of the motors you already have.

But to do that you will need to change the drivers you have, with ones that implement current limiting and of course the power source for the motors. 

my gift to lmr........ too late...

Very nice!

The Makita must be worth the money isn't it? I might have to get one of those in a future when I'll probaly build a larger machine..

I'm able to go with 300 mm/min with the Dremel with a 3mm end mill at 1mm depth in laminate wood, you should have no problem going faster in MDF.

 

 

i am now learning to use cambam, and thinking of adding more speed to my machine.... tested it to 244 mm/min ......

Almost done.....

 

My machine now has a better cutting tool, Makita 3/4 HP laminate trimmer, also more options for the bits....

The control box has all inside, Arduino Mega, stepper drivers, atx power supply................ 

Made some cable holders to make a cleaner installation....

 It works really good..................

 

So happy with the result.... 

 

atx power for my cnc machine....................... more pics soon...
