CNC PLANS

Hello

Awesome site!

I have some questions:

Q: How do you set it all up? - you've got a design in 3d, export it to a CAM program (i've gotten hold of Mastercam X3..). Translate it to g-code, and off you go..? Do you manually select/define the resolution of the part to match the drawing, or?

Q: How much did it cost you to build? - 2000-2500 seems like a lot when you look at how much the motors and so on cost!

Q: Do you have plans for a 5-axis build?

Q: What is the accuracy of your CNC?

Q: What is the limiting factor of the speed of the maschine? - I've got a Bosch POF1200AE (1200W router) that i may want to use. Is it the power of the router, processing power of the controller, the stepper motors or?

Happy new year, from Denmark!

Hi and thanks!

When I make my machines I do my parts in factory using gcode. We just look
the sketch (dimensions) and make gcode directly in cnc machine. If you want
make machine code of some 3d part then you must export dxf file (2d) to your CAM
program (easiest way) of the side you want work up.

I have no plans to build any 5 axes. This days I make a new cnc machine
version 3.
I think the version 3 will be one of the best I will make. When I assembly version 3
and if everything is OK then I can sell cnc router as a kit (only parts I make in a factory).
Version 3 image is here:


The price is no high if you make your machine in a real factory with a big industrial Cnc machines.
In Sweden one hour working on such machine is approximately 100 Eur. I pay for every part.
The accuracy of machine is 0,0025 mm.

The limit factor could be every part on your complete machine. Most important is precision of all parts
then a good driver like a gecko g540 then stepper motors with low inductance and so on.

I am no expert in any question about Cnc machines but an hobbyist. I have a feeling and good contacts.

Hello,

I am Pierre MARAQUIN, a student in engineering school by apprenticeship in mechanical sector.

I have to realize a work placement abroad during 9 weeks between June and September, 2010. Could you help me to find my work placement, because I am interested by Sweden. You say that you know many persons thus I allows me to ask you it.


Thank you very much.

Thanks a lot for the answers, Boris!

Which program did you draw the machine in? - i use solid works, and it gives some errors when i open your files.

I want to make something like yours, with the possibility of milling aluminium. YOu have a video on youtube of it, but it seems like it has a bit of trouble. How come? - is it not the right spindle (needing more torque), or is it a matter of bering rigid enough?

I found the Gecko Driver GS540, power supply and 4 Nema 387 ozin stepper motors for 600 USD. Do you need any more electronics? please see here for a wiring diagram of a 5axis machine:

Almost all the components on this picture can be bought from:

Like you, i'm just a hobbyist. I have zero experience right now with CNC, but i want to learn it. I want to make speaker cabinets, subwoofer enclosures and signs in wood, and perhaps some milling in soft aluminium. I hope this machine can do it.

PS:

Does the 2500 USD include the spindle also?

Hi, Boris, what do i need to do to see your link to version 3?, When i click it it says that im not authorised to download the attachment.
