Hi. For this particular CNC I used a cheap chinese board with parallel port from ebay. It was about 50$ with integrated drivers. But I would recommend to use a better controller.
For my next CNC I have made a DIY board (http://www.planet-cnc.com/inde.... This is a breakoutboard with USB support. It will also require a driver for each stepper.
For another low cost CNC I have used a GRBL type of controller. This is just an arduino uno with a shield on top. On the shield there are a couple of drivers to run the steppers. The arduino is a cheap solution and also gives USB support instead of the outdated parallel port.

So for a low cost machine like this I would recommend an arduino with shield keeping the cost of the machine down. (http://blog.protoneer.co.nz/ar...

What controller did you use?

Hi. Thank's!
I used a small PCB milling bit found on ebay for the cut on the video. For this size machine I would recommend a dremel size spindle, like the one I use. A bigger spindle = heavier gantry which is not preferable. But I have not tried with a bigger spindle, simply because it wasn't necessary for the materials this machine was built to mill...

16mm MDF
12 1½" U-bolts (see picture)
1½m M8 threaded rod
M8x16 bolts
M8 spacers
M6x50 bolts

The BOM, pictures and instructions is a work in progress!
The machine was designed and made for about two years ago, and I did not make a BOM back then.

Results look great! i'm build one like it, wish i had found this one first! What bit is that and where did you get it? I have 3 dremils but i also have a small Sears Router and a Rotozip any recommendation on which to use on a machine this size? Do you think a machine like this can support a small router?
Thanks for info Choc

NEMA23 motors??

nic6911 on Jan 21, 2013 said:

Yes it is nema23 motors. The BOM is a work in progress, but all the things are the same as used for the other cheap cnc i have uploaded. And the BOM for that is more complete at the moment. The only difference is the size of the machine.

Nice little machine :-) how is the dremel working for you? Because the mill we have with a dremel has a wobble because dremels have their spindel placed in rubber, so it can wobble. Making it unable to use it for PCB milling.

nic6911 on Jan 11, 2013 said:

I haven't done PCB milling, so I don't know. But a dremel may not be the best choice for a precision task like PCB milling. On the machine I use now I have a Kress 800FME which only has an outrun off 0.079mm 40mm from the collet.

This machine reminds me very much of a swedish made machine called the "lillasyster". Nice work on the design.

nic6911 on Jan 11, 2013 said:

Hi, just googled that machine, and yes they look almost the same! My machine is not a derivative though, Have never seen that machine before now, but I must admit that mine looks quite a bit like it.

What software do you use to drive your CNCs?

nic6911 on Jan 11, 2013 said:

EMC2 or MACH3

nic6911 on Jan 11, 2013 said:

EMC2 for linux or Mach3 for windows. CAM software i use is Lazycam.
