Hi great project
I also want to build it but i cant get the driver mentioned imported, so can u suggest me any opensource or free driver circuit. I also want to know how to interface it with ,its very confusing. Can u help me and tell some good read regarding interface part, i tottaly understand the hardware part of it.June 2, 2010 at 6:45 pm #3636June 3, 2010 at 10:04 am #3637
i found some supported hardware from emc site. Please suggest one of them from diy section.
And how to interface with board ? what software to install how to configure them. I will start work when all parts are in my reachJune 3, 2010 at 2:19 pm #3638
Of the driver boards listed on your link (under Step & Direction Drives), I know that Xylotex and Gecko are commonly used by hobbyists, but I can’t say from personal experience whether they’re suitable for the DIYLILCNC.June 3, 2010 at 2:30 pm #3639
Further, if you’re interested in open source control, there appear to be a couple boards under the heading “DIY hardware known to work with emc” near the bottom of the page. They don’t appear to be quite as robust as the commercial options – our hobbyCNC kit, for example, features a capacitor the size of a soda can (something I don’t see in the DIY kits). Try one out and let us know what you think!June 5, 2010 at 2:04 am #3640June 21, 2010 at 3:39 pm #3641
Seems like this topic warrants a little clarification of terms.
When we talk about the driver, we’re talking about a power transformer (and other circuitry) that serves high-voltage, high-current electricity to the CNC’s stepper motors.
The controller, on the other hand, is a computer (either a traditional desktop or a microcontroller or both) that sends commands to the driver, which in turn moves the motors.
Our controller is a version of Linux made specifically for machine control, called EMC2. There are several other controller software packages out there, like Mach3, as well as different controller-hardware setups like Grbl.August 16, 2010 at 5:04 am #3642
I have decided to get hobby cnc kit.What does it consist ? I dont need motor and they dont provide transformer. So do they provide other electronics to complete power supply
I am from india so what would be shipping charges like ?August 16, 2010 at 5:36 pm #3643
@karandex, I’m not sure what the shipping charges would be. I would recommend contacting Dave Rigotti at HobbyCNC to discuss those details.
The HobbyCNC kit comes unassembled with the electronic components needed except for the transformer and case. We link to a transformer supplier in our documentation (in the downloads page), but it may be easier for you to find one locally.
You will need to solder the electronics together, so a good soldering station is important.
There is another site that sells the kits already assembled, in cases with transformers. Of course this adds to the expense, but it may be worth it in your case.October 4, 2010 at 8:27 am #3644
Isnt this a good alternative for the driver board? No soldering required http://cgi.ebay.com/CNC-3-Axis-Stepper-Motor-Driver-Board-Controller-TB6560-/230532528366?pt=LH_DefaultDomain_0&hash=item35accf38ee#ht_5179wt_932October 4, 2010 at 3:02 pm #3645
@ARVI, at first glance the specs look correct for what you’d need, and the price is certainly right. We are currently trying to source a cheaper driver board than the HobbyCNC, but the sub-$100 range has pretty slim pickings. If you do end up using this board, please do let us know the results and perhaps we can work it into future plan revisions.October 4, 2010 at 5:22 pm #3646
This thread looks promising. I haven’t read the whole thing, but it looks like others have purchased this board for a similar application (3 x ~3 amp motors).October 31, 2010 at 5:22 pm #3647
Got the board and steppers. Looks good and works well too. Tested it using Mach3. Chris I will update about results more once I get the other parts in order. I am building my machine using cemented particle board of 6mm thickness. http://www.youtube.com/watch?v=fm4ntYrfr08November 1, 2010 at 2:36 pm #3648December 10, 2010 at 10:47 pm #3649
I’ll be looking for a board pretty quick. Let me know how those boards are going. Thanks!
