There probably isn't a binary answer (will/won't work), but rather a question of how well the alternative will function.</p> <p>Mach3 should work. </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-574 Wed, 18 Aug 2010 05:46:11 +0000 karandex 574@http://diylilcnc.org/forum/ <p>at least can u tell how many volts i need ?<br /> can i use mech3 as software ? </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-573 Tue, 17 Aug 2010 22:46:43 +0000 Taylor 573@http://diylilcnc.org/forum/ <p>Karandex,</p> <p>Looks like you'll have to figure this out on your own. We can give you ideas or point you in the right direction, but this is ultimately a DIY project. Good luck! </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-572 Tue, 17 Aug 2010 19:12:07 +0000 karandex 572@http://diylilcnc.org/forum/ <p>so is it ok to use an computer ATX power supply instead of build from scratch as shown in link ? </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-571 Tue, 17 Aug 2010 16:23:11 +0000 Chris 571@http://diylilcnc.org/forum/ <p>@karandex, I'm not sure what the wattage requirements for the HobbyCNC board are, but I'm sure you could figure it out based one the transformer specs. </p> <p>You are right that threaded rod or acme screws would increase the torque quite a bit. We tested an early version of the Z-axis using threaded rod and found that it wore down pretty quickly. Acme rod is more expensive, but it stands up to the friction much better. </p> <p><a href="http://buildyourcnc.com/blackToe2x4v40.aspx">Here's another drive solution</a> that might be cheaper than acme rods, yet more durable than threaded rod. </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-570 Mon, 16 Aug 2010 18:11:03 +0000 karandex 570@http://diylilcnc.org/forum/ <p>thank you for reply<br /> that will decrease my cnc cost a LOT. i am planing on using atx as of link. Would it be ok? how many watt atx i will need. I know it will be cheaper if i make powersupply ground up but wil ATX i get a case and fan system which is already tested and safe.</p> <p>One more thing comes to my mind if i get lower torque motor then i think that using threaded rod instead of acme rod will be better as they have lower pitch then acme rod and will provide more torque in linear direction . Whats ur say </p> http://diylilcnc.org/forum/topic/driver-alternative#post-568 Mon, 16 Aug 2010 17:36:27 +0000 Chris 568@http://diylilcnc.org/forum/ <p>@karandex, I'm not sure what the shipping charges would be. I would recommend contacting Dave Rigotti at HobbyCNC to discuss those details. </p> <p>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 <a href="http://diylilcnc.org/downloads/">downloads</a> page), but it may be easier for you to find one locally. </p> <p>You will need to solder the electronics together, so a good soldering station is important. </p> <p>There is <a href="http://www.mikebeck.org/cnccontroller1.html">another site that sells the kits already assembled</a>, in cases with transformers. Of course this adds to the expense, but it may be worth it in your case. </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-567 Mon, 16 Aug 2010 17:25:25 +0000 Chris 567@http://diylilcnc.org/forum/ <p>karandex, thanks for the info. Just to be clear, HobbyCNC does offer a board-only option that works with a variety of non-HobbyCNC motors. You could also use the HobbyCNC EZ board instead of the Pro Chopper, though this would limit your ability to add 4th-axis operations in the future.</p> <p>The 300oz motors we specify are definitely not mandatory; in fact we are realizing that they are probably overkill for a smaller gantry like that on the DIYLILCNC. The motors you list should probably work just fine, you may just need to be a bit more conservative with acceleration. </p> http://diylilcnc.org/forum/topic/atx-power-supply-and-motor-alternatives#post-566 Mon, 16 Aug 2010 09:54:40 +0000 karandex 566@http://diylilcnc.org/forum/ <p>i found this pdf's from hobby cnc</p> <p><a href="http://www.hobbycnc.com/wp-content/uploads/2008/02/powersupply.zip" rel="nofollow">http://www.hobbycnc.com/wp-content/uploads/2008/02/powersupply.zip</a></p> <p>the reason i want to use the atx power supply, is its simple and i only want to by board from them, the motors are available to me and they dont offer a board powersupply combo, and you have to have motors.<br /> And does 300 oz in are mandatory ? How low can i get on power of these motors. for the time of post i have access to 10kg/cm motors.(about 150 oz/inch)</p> <p>thanks in advance </p> http://diylilcnc.org/forum/topic/driver-alternative#post-565 Mon, 16 Aug 2010 05:04:40 +0000 karandex 565@http://diylilcnc.org/forum/ <p>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<br /> ?<br /> I am from india so what would be shipping charges like ? </p> http://diylilcnc.org/forum/topic/hobbycnc-board#post-552 Thu, 05 Aug 2010 09:02:45 +0000 guerd87 552@http://diylilcnc.org/forum/ <p><a href="http://www.mikebeck.org/cnccontroller1.html" rel="nofollow">http://www.mikebeck.org/cnccontroller1.html</a></p> <p>Mike Beck sells assembled kits of the HobbyCNC setup including Power Supply and cables etc. I havnt used them myself before - Just know of them</p> <p>By the looks of the pictures he supplies the Pro board in the kit </p> http://diylilcnc.org/forum/topic/hobbycnc-board#post-548 Thu, 29 Jul 2010 17:25:42 +0000 Taylor 548@http://diylilcnc.org/forum/ <p>Very good!

There are several other controller software packages out there, like Mach3, as well as different controller-hardware setups like <a href="http://grbl.tumblr.com/">Grbl</a>. </p> http://diylilcnc.org/forum/topic/grbl-an-arduino-based-g-code-interpreter#post-524 Wed, 16 Jun 2010 14:33:19 +0000 Bill 524@http://diylilcnc.org/forum/ <p><a href="http://blog.makezine.com/archive/2010/06/grbl_an_arduino-based_g-code_interp.html">Grbl</a> is a mostly complete implementation of the g-code standard, written to run on an Atmega328-based Arduino. </p> http://diylilcnc.org/forum/topic/driver-alternative#post-522 Sat, 05 Jun 2010 02:04:24 +0000 DIYengineer 522@http://diylilcnc.org/forum/ <p><a href="http://www.arduino.cc/" rel="nofollow">http://www.arduino.cc/</a></p> <p>Use a Arduino controller. :) </p> http://diylilcnc.org/forum/topic/driver-alternative#post-521 Thu, 03 Jun 2010 14:30:52 +0000 Taylor 521@http://diylilcnc.org/forum/ <p>@karandex,</p> <p>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! </p> http://diylilcnc.org/forum/topic/driver-alternative#post-520 Thu, 03 Jun 2010 14:19:41 +0000 Chris 520@http://diylilcnc.org/forum/ <p>@karandex, the interface is generally done with a parallel port. See page 62 of the assembly instructions in the <a href="http://diylilcnc.org/downloads">downloads</a> section for more details on the computer-to-driver interface. </p> <p>Of the driver boards listed on your link (under Step &amp; 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. </p> http://diylilcnc.org/forum/topic/driver-alternative#post-519 Thu, 03 Jun 2010 10:04:03 +0000 karandex 519@http://diylilcnc.org/forum/ <p>i found some supported hardware from emc site.

I also want to know how to interface it with ,its very confusing.

The part 2 is purely going to be a picture slide show of the finished product so everyone can see with there own 2 eyes a quick reference. I modified a aluminum box that i already had to fit the electronics so its not pretty but she works haha. I will work on both tonight. Still waiting for a final quote from the laser shop.
