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/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/how-to-video-controller-board-solder-and-assembly/page/2#post-541 Sun, 18 Jul 2010 19:39:30 +0000 Chris 541@http://diylilcnc.org/forum/ <p>See <a href="http://diylilcnc.org/forum/topic/hobbycnc-board?replies=3#post-540">this post</a> for a link to great, illustrated, step-by-step instructions for assembling the HobbyCNC Pro Chopper driver board. </p> http://diylilcnc.org/forum/topic/how-to-video-controller-board-solder-and-assembly/page/2#post-470 Sat, 01 May 2010 06:19:28 +0000 tkluysk 470@http://diylilcnc.org/forum/ <p>Hey DIYengineer!

All the hardware, driver control board, case, steppers, nuts and bolts etc. You pay shipping From Seattle. I will re-list on ebay if anyone is interested contact me diyengineer @ gmail . com<br /> Saves you like 250 bucks! Everything is in working order and hardware still in original packaging!</p> <p>This build has spring boarded me into a bigger machine, that unfortunately costs a lot more. Contact me if you have any questions!</p> <p>Laser is just to much in my area, and cutting out by hand showed poor results.<br /> Thanks guys! </p>
