The one who wrote the "Guerilla Guide to CNC machining[...]" (the one I posted a link to some other time) also recommends it. <a href="http://www.rhino3d.com/" rel="nofollow">http://www.rhino3d.com/</a><br /> But unlike AutoCAD it's not free for students, although students pay much less. That's why I'm using AutoCAD at the moment (alternatively, when I don't want to fire up a virtual machine running Windows I use qcad. But I've had quite a lot of trouble with qcad when opening dxf files made with gnuplot or AutoCAD). </p> http://diylilcnc.org/forum/topic/cnc-cut-files/page/2#post-1025 Sun, 29 Apr 2012 04:27:08 +0000 gera229 1025@http://diylilcnc.org/forum/ <p>What program did you guys use to draw the parts? Because I'm finding it kind of difficult to move around the layers and find dimensions and modify certain items in AutoDesk AutoCAD for some reason. Probably because you used another program?</p> <p>Also will I need to delete all the text prior to cutting? In CAD it showed that the text used the line command to draw rather than the text command to type so I have a feeling that it will actually cut the text out. </p> http://diylilcnc.org/forum/topic/cnc-cut-files#post-1024 Sat, 28 Apr 2012 21:46:04 +0000 gera229 1024@http://diylilcnc.org/forum/ <p>The red marks are the holes right?</p> <p>What material should I use for the enclosure? Ply wood, Masonite, MDF?</p> <p>I can also use steel and aluminum (I have access to a plasma cutter). BUT I'm worried about shorting the circuit as a result of that (well I can paint, but I don't think that's very reliable) </p> http://diylilcnc.org/forum/topic/cnc-cut-files#post-1023 Sat, 28 Apr 2012 21:21:57 +0000 Chris 1023@http://diylilcnc.org/forum/ <p>@gera229, nope, the Capacitor is just a label that would normally be scored (not thru-cut) by the laser. </p> http://diylilcnc.org/forum/topic/cnc-cut-files#post-1022 Sat, 28 Apr 2012 20:51:06 +0000 gera229 1022@http://diylilcnc.org/forum/ <p>I see. Cut sheet is in the layers which are turned off haha.</p> <p>Where is says Capacitor, is that part cut out? </p> http://diylilcnc.org/forum/topic/cnc-cut-files#post-1018 Thu, 26 Apr 2012 22:04:30 +0000 Chris 1018@http://diylilcnc.org/forum/ <p>@gera229 - bummer, looks like PartKart, the online CAM software site that hosted those files, has gone offline. I'll see if I can track down a copy. </p> <p>Meanwhile, here are the 6 panels you'd need for the driver case:</p> <p>(2) Driver Case Side [cut sheet 1]<br /> (1) Driver Case Bottom [cut sheet 7]<br /> (1) Driver Case Top [cut sheet 7]<br /> (1) Driver Case Front [cut sheet 7]<br /> (1) Driver Case Back [cut sheet 7] </p> http://diylilcnc.org/forum/topic/cnc-cut-files#post-1013 Wed, 25 Apr 2012 22:43:52 +0000 gera229 1013@http://diylilcnc.org/forum/ <p>Download link for CNC cut pattern is broken.</p> <p>In the drawing I think I found the case drawing on the right side, but there are only 2 panels. Isn't there supposed to be more for the complete case? And aren't there supposed to be holes to attach the board to with screws? </p> http://diylilcnc.org/forum/topic/revisions#post-941 Wed, 07 Mar 2012 16:04:02 +0000 Taylor 941@http://diylilcnc.org/forum/ <p>@T4b,</p> <p>The core v2 design is complete, but we're still finishing up the documentation. See <a href="http://www.flickr.com/photos/diylilcnc/6757291097/">this link</a> for details. I hope to release the rough draft by the end of the month.</p> <p>We tested some USB alternate boards, but were unable to settle on a solution that can drive large motors. We'll look at doing a geared-axis secondary release that could play nice with existing USB solutions, but that's further down the line. </p> http://diylilcnc.org/forum/topic/v2-electronicsdriver-board#post-932 Mon, 05 Mar 2012 20:19:21 +0000 Chris 932@http://diylilcnc.org/forum/ <p>@T4b, I don't know of a specific reason it wouldn't, but I haven't tested it myself. The TinyG can't run off EMC2 (or Mach3), so you could either use the terminal in Linux, possibly CoolTerm, or the <a href="https://github.com/rainbow-lazer/TinyP-CNCcontroller">Processing GUI</a> I whipped up. </p> http://diylilcnc.org/forum/topic/revisions#post-930 Mon, 05 Mar 2012 17:22:18 +0000 T4b 930@http://diylilcnc.org/forum/ <p>Could you maybe summarize what you've already done and what you still want to do to finish v2.00?<br /> And what do you think when it will be finished?</p> <p>I would build a v.1 instead of waiting, but I it would be a real pain to get those non-metric parts, I fear (probably with a lot of additional cost for shipping) and it would further increase cost to get a computer with a paralell port. </p> http://diylilcnc.org/forum/topic/v2-electronicsdriver-board#post-929 Mon, 05 Mar 2012 16:49:48 +0000 T4b 929@http://diylilcnc.org/forum/ <p>"Works via USB on Mac and Windows (Possibly Linux)."<br /> Is there a reason it shouldn't run on Linux? I went onto their site and they have a Linux version of the software they use to connect to it.</p> <p>As I'm a Linux user I would of course very much like it to run on Linux. </p> http://diylilcnc.org/forum/topic/v2-electronicsdriver-board#post-922 Mon, 20 Feb 2012 17:38:56 +0000 Chris 922@http://diylilcnc.org/forum/ <p>@Mike, we've done lots more testing with the TinyG. It's a great little board, very hackable on the software side (I wrote a little interface for it in Processing that I used for a couple of custom-CNC art projects).</p> <p>The limitation with that board (and any boards that max out around 2A per motor) is that the DIYLILCNC V1 design needs more torque than it can provide on the X and Y axes, which leads to slipping/stalling. This could be addressed by adding some gearboxes or lead screws to reduce the amount of torque needed to drive these axes. </p> <p>So for V1, looks like HobbyCNC is still the best option for torque/power and a robust software interface. It's also come down in price recently. </p> <p>We may try to add some gearing into the V2 design, which would open up more options for using different driver boards that provide lower current like the TinyG or pololu drivers. </p> http://diylilcnc.org/forum/topic/v2-electronicsdriver-board#post-921 Sun, 19 Feb 2012 02:55:31 +0000 Mike Ehrenberg 921@http://diylilcnc.org/forum/ <p>@chris, have you gotten any further with the motor driver selection for V2? </p> http://diylilcnc.org/forum/topic/v2-spindlecutting-tool#post-912 Thu, 12 Jan 2012 05:31:07 +0000 tj 912@http://diylilcnc.org/forum/ <p>What about an air engraver? Off the mighty ebay you can purchase one form around $40 US on up. I have a $300+ turbine one, in a pen style that spins 400,000 RPMs, most though spin 55,000 +/-. They have low volume requirements so an airbrush compressor can drive them. Come to think of it an airbrush might be a fun a attachment too.</p> <p>With a pen holder already designed, and at such low cost if you already have compressed air, seems like a worth while experiment.</p> <p>Also I'm contemplating on construction of a flood-able cutting table. This would require design modification, raising the X axis tracks, lowering the cutter, and getting another construction material involved. But when the task called for it, the addition of water would increase the longevity of cutters when working with harder materials, or rather soft metals, marble and such. </p> http://diylilcnc.org/forum/topic/revisions#post-901 Fri, 02 Dec 2011 23:16:33 +0000 T4b 901@http://diylilcnc.org/forum/ <p>As long as I can use it to cut the modified panels it's no problem for me.</p> <p>I guess I'll order the panel set as soon as it's available. </p>
