If so, you should already have slots on your panels. If you somehow have the overall shapes but are missing slots, I suppose it's possible you could make a little router jig to add slots by hand. Let us know if you go this route and perhaps we can help advise on building a jig.

In retrospect they are the obvious way to go. I had problems anyway locating barrel nuts. Any suggestions on cutting slots at this stage? Jim Chris on "Before you get panels cut, read this post" http://diylilcnc.org/forum/topic/before-you-get-panels-cut-read-this-post#post-129 Fri, 04 Dec 2009 17:44:08 +0000 Chris 129@http://diylilcnc.org/forum/ Darrel, this should be no problem structurally; If you leave everything as is, the tabs will not fit as snugly and may stick out too far. So you may want to adjust the tab & slot lines in the DXF to more closely match that material depth. Here are the measurements we used: <img src="http://diylilcnc.org/wp-content/uploads/2009/12/Picture-59.png" /> Here's a link to a drawing of just the tab and slot shapes to use as a reference: <a href="http://rainbowlazer.com/3d/rhino/cnc-routing-technique-for-milling-interior-corners/">Vector path for 1/4″ laser-cut t-bolt joint (.dxf)</a> In any case, I'd recommend doing a test if possible to see how the fit is.

Or can I use this? Thanks, Darrel Chris on "Before you get panels cut, read this post" http://diylilcnc.org/forum/topic/before-you-get-panels-cut-read-this-post#post-106 Wed, 25 Nov 2009 21:45:49 +0000 Chris 106@http://diylilcnc.org/forum/ FYI everybody, we just noticed there is one piece missing from the driver board case. It's the top panel and we're working on getting it into the DXF. I will post in the revisions topic when we've updated it. Thanks! Chris on "Before you get panels cut, read this post" http://diylilcnc.org/forum/topic/before-you-get-panels-cut-read-this-post#post-77 Sat, 21 Nov 2009 01:18:53 +0000 Chris 77@http://diylilcnc.org/forum/ Bill, the slot holes in the CAD files are set for 0.24". The masonite that we were working with was about 0.2"-0.23" thickness, but we actually found it was good to have a little bit of play in the T-bolt joints. Another option for those of you better-versed in CAD is to find the exact depth of material being used and adjust the slots accordingly in the file.

Taylor on "Before you get panels cut, read this post" http://diylilcnc.org/forum/topic/before-you-get-panels-cut-read-this-post#post-75 Sat, 21 Nov 2009 00:16:36 +0000 Taylor 75@http://diylilcnc.org/forum/ Now that we've had a chance to follow some of your posts on the forum, a word of caution. Although the CAD files that we released in the Download section are the very same that we used to build a functioning DIYLILCNC here in Chicago, please bear in mind that we were sitting right in front of our laser cutter when we ran those files. As many of you know, there's nothing so difficult as getting a CNC machine to run a file right the first time. For those of you that are preparing to contract out your panel cutting, we strongly advise getting in touch with the service provider first to talk through some of the potential issues. Primary among potential problems is the tendency for stock (such as Masonite) to vary widely from its listed factory thickness. Even though we dealt with a consistent supplier, we found that 1/4" Masonite varies in actual thickness between .20" and .25". This won't affect the tab component of the project's joinery, but it will effect the slot component (found throughout the design). Wherever possible, we recommend that you pick a service provider that you can visit in person. Failing that, try to get someone who is a fellow maker (and more likely to cut some small fit tests for free before you take the plunge). It also seems that some of you are banding together in Canada and Australia to share build notes. That's great! Once you've identified good service providers perhaps we can list them on this forum. If we're really lucky, we can get them to keep the file on file, smoothing the way for future project builds.
