Residue on versaflex</a></h1><a name="a6724_1"></a><p><b>From: Lisa (DUNKAFIFE)</b> [<a href="lmessages.php?webtag=EE&msg=6724.1">#1</a>]<br /> 23 Apr 2007<br /><b>To: ALL</b></p> <p>Hi everyone! </p> <p>I've been lurking around reading messages off and on for the last year or so. Everyone is so helpful with issues/questions, that I thought I'd try asking one for myself.</p> <p>I've got what I hope is a fairly easy question to answer. I recently purchased a Trotec laser engraver and have stumbled on a problem that I do not know how to resolve. I hope someone here can help!</p> <p>My issue is with laser engraving/cutting labels for trophies. I use the laser to cut them out after the text engraves. I use Versaflex (sp?) (Marco/Discount Trophy product like Flexibrass knockoff) in black with gold underneath. On many of the labels but not necessarily all in a given run, I end up with a residue at the bottom of the label. See my rather pitiful diagram below with the x's denoting where the residue ends up. </p> <p>+--------------cut line----------------------+<br /> ! !<br /> ! Label text !<br /> ! !<br /> xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx<br /> +--------------cut line----------------------+</p> <p>I'm assuming this should NOT be the case as it's a pain in the you-know-where to remove when I can get it off! </p> <p>Unfortunately, I don't remember the power, velocity, etc. settings I use for the cut. Air-assist is on, if that matters. The Trotec laser comes with software that includes settings for use with Flexibrass, so I have defaulted to those settings. If this info is necessary, let me know and I'll provide it in a subsequent message.</p> <p>The residue does not appear to happen on the silver or gold versaflex... just the black. </p> <p>Also, if you know of an easy way to remove the residue, I'd love to hear it. I've tried Goof-off and Goop-off and another couple of kinds of adhesive remover, but none work especially well.</p> <p>Any ideas? I'd appreciate it!</p> <p>Thanks in advance!</p> <hr /><a name="a6724_2"></a><p><b>From: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=6724.2">#2</a>]<br /> 23 Apr 2007<br /><b>To: Lisa (DUNKAFIFE)</b> [<a href="lmessages.php?webtag=EE&msg=6724.1">#1</a>] 23 Apr 2007</p> <p>It could be two different things that may be causing that. Smoke residue or heat aberrations in the surface.</p> <p>One solution may be to use the minimum power that will cut through the material.</p> <p>Make some 1/2" horizontal lines, each at a different power/speed along the left edge of the layout. Put in the material a slight bit to the right of the left edge, then vector it. Use the lowest power that cuts through the piece.</p> <hr /><a name="a6724_3"></a><p><b>From: Laser Image (LASER_IMAGE)</b> [<a href="lmessages.php?webtag=EE&msg=6724.3">#3</a>]<br /> 23 Apr 2007<br /><b>To: Lisa (DUNKAFIFE)</b> [<a href="lmessages.php?webtag=EE&msg=6724.1">#1</a>] 23 Apr 2007</p> <p>I use denatured alcohol to remove smoke residue from most substrates - wood, plastic, etc. but never for acrylic!</p> <p>Don't EVER clean Rowmark with alcohol and stack them though...

Adjusting your settings so that you get a quality engraved image but not too deep and so that you just barely cut through the material will reduce, but not eliminate residue.<br /> <br /> You can try bottom up engraving which may help a little.<br /> <br /> I clean mine with denatured alcohol. Don't stack them wet but DA will do no harm. If I'm engraving something with a white core I may soak them in a citrus/water solution before attempting to clean them.<br /> <br /> Leave your air assist on, especially when cutting. <hr /><a name="a6724_6"></a><p><b>From: Lisa (DUNKAFIFE)</b> [<a href="lmessages.php?webtag=EE&msg=6724.6">#6</a>]<br /> 23 Apr 2007<br /><b>To: ALL</b></p> <p>Thanks for everyone's reply.

He is quite an artist.</p> <p>I do not use all the Trotec settings as each machine varies a little. I even find myself tweaking these from time to time depending on color. Red and Black seem to be harder to engrave than gold and silver.</p> <p>On very thin material engraving too deeply can cause the material to become brittle.</p> <p>Another thing to watch for is the cap thickness.

Now I get the residue at the bottom of the plate and at the top of many of the letters. </p> <p>So, I tried using my same settings and just downing the power by 5 (to 15) and unfortunately, that didn't help. I'll try it with less power when I'm not so busy, but in the meantime, I'll buy the denatured alcohol and give that a shot. </p> <p>I do have air assist on... but my vacuum is turned down fairly low. I'll turn it way up and see if that matters.</p> <p>BTW, I do get the dust residue as well. That just wipes off like powder.

While our machines are the same wattage they operate at different speeds.</p> <p>One of these days we'll all get on the same page as far as adjusting the power settings and speed setting to actual watts and inches per second.</p> <p>For example on our machines if we're at 80% power that would be 36 watts, if you know the raster speed of your machine and it's 100 inches per second, at 50% speed you'd be at 50 inches per second. Therefore if we related just actual wattage and actual speed in IPS we could relate better to the settings offered here.</p> <p>The real answer will lie in the test results you personally find to work best.</p><p class="edit_text">EDITED: 24 Apr 2007 by MIKEN</p> <hr /><a name="a6724_20"></a><p><b>From: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=6724.20">#20</a>]<br /> 24 Apr 2007<br /><b>To: Mike (MIKEN)</b> [<a href="lmessages.php?webtag=EE&msg=6724.19">#19</a>] 24 Apr 2007</p> I made that suggestion strongly two years ago.
