The Hpdfo is made to stay in focus with very little tolerance. by running the Hpdfo Len's you are basically defeating the purpose of the lens.</p> <p>I would check the X belt tension once the dust settles. This may be all that it is.</p> <p>Have you tried to move the graphic into another area of the table?</p> <p>Try running the graphic in question at 18 power 33 speed just as a test.</p><p class="edit_text">EDITED: 22 Jan 2007 by MIKEMAC</p> <hr /><a name="a5808_16"></a><p><b>From: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.16">#16</a>]<br /> 22 Jan 2007<br /><b>To: laserman (MIKEMAC)</b> [<a href="lmessages.php?webtag=EE&msg=5808.15">#15</a>] 22 Jan 2007</p> <p>Well, after trying several of the suggestions, I finally have acceptable (for me, and I'm picky) engraving. I owe you and Logojohn and Harvey and Carl a drink. If you're going to be in Vegas, I'll buy. It was a combination of several things that worked. I tried so many that I'm not sure what I did. I just saved the settings and I'm going with it. Thank you all very much for the help! </p> <p>I hate the learning curve.</p> <hr /><a name="a5808_17"></a><p><b>From: Dave Jones (DAVERJ)</b> [<a href="lmessages.php?webtag=EE&msg=5808.17">#17</a>]<br /> 22 Jan 2007<br /><b>To: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.16">#16</a>] 22 Jan 2007</p> <p>I don't know if I missed this in your posts or not, but is the image you are engraving a vector image or raster (or combination)?</p> <p>If it's a raster or combination, maybe do a test engrave using a simple vector image with a solid rectangle and see if it has any bands.</p> <hr /><a name="a5808_18"></a><p><b>From: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.18">#18</a>]<br /> 22 Jan 2007<br /><b>To: Dave Jones (DAVERJ)</b> [<a href="lmessages.php?webtag=EE&msg=5808.17">#17</a>] 22 Jan 2007</p> It's a vector image with solid fill. The bottom 20% and top 20% are filled rectangles that goes from edge to edge with text , so the banding was noticeable. The center portion is a lion's head & mane that merges into the bottom part with text in the middle. <hr /><a name="a5808_19"></a><p><b>From: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=5808.19">#19</a>]<br /> 22 Jan 2007<br /><b>To: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.18">#18</a>] 28 Jan 2007</p> <p>The answer appears.</p> <p>The dithering in the filled rectangles is conflicting with the DPI of the laser. Convert those to bitmap at an even multiple of the laser's DPI and it is solved.</p> <hr /><a name="a5808_20"></a><p><b>From: Awardsguy</b> [<a href="lmessages.php?webtag=EE&msg=5808.20">#20</a>]<br /> 28 Jan 2007<br /><b>To: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=5808.19">#19</a>] 28 Jan 2007</p> <p>Thanks Harvey, I will give that a try.</p> <p>As you know I had a problem getting to the EE site. I thought I'd try another computer. Haven't had time to try the fix from Computer Associates on the other 2 and I'm a little gun-shy about using my work computers until I've done all of the diagnostics.</p> <p>I appreciate your help with everything.</p> <hr /><p align="center">Show messages: <a href="lmessages.php?webtag=EE&msg=5808.1">All</a>  <a href="lmessages.php?webtag=EE&msg=5808.1">1-14</a>  15-20</p> <h4><a href="lthread_list.php?webtag=EE">Back to thread list</a> | <a href="llogout.php?webtag=EE">Login</a></h4> <h6>© 2025 <a href="http://www.beehiveforum.net/" target="_blank">Project Beehive Forum</a></h6> </body>
