h1. HPC LS3020 {{>toc}} !HPC-LS3020.jpg! The HPC LS3020 is manufactured in China and sold by "HPC Laser Ltd.":http://hpclaser.co.uk/index.php?main_page=product_info&cPath=1&products_id=40 in the UK. h2. Power supply The HPC LS3020 is shipped with various types of power supply: The original supply has a couple of white headers: p(((. !320px-IMAG0231.jpg! The supply included in some of the July 2012 units has _green_ headers, some of them combined: p(((. !320px-Power-LS3020.jpg! The pinouts are described on the [[HPC original power supply]] and [[HPC July 2012 power supply]] pages, respectively. h2. Coordinates The coordinates of an HPC LS3020 laser with LAOS board should be set up as follows: !HPC-LS3020-coordinates.png! The "home" position has limit switches at (Xmax,Ymin) which the firmware uses on power-up to figure out where the head is located. Homing can also be performed manually from the I2cPanel. h2. Modifications * Replace the on-off laser power push button by a toggle switch, so the state is visible from afar - [[HPC push button mod]] * The 'Focus adjustment wheel":http://www.thingiverse.com/thing:18941 . This should be the first thing you cut with your LS3020. You only need two M10 nuts to fasten it. * A shaky video (7:08) of a comparable machine showing "some enhancement ideas":http://www.youtube.com/watch?v=5F78_zDuaxI: in-line red dot beam combiner, z-axis motor (really protrudes down), second fluorescent tube, slow hinge on the cover and a watercooler-to-be. h2. Maintenance * Instructions about "cleaning the lens":http://laserscript.co.uk/phpBB3/viewtopic.php?f=9&t=234 * A video (6:59) on the "mirror alignment and belt tension adjustment":http://www.youtube.com/watch?v=jLgekkOiMsY&feature=related of a comparable machine. * On the HPC lasers can be found at the Laserscript forum the comparable machine's "forum":http://www.fullspectrumengineering.com/forums/viewforum.php?f=3&sid=7de46ba40b08fe566985b4c7220616e1 you might find an answer to other questions like levelling the z-table or installing different focal length lenses.
