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:

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]]
* Add the "Focus adjustment wheel":http://www.thingiverse.com/thing:18941 for the z-axis. This should be the first thing you cut with your LS3020. A real enhancement. 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, dot, z-axis motor (really protrudes down), second fluorescent tube, slow hinge on the cover and a watercooler-to-be.
h2. Maintenance
* Instructions Instruction about "cleaning the lens":http://laserscript.co.uk/phpBB3/viewtopic.php?f=9&t=234. 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 "Laserscript forum":http://www.laserscript.co.uk/phpBB3 and on the comparable machines' "FS forum":http://www.fullspectrumengineering.com/forums/viewforum.php?f=3&sid=7de46ba40b08fe566985b4c7220616e1 you might find an answer to other questions like leveling the z-table or installing different focal length lenses.
