The HPC LS3020 is manufactured in China and sold by HPC Laser Ltd. in the UK.

Power supply¶

The HPC LS3020 is shipped with various types of power supply:

The original supply has a couple of white headers:

The supply included in some of the July 2012 units has green headers, some of them combined:

The pinouts are described on the HPC original power supply and HPC July 2012 power supply pages, respectively.

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.

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 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: 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.

Maintenance¶

• Instructions about cleaning the lens.
• A video (6:59) on the mirror alignment and belt tension adjustment of a comparable machine.
• On the HPC Laserscript forum and on the comparable machines' FS forum you might find an answer to other questions like leveling the z-table or installing different focal length lenses.
