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

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

* 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, z-axis motor (really protrudes down), slow hinge on the cover and a watercooler-to-be.
