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. It comes in different flavours, depending in the time it was bought. Differences found until now:

* The size of the bed is different (some machines were actually LS-3020pro sold as LS3020, with a bigger bed.





    11
    
    
    
* Some machines come with a flatcable for the endstops and X-axis, while others have JST connectors for the endstops and X-axis.

The "home" position has limit switches at (Xmax,Ymax) which the firmware uses on power-up to figure out where the head is located. Homing can also be performed manually from the I2cPanel.

* 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. Some machines have Z-axis adjustment already installed.

* 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.
