LAMPS (Laser Arduino Mega Pololu Shield|SLA Printer) is an open control board and SLA printer design. The SLA Printer strives to be a low-cost, small footprint (It is only 200mmx350mm!), highly capable SLA Printer. The build platform size is currently 100mmx100mm, but could probably be increased by someone who is motivated to enhance the design.

Basically, use my design all you want! :) But, don't sell it. If you want an exception, contact me.

#LAMPS Board LAMPS is the PCB control board that rides on top of an Arduino Mega 2560. It provides Galvanometer control (Through 12 bit DACs). It also controls the laser, buttons, Z Stepper Motor (Through Pololu Carrier), End Stops, LEDs, etc... (It is the Brainz).

Version 1.0 of the LAMPS board has been manufactured and tested... I found a few issues with the board and am currently redesigning and removing a few unnecessary components for 1.1. Release date T.B.D.

#Firmware The firmware for LAMPS is a fork of Marlin (The best open source RepRap firmware I know of), and can be found here: https://github.com/beardface/Marlin-OpenSL The firmware is very much an active work-in-progress, and I encourage you to fork, and contribute.

##Some words of Caution

• Careful with 110-250VAC, it can --bite-- Seriously Harm you if you aren't careful
• Some 405nm Resins can be toxic while curing- take the appropriate measures to ensure you are working in a well ventelated room
