Laser Cutter

Revision as of 23:33, 11 November 2012

Theory / General Info

Laser

• Good notes on controlling the intensity of the laser with PWM - Laser Power Settings Via PWM Can Fool You

Optics

Linear Motion

Electronics

• Potential arduino shield to use with LasaurGrbl - LasaurShield

Software

• Potential controller software based on Grbl- LasaurGrbl
• Software to run on Mac/PC to send G-code to LasaurGrbl - LasaurApp

Build Notes

• The laser cutter being built is based around the laser cutter on Buildlog.net
• Another good reference is Lasersaur
