Warning: REV4 boards have a stepper ground problem: This can damage the MBED or stepper driver. you need to patch the board!

Due to a problem in routing the REV4 PCB boards, there is a part of the PCB that is not connected to ground. This can damage the MBED and/or pololu steppers. You need to add a jumper wire to fix the problem.

See: http://redmine.laoslaser.org/issues/68

A number of bugs have been fixed in the firmware.
One of them is a bug in the setting of the laser engraving power (#59, #63) and bitmap engraving (#47).

Note: this version uses STATIC PWM. This means the power is not scaled according to the actual speed (see issue #36). So corners are possibly burned in a bit.
It is work in progress, but you might want to try it out.

To download this firmware: https://github.com/LaosLaser/Firmware/raw/master/laoslaser-29-12-2012.bin and save it on your MBED.
This version is compiled from the GIT sources (master branch) using GCC4MBED.
