This is a modified version of grbl to include the J Tech variable power capabilities (J Tech grbl version 0.9g) into the Inventables Master fork of grbl 1.0c (a work in progress). Also included is the ability to switch between laser mode and spindle mode without having to reload the firmware.
The .zip file contains a Readme file with more information. Please read the Readme file, it is short and contains information that you will need to use this firmware successfully.
Many thanks go to those who helped with the early testing. Shane, Jeff, and John worked hard to make this version available.@ShaneBell, @picengravertoo (picengrave.com), @JohnChamplain (picengrave.com)
Hopefully this will provide a more up to date version of grbl for the laser community, as well as provide an easy way to switch back and forth between the laser and spindle modes.
No claim is made for its suitability for any purpose, but it is made freely available for those who would like to use it.
Please remember that you are responsible for following safe operating procedures when using your Laser. Only switch to laser mode when all safety devices are in use.
Firmware download has moved to the update in the link above right.
