LaserGRBL is missing some buttons/options

LaserGRBL detect GRBL configuration and remove (hide) some options if not compatible with your firmware/configuration.

1. M4 Dynamic Laser Power Mode is available only if your controller is updated with Grbl v1.1 or next, with “laser mode” enabled in grbl config ($32=1)
2. Homing button ($H) is available only if Homing feature is enabled in grbl config ($21=1)
3. Speed and power override is available only with Grbl v1.1 or next
4. Line2Line engraving needs PWM support, if you uncheck “Support PWM” LaserGRBL remove the options
5. Centerline tracing is available only on 64bit OS
6. Z-Axis jog support can be enabled via menu “GRBL, Settings, Jog Control”

This list includes the most common cases, but it is certainly not exhaustive.

LaserGRBL also allow to add as many buttons as you want via “custom buttons”. With custom button you can create a button and insert the G-Code to recall when the button is pressed or released. For example is possible to create a button to turn on the laser at low power for focusing or trace a frame around job.
