your engraver has improperly tensioned belts.There are two possible causes of these situations: mechanical problems or configuration problems. Misalignment and inaccurate engraving result For example is possible to create a button to turn on the laser at low power for focusing or trace a frame around job.

With custom button you can create a button and insert the G-Code to recall when the button is pressed or released. LaserGRBL also allow to add as many buttons as you want via “custom buttons”. This list includes the most common cases, but it is certainly not exhaustive. Z-Axis jog support can be enabled via menu “GRBL, Settings, Jog Control”.Centerline tracing is available only on 64bit OS.Line2Line engraving needs PWM support, if you uncheck “Support PWM” LaserGRBL remove the options.Speed and power override is available only with Grbl v1.1 or next.Homing button ($H) is available only if Homing feature is enabled in grbl config ($21=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).

LaserGRBL detect GRBL configuration and remove (hide) some options if not compatible with your firmware/configuration. Having a correct grbl configuration is mandatory for the machine to have proper behaviour. Grbl on controller has a knowledge of the size of the machine, the number of motor steps to make a millimetre etc, this is known as “grbl configuration”. Linear move to the point X30, Y20 at programmed F speedĪbsolute positioning / Relative positioningĪ full documentation of g-code can be found here: Ī software called “grbl” that run inside the controller board interprets these commands and translates them into the corresponding motor movements and laser pulses. LaserGRBL use only a reduced set of command, but the full g-code set contains many more commands ( read more).įast move (positioning) to the point X10, Y20 at maximum feed rate G-code include a series of command for positioning, moving, tool management. LaserGRBL talk to your engraver in a standard language called g-code, that it was originally intended for CNC numeric control machine.
