Feed, Plunge, and Spindle Power Rate Modifiers
Better Grbl Support can apply a multiplier to feed and power commands as they are sent to the machine. Using a percentage value you can scale to the desired rate.
Allows you to control the speed at which the machine moves along its X and Y axes. A Feed command is injected with the current feed rate to ensure grbl processes the speed change in a timely manner.
Allows you to control the speed at which the machine moves along its Z axes. You must wait for a command including a Z axis feed rate to be streamed to the machine for the modifier to be applied.
Allows you to control the RPM of your spindle (if supported) or power emitted by your laser depending on your setup. Like the Feed Rate Modifier, the Spindle / Power Rate Modifier is injected immediately using the current power level as its reference.
