The real job is done by a very powerful software called "grbl" that run inside your control board.

When you import an image and use "line2line engraving" you can specify what range of power use for S-Min and S-Max: LaserGRBL will suggest the same values configured and use the full laser power to map the grayscale values of the image black pixels will be mapped to S-Max and white pixels to S-Min and it is good to left it as-is.

A common GND between control board and driver is required. The connection between GRBL control board and laser driver should look like this. TTL and PWM are used as a synonym to indicate a technique with which the laser power is modulated to obtain different levels of engraving. It is very difficult to completely cover all the possible existing hardware configurations, however we can find a common scheme in all systems.
The VFD that this is potentially a very dangerous device that is designed to be commissioned by a licensed electrician.This guide is designed to help those who have difficulty with the connections necessary to use the laser. Lastly, an opening in the board to access the smoothness adjust trimpot, which can largely be ignored. If your motors are running overly hot then turn this down a little, if you are suffering from lack of power turn this up a little. The desired resistance measurement between the two terminals is 2. There is also measurement point beside each trim pot marked in blue. Note that this is not smoothness tuning the trim pot mentioned in the manual. This takes place of the resistor to be soldered that is mentioned in the G manual. The GRBL Gecko controller has a trim pot for setting the current limiting of each stepper motor which are circled red in the image below. Please ensure the charge pump switch on the gecko is turned off. The cooler will be marked for either 12V or V connection.

As the spindle is slowing to a stop, check that it is spinning clockwise when looking from above, should it not be any two only of the U, V, or W outputs that the spindle cable is connected to can be swapped to change the direction.
Once the above is complete, complete steps 1 through 4 of the software setup steps, and return here to test the motor as per below. You may use the up and down arrows to skip to a new parameter and a short press of the navigate button to enter and exit a parameter. To program any parameter, press and hold the navigate button for a few seconds, at which point the keypad will display the last parameter configured, initially 1. The following diagram describes the control pad functions of an E3 inverter, as described in section 5 of the manual. The following information configures the E3 for 3DTeks standard use case and this information may not be appropriate for other uses. The invertek E3 VFD has several important and several optional parameters to be set before attempting to operate. Our implementation of this device overrides some of the information provided in the manual, for example, the motor current tuning and motor wiring. Please contact 3DTek for any assistance wiring up or configuring these devices. These may or may not be useful for other Gecko use cases.
