Achieving a certain depth is balance in variation between the laser power and speed. Another thing I like about this motor, which is perhaps a little odd, is the very long cable. Where 3D printing is fairly robust to submilimeter bed misalignments, milling widths of under 14mils is an unforgiving process: cut depth variations of even 0. If using mach3 or emc, with a probe setup correctly, the program imports your pcb gcode file, adds a bunch of probe points to the beginning, then maps the z axis to match the boards contours. Use this option to save the gcode. An elaborate, but not optimal, optimizer sorts the trajectory to minimize the lifts and moves and then outputs the G-code again, along with the probe/adjustment tricks. This program is based on image-to-gcode depth map milling program that is integral to LinuxCNC. When cavity depths exceed. That's obviously complicated because files have to be > copied around during the job, so the interpolation within the g-code is > much more elegant. G-code is a unique code which the milling machine firmware can read and actuate the machine. ulp is opened, you will be asked to select a default G-Code profile; I selected generic.
