Reads SVG and DXF files interprets the data and sends commands to the K40 controller to move the laser head and control the laser accordingly. Your mileage on this may vary, but this is 100% the first thing I’d check for before even powering up the machine.
So effectively the 20,000V machine was not grounded. The grounding wire was attached to a painted section of the chassis and further separated from it with plastic washers. ACTUALLY GROUNDED THE MACHINE! This is the biggest WTF I had to deal with with my particular machine. Bought a cheapo Win8 tablet to run K40-Whisperer off of, essentially giving the cutter an integrated touchscreen. Installed a remote kitchen thermometer to the coolant to monitor it’s temperature. Added a simple closet moisture trap to the electronics compartment, because I live in a literal swamp Threw out the cutting clamp thingy that came with it and replaced it with an aluminium sheet with holes Cobbled together an air assist from a CPU fan This interlock will shut down the laser tube if the lid is not fully closed, preventing you from accidentally burning or blinding yourself. Out of the box, these machines have no sort of safety features at all. This is to prevent the laser tube from exploding if the coolant pump ever fails. Installed a flow switch interlock, that will automatically shut down the laser tube if the coolant stops flowing. Threw out the coolant pump for a much more reliable and stronger one, that’s actually god damn grounded Threw out the fan that came with it and replaced it with a 440 CFM in-line fan Threw out the hose that came with it, in favor for a fire proof aluminium dryer hose
Made my own hose adapter that is ACTUALLY air tight
