Laser cutter and other CNC

K40 Laser Cutter (40w)

Status: ✅ OPERATIONAL

Caution

DO NOT adjust the laser power (current) knob, as this will shorten the life of the laser tube.

Usage

Important

Make sure the exhaust fan is running when performing any cutting.

The fan does not need to be running very fast. At full speed, it will drag any loose items into the vent (eg: cut parts, small pieces of material, etc).

K40 Whisperer software is installed on the PC next to the laser cutter.

Usually recommended to raise the height of the material off the bed by 1-3mm (optimal focus point), depending on material thickness.

Bed geometry

Max material size is 359mm x 227mm. Max cut size is 316mm x 216mm. x=0 is 26mm from left, y=0 is 2-3mm outside the material area.

Material

Recommended to use Laser Ply or Acrylic

For cutting, max material thickness is 4mm. Will require multiple passes.

Notes

When using SVG:

  • Make sure you reduce the canvas size of your SVG file to match the object size.
  • Make note of the DPI you are using, as it most likely will be required on import.

When using DXF:

  • Make sure your DXF file is ONLY the geometry of the part (no dimensions, etc).
  • Software cuts outside edges first, which can lead to the part dropping out of the material and losing registration for inside cuts.
    • Better here to use or convert the file to SVG. Make all inside cut lines Blue (Vector Engrave), and all outside cuts Red (Vector Cut). Change the cut speed for Vector Engrave down to match the cut speed of Vector Cut. Do all the Vector Engrave operations first to do all the interior features till they have cut through. You can then do the outside Vector Cut operations to cut the outside of the part(s). This ensures the material does not move and does not require loading multiple documents (and possibly needing to manually align them).

  • Under Support (when enabled) change the default Support Overhang Angle to 46°. This will stop Cura generating supports for 45 degree fillets and edges. The printer should be able to do 50° overhangs with 0.2mm layer heights, if not larger (actual value depends on layer height to layer width ratio).
  • Under Build Plate Adhesion, if using Skirt, change Skirt Height to 1. ** The skirt prints first 10mm beyond the edge of the print. This will allow you to see if the plastic is adhering to the bed properly before the first layer of your object(s) start printing.
