Kern: Switching from Nonmetal to Metal

Click the LENS CHANGE button to align the head above the lens change hole in the back-left corner

Turn the knob until the head is at its highest location

Remove the airline from the head by pushing all the way in and then pulling out

Unscrew the head and remove by lowering the head into the hole at an angle

DO NOT DROP THE HEAD DOWN THE HOLE

Fully screw the metal head into the empty socket

Attach the airline to the metal head

Fully screw the capacitive sensor wire into its empty socket

Cut the tape holding the paper down

Roll the paper back behind the laser

While wearing gloves, remove the honeycomb and store under the Kern

This is easiest with 3 people

Vacuum the debris from underneath the grid

Add the metal grate. You may need both grates for a large job

Move the gantry about halfway back from the front of the machine to access the height follower switch

Turn on the height follower switch

Click ENABLE HEIGHT FOLLOWER in the test dialog menu

Turn the dial on the lens assembly until you see 4 small white lines, then turn the dial back to only show 3 lines so the 15 is in line with the white tick and there is a little bit of blank space after the 3rd white line. Otherwise, if you are cutting with oxygen, you're done.

If you're cutting with nitrogen, screw the focus back up based on the thickness of the stock, plus a 5 thou offset

Example: If my stainless stock is .06", I would turn it counter-clockwise two full turns (each turn is .025") plus 10 thou, and an additional 5 thou for the offset, so it should end at the 0 mark

The following steps are specific to oxygen. The same procedure is followed if using nitrogen instead

Open the oxygen bottle

Turn the oxygen on in the test dialog by selecting OXYGEN in the drop down menu

Purge out the shop air and fill the lines with oxygen by clicking TURN AIR ON and let it run for ~3 seconds

This can also be done from the cut dialog

Drive the head over the work piece

Click the height follower adjustment button N to lower the head to the work piece and then set the user offset

Ensure that there is a slight gap between the head and the work piece (about 20 thou)

Adjust the slider to raise or lower the head if needed to create the gap

Raise the head back up by pressing the height follower adjustment button N again

Set the user offset like normal (might be easier to do with the height follower down) and proceed with the cut

Congrats you can now cut all materials

As always post in #equip-kern if you have any questions

The next step is the advanced Kcam that shows how to change settings and do some advanced stuff
