WARNING: Do not look into laser with remaining eye. Pages to do with the Laser Cutter:


New auto z zeroing sensor

Replacement sensor is a TL-Q5MC1 inductive sensor. They are commonly available on ebay. We use a 1" aluminum cylinder as our chunk of metal to detect. This is the same setup we use on the smaller Laser Cutter.

new sensor mounted backwards
wiring for new sensor

The picture on the left show approximately how the new sensor is mounted. The sensor had to be mounted backwards AND the bracket had to be mounted backwards so it is out much further than it needs to be.

The picture on the left shows the wiring for the new sensor. Far left (red) is 24V power, middle is the output signal, far right is ground.

The main thing that needs to be done is a 24V line needs to be run to the new sensor. The other two wires are what was used by the old pen style auto z zeroing sensor.

Counter balancing the lid

The pneumatic cylinders on our laser were bad when we received the laser which cause some near accidents when the lid wasn't supported and came crashing down.

Fix yet to be done.
