Printhead Collision detection

Sat Nov 19, 2016 3:33 pm

If you're wanting some automatic built in protection so you don't have a printhead strike on the platen you can do this with a laser beam and light sensor.

Once the beam is broken you could have the code eject the platen, stop the platen or if you have motor controlled height you could lower your platen until the beam hits.

I've attached a sample file to show how to do it, it is fairly easy.
