what he said :-)

I have to say, give me a cheap physical switch endstop over an optical any day.

My k40 laser has optical endstops. And even with a metal piece going into the slot - it didn't work till i'd bent the metal so that it was exactly in the middle of the slot.

But for some reason they are considered to be superior to normal endstops. Go figure.

And for gods sake: cheer up !

You got a helluva printer at a bargain price and amazon even gave you free money into the bargain !

What's a couple tiny little niggles ?
Sheesh - you do know that electronics are effected by excess negativity. It's all down to the quantums doncha know :-)

So cheer up and start beaming happy thought at the poor beast.
