AndyUK's Build - 1.2x1.0m Gantry

[AndyUK]

I can see why everyone posts a video when they get their E-Stop circuits working for the first time :) Its quite a nice amount of clicking and clunking going on.

Until you decide to leave the panel running for five minutes with the motor driver supplies latched in.

And then you smell smoke.

And realise that the 24V contactor you purchased has the confusing symbols "50/60Hz" following the 24V designation...

Oh well. Off to find myself a new 24VDC contactor... ;)

That video may have to wait - although I can attest to the fact that if the contactor short circuits, the PILZ will cut the power to it pretty sharpish.

Hi Andy
If it makes you feel any better I did exactly the same thing,
Whoops..
