Re: Toroidal PS and E-stop contactor circuit and EdingCNC
The reason I had not responded because it would appear that minds have been made up.
Whether or not the regulated practice of implementing a Machine E-stop that removes all motive power has saved any serious damage to man or machine, is rather a moot point, as all the Industrial machines I have had experience working on, and any that I have put together in a custom fashion such as the Galil you referenced to, have had the required mandatory E-stop circuit applied.
It is impossible to know the result this has had on eliminating damage to machine or personnel !
There are an estimated 600,000 CNC machines in operation world wide, so who knows how many serious accidents could have potentially occurred without the feature, is impossible to know.
Personally I do not see what the problems are, as it is not as though a machine E-stop is in general use on a regular operational/machine-control basis.
Or at least should not be used this way.
And as already pointed out, those creating a machine in a DIY fashion, are able to build it in any form or fashion as they wish, without the regards for safety or industry regulations.
