Re: [Emc-users] management of limit switches

2009-04-23 Thread Rob Jansen
Robert, as also written by others, the 'override limits' button on the (Axis) user interface allow you to back of from the limits. But in general, the limit switches should be placed at such a location that these are never hit during normal operation. On my machine the travel of the Y axis (tha

Yes,that is exactly what I am doing -- limit switches in both directions of X and Y axis are common. With a bit of work I could re-wire the limit switches to provide *four *signals: X+,X-,Y+,Y-. I suppose what I am asking for is a sort of "software" implementation of the same idea. This seems to be

[Emc-users] management of limit switches

2009-04-23 Thread robert melville
I have just started to use EMC2 with a homemade tabletop mill and like it a lot. However, here is some behavior I have seen in another controller which I find very convenient.Is there some way to get EMC2 to do this also? Suppose I am running my XY-table in the positive X direction and I hit the X
