Encoders-steppers.- Following error.

[granado]

I have two cnc4pc breakout boars; one for step motors and the other
for encoders. Some one knows How can I configure mach3 to Stop if the steppers loose it (following error).

You probably need to write a VB script using the macro pump to read the encoders and compare them to the commanded position.

Yes that's what I read on mach forum when mach3 added the macro pump option. But seems that no one has written this macro.
Right now I only see that rogersmachine.net has done a Plugin for that, but you have to buy his encoder interface.

I would be glad if some one can help me to write this VS script to share.
