Wire cutter post

Post by Marius Liebenberg mari... »

Hi Les
What post do you suggest I use with Mach for my hot wire cutter. The machine has 4 axis of movement. X with A and Y with B. All independent for cutting taper profiles. I want to cut straight profiles from Sheetcam though.

Hi Marius,

I don't have a post that does 4 axis but it wouldn't be that hard to modify one to do 4 axis as long as you only want to cut parallel. Do you intend to use the wire cutting plugin in SheetCam?

Hi Les
Yes I am going to use the plugin, It seems to provide a good solution for nesting many parts.
Which post do you suggest that I should use a a basis to work form?

Wire cutter post

Post by Les Newell les.newell@... »

Hi Marius,

Start with a normal milling/routing post. For example if you are using Mach3, use the Mach3 post. Edit the post and look for lines like this:
   post.ModalNumber (" X", endX * scale, "0.0000")
Immediately after those lines add this:
   post.ModalNumber (" A", endX * scale, "0.0000")

Do the same for the B axis and Y.

You can't use arcs with A and B axes so look for function OnArc(). Delete the whole function and replace it with:
function OnArc()
    post.ArcAsMoves(0.1)
end
This will break arcs into short line segments.

In the longer term I would like to extend the wire cutting plugin to handle dual axes and tapers but that involves some significant internal changes to SheetCam and I'm not sure how to implement them at the moment.

Les
