What post processor are you using?
Could you post a copy of the tap file here.

The saving issue could be a problem with your license. What does it say in Help->about?

For the calibration, make sure you have the display set to 'Mask' or 'Mixed'. Is the dot flickering or breaking up? If so, try experimenting with the brightness slider.

What happens when you try to calibrate?

This is because you are using different layer names in your drawing than the cut operation was last set up to use. Simply drop down the layer selection list box and select the layer you want to cut.

Leave everything on one layer and do an 'outside offset' jet cutting operation. In your cut operation go to the 'cut path' tab and make sure optimisation is set to 'auto' and 'Cutting rules' are set to 'keep parts together'. SheetCam will automatically reverse the cut side for the inside of your par...

SheetCam figures it out for you and automatically reverses the cut side for inside contours.

There are a couple of ways of doing this in SheetCam. Fully automatic: In SheetCam open your cut operation and go to the 'Cut path' tab. Make sure Optimisation is set to auto and set the cutting rules to 'Keep parts together'. Make sure both the inside and outside contours in your drawing are on the...

Sometimes OnRapid can be called when X,Y,Z,A axes have not changed or have only changed by a tiny amount. In that case it will just output "G0". On the next call to OnRapid, it knows that G0 is active so it does not output G0 again.

Looking at that post, the height of the surface of the pipe is passed to the touch-off subroutine. Your touch-off subroutine needs to set the current Z position based on that value.

I had a quick look at the code and cannot see anything obviously wrong. Does the Langmuir controller have an option to pre-pierce your parts? If so it could be that you have that turned on.

I just had another look at the g-code and something looks wrong. What post processor are you using?

If the file cut correctly before the gearbox change it must be an issue with your machine. I have to admit I can't think of any obvious reason for it to do that.

If you set the ramp angle to a shallow angle it will have a similar effect.

In most cases I recommend putting all of your part outlines on one layer. If your drawing includes the outline of the scrap, put that on a different layer. Now you can use an outside offset and let SheetCam figure out inside/outside offsets. In your cut operation go to the cut path tab and make sure...

In your cut operation go to the 'cut path' tab and enable 'minimise thermal distortion' and set the distance to something like half the width of your part.
If that doesn't fix it I can modify the post for you.
