Probe G68 fatal error

Hi,

I have used probe G68 (Y axis)  and program confuses the axes. Instead change Y angle during face operation it changed Z axis. Many hours of work went to waste. Can you fix it?

 

Regards

I'm no Haas code expert, but it seems to look good to me?

Hi,
So why Hass was going down the Z axis when facing??

The code looks correct too from first glance. 

What machine do you have?

Have you ever used rotational probing before? 

Can you give a little more detail on what's happening.

As far as I know on the HAAS G68 only allows rotation around the Z anyway so something else seems to be happening.

Haas vf 6

Of course many times used that function.
Machine wrongly change rotation on the Z axis instead of the Y Axis. Thats mean the Z axis was decreasing height constantly while facing. It is a fatal error. The Y axis should be decreasing or increasing value due to use of g68.

The G68 rotates in the currently active plane.

So if you started that program from the top it should have been in G17 plane and therefore caused it to rotate in XY.
If you didn't start from the top but from line N25 for example, it can be a totally different story. Than it could have been in any plane mode and caused the Z to adjust indeed.

@AchimN can maybe an idea to add to the post to always add the G17 in the G68 line?

As @Laurens-3DTechDraw has said the G17 means that you should only have had rotation around Z. I'm confident the output code from Fusion should have been correct, however would like to get to the bottom of this. 

Can you please re run the code with no part in and see if the machine position of the Z axis is actually changing. 
(Yes you will have to put the part in to probe then stop and remove it so it doesn't potentially scrap another part, or change the tool length for your face mill)

Im wondering if the machine was machining correctly but the part was lifting during the cut.
