Starting Z point and travel when milling with xcarve pro

I am having great luck using fusion and easel with the x carve pro.  One issue seems to be that when I start a carve the z axis traveling to the component isn't high enough.  I use the wasteboard top as my constant Z (which I prefer) and doing so seems to cause the machine not to travel to the beginning of the carve at a high enough distance to avoid cutting the project.  Is there a simple way to have fusion tell the machine what z to start the travel? thank you

Which post processor are you using?

When you hit the Start button, does the Z axis perform any motion at all, or does it remain at the height it was at when you started the program?

I'm uploading the G code into easel.  When starting it moves to a z height that seems to be relative to the origin point.  But not high enough to clear the project itself if that project is higher than 3cm at least.  It clears anything under that.

 

You can see in the screenshot the travel to get there takes it right through the side of the piece....

It does move the z axis a little.  Just not enough.

Could you share your G-code here, as well as the Fusion file?

I'm basically looking for a way to get my cnc to raise the z axis to the starting z in the file... before it moves to start carving... but something that I can set once in the file itself and not have to redo every time I export the g code.  I tried changing the "entry" position on the first cut's linking tab but that didn't seem to do it.

Sorry for the delay in response, this thread slipped thru the cracks..

Give this post a try. What I've done is swapped the order in motion; Z first and then XY, rather than go to XY start and then move the Z axis.

 

TEST CAREFULLY!

Do you have a Machine Configuration, and if so, what happens when you delete it and just use the post processor directly?

I got it to post... I think I just forgot to select it... 😜

 

Running it now... standby

That worked like a charm! and was EXACTLY what I was looking for.  I really appreciate the great customers service.  Thank you so much...

Message 15 of 18

It's working well but is there a way to make the exit or return Z height match the height coming in?  I'm getting the same issue with the bit leaving the project when it's cutting the middle or far side.

Hmm. It would be pretty easy to put a hardcoded value in there, such as Z20.mm or similar. Storing the initial Z position and recalling that at the end isn't as easy (for me to do)

I get these if I finish on an inside cut. When the carve is done.

In your Post settings, what do you have your Retract behavior set to? If you set it to "Clearance Height", the last Z move should be above the part (per your Clearance Height setting in your toolpath)
