Avoid going to Safe Z after each pass
Avoid going to Safe Z after each pass
Hello,
I am machining a pouch of 20 mm depth, with passes of 0.3 m, which means more than 60 passes.
At the end of each pass, the Z axis goes to Safe Z position then plunges at z-rates which is quite sloooooow.
Is it possible to avoid that?

It won't help you as you get further down into the material, but it should cut down some of the time.

Hi mobius,
Both are set to +5 mm, but between +5 and -20 it goes at z-rate

Michael,
I am not sure to understand...
In the G-code file, I can see a "G0Z5.0800" command at the beginning of each pass.
It would be really better with relative coordinates than absolute. I will suggest that to Vectric.

Re: Avoid going to Safe Z after each pass
The pocket toolpath always lifts before doing the next pass. On a simple shape it seems wasteful but there are many instances where if it didn't do that the move for the next pass would plough through material that hadn't been cut.

I would disagree the the pocket toolpath always lifts..

Re: Avoid going to Safe Z after each pass
That is only one pass though so it has no need to lift for a 2nd pass. The OP has 60 passes in his toolpath.

Re: Avoid going to Safe Z after each pass
10 passes, still no lifting...
And a side view with 60 passes,,,no sign of lifting...
Unless I'm misunderstanding the problem......
Try it my way and see what you get.

Hi,
This behavior can not be viewed in the 3D model.
Better than an explanation, here is the G-code :

Re: Avoid going to Safe Z after each pass
Yes, it is possible to avoid that. But only by changing your existing settings.
1) Increase the pass depth for the tool
2) Increase the feedrate for the Z (ramp in)
3) Add the "Rapid Plunge" feature to your post P: (page 6 of the postP editing guide)

Re: Avoid going to Safe Z after each pass
Pass depth and plunge speed depend on the spindle, tool and material. This can not be changed abritrary to get the software running faster !IslaWW wrote:1) Increase the pass depth for the tool

Re: Avoid going to Safe Z after each pass
There is if it's a big issue for you. Remove the moves from the g-code.
