Vcarve - exrtremely long time

Hi all,
I have just finished some coasters, and the last part vas a simple Vcarve of a logo with text. And it calculated 6 mins for all coasters, but i took 2 hours :o it kinda surprised me.
Now … i think the most time took the z axis travel.

The material setting was 18 mm(that was the thickness of the original board) but the carve vas at 6 mm material thickness. The retraction haigth was set at 3 mm.

So… my toughts. As far as I understand it, i could set for this carve job thickness of the material to x mm and zero the surface of the carving and retract heigth to 14 mm so i would still be 2 mm out of base when moving to next coaster, as there is a 12 mm wall between each carve.

So my question is, would this speed up the process or would with those settings machine retract for each dot for 14 mm ? I cannot change logo writing to text, as it is a logo and cannot be changed.

Any other solutions for faster vcarve on deep surfaces ?

Thank you in advance,

With best regards, Miha

Which version are you using?

Where was the design sourced from/how was it made?

V carving or Advanced V carving (if using v7 or earlier)

Upload the file?

Hello,

I am using V7 Pro,

yes I think it would be the best if I just post the file.

Your are cutting quite a few items:

which has a time estimate of 40 minutes:

If you were V carving just the logo:

that’s estimated at 2 minutes (for a single copy).

If you need a chamfer, if you instead just apply a No Offset Contour:

That also takes just a couple of minutes.

Hello ,

I think it is the issue off all that unnecessary z axis movement.

That is slow on my S4.

The material of 18 mm I know it is a waste, but is all i got at the moment with no way of splitting it.

If you update to v8 the vertical movement should be much reduced, and if you use a No Offset Contour where possible, the vertical movement will be only that which is necessary to move into and out of the cut.

Sorry,

the 6 minutes was time shown in Motion.

Create says 2 mins, but in reality it took 18+ minutes for one job.

OK, you are already removing a lot of material, what if instead you used a separate file to reduce the entire surface down to the thickness you want?

Then you could use that as the top-of-material, and your retracts could be as small as you like.

Yeah … thinking over the logic of the code once again simple solutions are usualy the best :wink: It would be soo much more complicated telling the tool in which areas you need to be retracting only x mm and when the tool needs to be over the surface of the main board. Thank you all for your time. It enlightened me and now I know more about the logic behind this path.

Thank you,
