out of ideas
trying to do v carve inlay. you can see from pics the letter N has some left but it has been lowered. the letter W has some left. the letter S was the last thing cut but turned out perfect. I set z back up and ran it again. it ran the same path along the same piece of wood. i am confused because how could it mess up N and W but not the S. Vcarve software showed no errors when i was making it and it came out perfect on the preview screen. before someone tells me its the carve king machine first tell me how it can screw up 2 letters but not the last letter and i ran it twice over the same cut out with the same results. i posted 3 pics but it is 1 piece of wood and all 3 letters done at same time.

Re: out of ideas
My initial thought has to be: the bit(s) used to cut the piece differ physically from those specified in the toolpaths.
For v-carve inlay pocket the “S” has very little angle to the walls.

Re: out of ideas
I agree with Steven. All the letters seem to have vertical or very close to vertical walls so it doesn't like you're cutting with a v-bit.
Did you specify a clearance tool in the toolpath and only run the toolpath for the clearance tool rather than all the toolpaths created?

Re: out of ideas
Check you don't have more than one tool selected in the job set up as Adrian has mentioned, that could explain why it has left that extra material, why did it clear all the letter S well that may just be down to the width of the tool & you got lucky with the S, if you look at the W & the N the extra material is left where the letter is wider

Re: out of ideas
That's an endmill though rather than a v-bit. The only way you can use that with a v-carve toolpath (the type of toolpath the vinlay uses) is to setup it as a clearance tool but you still have to set up a v-bit in the same toolpath.electrictermite wrote: ↑Mon Sep 27, 2021 12:51 pmi used the Amana 46200K and the Amana vectric toolbase download.
When you press Calculate the software then creates one toolpath for each clearance tool and a toolpath for the v-bit. You then have to run each toolpath in order ending with the v-bit one.
If you can attach the actual VCarve (CRV) file that you have then it will make it easier for us to tell you exactly what you need to in relation that job.

Re: out of ideas
After a cursory look at the tool definition image I'd have to question the 70% step-over. Step-overs greater than 50% can cause problems with pocket-like toolpaths.

Re: out of ideas
I'm not so sure it is a Vcarve toolpath Adrian, I think it could be an inlay toolpath, the CRV file will tell us one way or the other if the OP can provide itAdrian wrote: ↑Mon Sep 27, 2021 1:13 pmThat's an endmill though rather than a v-bit.

Re: out of ideas
Possibly, it's one of those terminology things again. People say vinlay, v carve inlay, vcarve inlay etc when they all mean the Zank method rather than the built-in inlay.
What makes me think that it might well be a v-carve toolpath is that the only way I could even get close to reproducing what the OP pictures show is by running a clearance toolpath but even that isn't exactly the same.
It may well be the 70% stepover if it's the inlay pocket toolpath being used but the letters would need to be quite small for it to behave like that.
Hopefully a file will be forthcoming as I'm really curious now. I do love a good mystery!

Re: out of ideas
This post seems to be an extension of that post: viewtopic.php?f=2&t=38311&p=279011#p279011
If the "that" post never got resolved then "this" post probably won't either. Long and short: if the preview is good and the execution is not then 999 time out of 1,000 (made up statistic) it's the execution where you should look.

Re: out of ideas
You've got "Project onto 3D model" checked but there is no 3D model in the job. I'm pretty sure that's not the issue but it has been known to cause issues with that set when it shouldn't be.
As Steven says if you didn't get to the root of the issue last time then it's probably going to still be there.

Re: out of ideas
I just had another look at the preview compared to your pictures and it looks like a machine issue to me. Compare the left hand side of the W from the picture to the preview. In the preview the sides are parallel in the cut they're widening out and the bottom curves of the W are a lot bigger.
Similar thing with the N. The centre section is far wider than in the preview. In each of those areas you have that island. With the S it's constant curves rather than straights so the loading on the bit is different.

Re: out of ideas
I see things I would not do - BUT - I don't see enough wrong that it would not work.
First you mount one piece of wood and run the first two toolpaths.
That makes the inlay female pocket.
Then you remove that first piece
Then you put a new piece of wood and run the second two toolpaths.
That makes the male insert.
Is that what you did?

Re: out of ideas
Should I try to run clearing endmill with pocket function and follow up running vbit with vcarve funtion to clean up
