Depth of cut issues

[redandbon]

Leo: Also, if it helps, I am using an Amana 46125 1/8" upcut spiral bit for the profile cut.

ODD.

It does not look like wood chipping. It does look like 1/8 end mill cuts.

If you have cut this a few times, do the cuts look the same on all the samples, or is it random?

I am starting to thing there may be some mechanical issues with the machine.

Have you tried running at 50 IPM?

[redandbon]

Have only cut it once. I can reset to 50 IPM if you think that might help. I'll try cutting it again tomorrow and let you know. I'm starting to think I have machine vs. software problems as well.

Thanks,
Red

When you cut it again, after the run, move back to where you Z-Zeroed and make sure it's still at 0.
Same for X,Y 0,0

Red,

Delete the copyrighted model in your file, save it with another name and post this file.

Leo: Here's some additional pictures. This is the best my camera can do. Hope it helps.

Thanks Scott, I have been doing this. After the run, it goes back to the Z-stop I setup in V-Carve Desktop.

Red,

LGM: Are you talking about renaming the file I purchased online from Design&Make? If so, I've already done that, but if you think it might help, I can do it again.

Thanks,

No, your file embeds the Design&Make model, which is copyrighted, so you're not allowed to post it.

Make a copy of your Vcarve file, open this copy, delete the D&M model, save the file and post it. This file will contain all your toolpaths and your parameters.

I am re-cutting the piece based upon the inputs you have provided. I'll let all of you know after it's done in about 6 hours.

Thanks,
Red

LGM: I attempted to attach the file after deleting the D&M model, but it's too large (2MB).

Zip it then it should upload.

Here's photos of my latest run. There's some improvement, but it's minimal and far from what I'd like it to be. Most of my problems seem to be on the profile cut, with a few occurring during the finish and roughing cuts. I truly appreciate all the help you folks have been providing, but this one really has me scratching my head.

Thanks,
Red

Red,

I don't see anything in your toolpaths and the preview looks correct.

This would lead me to a post processor or mechanical issue. It looks like the roughing and finish toolpaths preformed well so I would tend to think the post processor was working correctly. And as you said it looks like the issue is with the profile cut. Did you create the vector boundary or use the one from D&M? Are you sending the toolpaths directly to the CNC or are you saving the toolpaths to file then loading them in the CNC and running them?

I don't think your machine is loosing steps.

Looking at the cuts it looks like your Z is dropping into or climbing out of the cut while moving to the next spot to cut. All the cuts are ramped.

If you are up to yet another experiment I'd suggest increasing your Z1 to something high, like .5, recalculate your toolpaths and run just the CrossProf toolpath on a piece of scrap wood.

That's my two cents....
