Graphtec FC9000, not able to cut a 0.75" long octagon,

[ikarasu]

Forgive me if I didn't see the answer, as I saw the question asked a few times but didn't see an answer...

If you load it into cm4, and just cut vinyl without a print, without reading registration marks.. Do you get straight lines or does it mess up?


I would cut the shape, with a box around it like your last nest of octagons with no print, then see if the lines are straight compared to the outside box, or if they ever over like they do in your print. That would rule out the arms sensor.

Try something like my file below (sorry its sloppy just wanted to get the point across). Straight lines with overcut. From my understanding of the machine and your problem, the knife is not turning fast enough to get you your nice straight lines. Having extra lead in at the beginning of a cut will give the knife time to turn to the correct angel when cutting where the print is.

Yes but his file did not do that for me, which reminds me that was what I mentioned early on about a setting on the FC9000 that essentially does this. Read the manual section 7.1, 7.3, 7.7, especially 7.7.

I tried with all straight lines. joining the ends, and overtcut 0.004, didnt helped

sorry for typo error, want to say, as i have 1000 cuts in a small area, might take long if blade comes up and down 8000 times. wear faster. just guessing

In CM5 there is a setting to change cutting direction. Have you tried counter clock wise?

i tried didnt help

 

[gpslitt]

I think your problem is a mechanical issue with your cutter. Did you do the test I suggested on unprinted vinyl?

yes i did ..didnt work

Interesting find but the IL file with the curves did not do that for me. Cutting shape from IL-CM-FC9000-160.

curves are ok, just sharp corners is a problem

Check my post #44

First of all, thanks everybody for helping me out. At last after a month of research and tries, I have found a solution.

In Illustrator I just change the corners size from 0 to 0.005, which is not very visible with the naked eye, but CM5 don't consider the angle to be sharp anymore and consider as smooth rounded corner and cuts perfectly.

Thanks again everybody for the inputs.. I am very happy to be in this community, where everybody helps.
