I am making a sign for a friend and suffice to say I am learning a lot. After a failed cut and finding and fixing everything I found in Vcarve Pro I cut the file and it worked great, I called it spot on perfect. I wanted to change one dimension the outer circle (wanted it wider to contrast the inner circle) within the file so I did and saved that individual tool path. Go to cut all the tool paths (6 total tool paths only changed 1) and it doesn't cut right. Should I recalculate all the tool paths when I change just one then cut them? I don't understand how changing on tool path is affecting another one. I sure hope this makes sense... I have attached two pictures one showing completed test cut that looks great. The 2nd one is the holes in the scissors that are off.
I am going to go thru each tool path again and see if anything changed (I doubt it) and try again. FYI the size of the project is 24X24 and that is why there is 2 inch on top and bottom that is not cut, that is what I hold the project down with I am running an AR 4 basic.
thank you for your help.....

It looks like your origin changed.

After you make any change to your project, you should recalculate all your tool path's, run the the simulation and see if it looks like it is cutting correctly. If it doesn't look correct, something is wrong.
Once it looks correct, save everything again, including all the tool paths.
When I make a correction, that is what I do every time. It saves from making too much scrap.

I agree with stevem. Even when Aspire tells me it has recalculated the toolpaths I'll do it again. I also like to take that time to review just what I'm doing with each toolpath. It's easy to forget to change the bit to Outside/Right versus On or Inside/Left. I have a 4 hour cutting job coming up tomorrow, maybe, and you can bet I'll be going over everything before the wood hits the CNC table.

It looks like your origin changed. agreed but why? I know you probably dont know but the previous tool path cut fine....I will recalculate all tool paths again and see how it goes.
Thank you....

It saves from making too much scrap. I will certainly do that from now on, I would have thought changing a tool path that had nothing to do with something else would have such a negative affect. You can bet I will recalculate all tool paths and look at preview to ensure its right (I just did this and it looks great).
Thank you

I will start to do that from know on (just did it and preview looks great) just frustrating when you make on minor change to a different part of the file and it screws up. I am sure every tool path is connected in some way but not smart enough to say what it is.
Thank you

this is the preview after recalculating the tool paths lets see if it cuts this way tomorrow. If it doesn't anyone want to purchase a used CNC LOL... Attachments:

When you changed the outside circle, you may have accidentally changed something else. Otherwise, you wouldn't have had a problem.
After I make a change to my project, I recalculate everything, save the the toolpaths and then run the simulation to make sure I get what I wanted in the change. After that, I'll copy my new toolpaths to a USB stick and cut out the project.
You also have to make sure you don't change your orientation.
I have done that and ruined pieces because I'm stupid and didn't notice my error.

You may be right I could have changed something by mistake and did not catch it I ran the file today after recalculating everything several times and it ran fine. Guess a good learning experience for me and others. You cant just change a one little thing and thing all is good...
thank you.

I have made many scrap pieces and know what it is like! All it takes is one simple mistake. Changing piece orientation and not changing the tool path and you have another scrap piece, forgetting to reset Z zero after changing a bit. Stuff like that that ruins your day.
