  • Tool path Efficiency


    A quick question to the experts. When doing a simple vcarve sign why does VCarve have a tendency to jump around the project. Example, it's machining a word and gets halfway through it and then moves to another section to later come back and finish the word. Normally all vectors are selected at once and I let the program do it's thing.
    Is there something that I'm not setting up correctly? I'm just curious why this happens, I would have thought the program would carve out more efficiently.

    Thanks

      I don't know either but my guess is to stress wood in one spot to cause it to break or split.

          Must be the way the program is programmed. I didnt care for
          Vcarve trial for that very reason. You get what you pay for?
          Thats why some programs cost more than others.

          Im on a Multicam 3000 w/ Enroute.
          No such thing as jumping around, which is BS to begin with.
          Multicam has their own software, MachineTools I think? Proprietary?

          Anyone using Enroute w/ a Camaster CNC~WinCNC and does it do that?

          Was doing an engraving today on an old VisionEngraving machine
          and it was doing that. It's almost finished in one area and goes
          out to left field then comes back.

          Im looking to get Enroute Plus and hope I wont deal with that
          once I get a Panther 4x4 for home or use a copy & usb key from work.
          For that price they let you install it on multiple machines. Cool.

            If I understand the question properly, you don't think the software is machining in an order that makes sense to you.

            What order did you select them in? Which of the "Order" options have you selected?

            The program will start it cut at the closest vector to its start, then proceed to the closest vector to where it ends. Sometimes, maybe even most times, this results in a hodgepodge appearing order, especially when it has to go back to catch vectors that were missed. Usually this happens when "select all" or a selection (lasso) box is used.

            You can select vectors in any order you wish, and/or have them cut left to right top to bottom or in a grid pattern by checking the options on the "Toolpath Order" tab visible when the advanced machining option is checked.

            Once you check these options they will persist for the future. Just like most other software titles, you must select the options that you wish to use.

              Gary, thank you for making me understand something that should have been obvious but for my simple brain was not. As soon as you stated "Select all Vectors" a light bulb went off. I had wondered about the same as the others but I am not in a rush so I didn't care. Probably would not make much more than seconds difference anyway. Computers are not smart they are just fast which means we can make more mistakes faster. Garbage in and garbage out.

              I do appreciate fcfoley for starting the thread because I did learn something today. Kudos to all who participated and Gary for his expertise.

                    Select vector order is essential in many sheets I cut... any holes are cut first, dados, etc before the actual pieces are cut out thus minimal concern on movement of the pieces. Same with cutting out pieces, smallest first and proceed to largest... not the most efficient machine movement but the best in cutting parts..

                      To go along with this, also important to select the start point for each cut, especially if you are cutting smaller parts in a sheet and don't want them to move. Ramp the profile cuts, with the start adjacent to the largest uncut portion of the sheet.
