    Re: BOBCAD 3D PRO WITH BOBART

    Just to clarify, you have 3 Axis Mill Pro with Bobart for each license? Did you deactivate the software from the computers they were initially installed on (if not deactivated, the license will...

    Re: stationary gantry milling table

    Speaking as someone who has a 4 or 5 ton 4'x4' stationary gantry router, made of 1/2" plate steel with flanges of 3/4" plate, I can tell you that there are some problems with the idea of machining...

    Re: BOBCAD & Nesting for a waterjet.

    From what I have been able to gather in this thread, the problem is that you aren't communicating what exactly you expect the software to do. Take that back to your conversation with the sales rep,...

    Re: Vcarve in V26 - arc moves not working?

    My initial experimenting seems to show that you don't get arcs in V-carve. That said, is there a quality issue when the parts are done? My experience has been that with modern controllers, its almost...
  6. Re: How big of an STL file can Bobcad handle (v26) ??

    I think the most I've been able to do is about 10 million faces in Bobcad. I have a file somewhere that is the largest I've been able to do, but it would take some time to find it. Takes forever to...

    Re: V27 3 axis Pro radius toolpath question

    Depending on the part, it sounds like Z-Level may work just as well or better in that application. Just depends on how three dimensional the roundover is. If the roundover stays on the same plane,...

    Re: V23 vs V28

    You can continue to use it in demo mode, which allows you to really learn the software in depth since the only thing that is eliminated is the ability to do "Pro" simulation and the ability to post...

    Re: V27 3 axis Pro radius toolpath question

    "G91 G28 Z0" is as follows:

    G91 tells the machine to switch to incremental moves. This means that each value given is the distance from the current position which the machine should go. G28 tells...
  11. Re: Upgrade Motivation from V24 to V28 or V5 for Solidworks

    To answer your questions:

    1. Will I be able to set up tools and materials in libraries with feed and cutter speeds so I don't have to enter them every time I configure a milling operation?

    Yes...

    Re: Feed and cutter speed determination process

    If you plan to do your feedrates in the CAM software using inches per minute, this is the way to go. Enter your IPM when setting up the tool and it will get adjusted to IPS in post.

    I've heard...

    I think Shopbot is the only machine I've run across that uses IPS (inches per second). This isn't the first time I've helped a shopbot user figure out how to deal with this somewhat unique approach,...

    No matter how you set up the tool in Bobcad or any other cam system, you are only going to get a baseline feed/speed autofilled. You still have to apply judgement for a specific job or material and...

    "Between 2 curves" is probably the most ideal and is part of multi axis as Mike suggests. However, the technique I use for working on round overs with equidistant offset is nearly as good since you...

    As a starting point, you'll want to run at around 50 ipm with 15000 rpms to cut that material with a 1/8 inch router bit. No need for multi passes in depth. Just run full depth, conventional milling,...

    You right click at the top of the CAM tree where you put your machine definition in. Sorry, no picture to help, but that will probably give you a good idea where to look.

    That's about what I was figuring when I made the tool paths, but feeds and speeds would be different than my example file.

    I have some techniques for 3d round overs which is a bit more involved to...

    Re: Considering buying BCC V.28

    Your evidence? I'm sure that it is priced too high to justify for a toy for the average home tinkerer. What kind of business plan would it be for Bobcad to price products for that market without...

    Re: V27 3 axis Pro radius toolpath question

    The tool change would probably take as long as the spiral entry anyways, even with an auto-toolchanger, so I'd guess that it would come out about a wash if you're using a 1/2" end mill like I did. If...

    Tormachmaster, the bottom line is that Bobcad is more what we are saying it is than what you are saying it is, both in capability and price vs. value. You may note in the video that there are more...
