    is it possible to export a drawing from sketchup ?

    There is a free plugin that lets you export an .stl file

    The pro version of sketchup has lots of export options

    Thanks Pavlo I have got an iffy copy to see if it will do what I want if it does then I will buy it.
    M250 I will PM you tomorrow been a bad day here in Hull with the weather and the wife getting stuck at work lol.
    Had another quick look at it tonight I got the immage into a polly line from inkscan and looked at a trial version of CamBam it took the image and it works just to flaming big and no real easy way to resize it.
    I know I am new to all this but bloody hell there has to be a better way to do this or we as a comunity need to look at putting a knowlage base together for people of all skill leavels.
    I know this is an old topic but we need to start saving the how to's of skills that are being lost on the whole I worked in thin plate welding and a little forge stuff and even now the basics are being lost just my rant sorry.
    Just a quick one does anyone know of a how to site for engineering etc to avoid the loss if these skills?

    Also anyone know of some idiot tutorials lol for me? I really want to learn this due to me having two machines sat there waiting to earn me money lol so I hate giving in call me stubbern but I'm sure with a little gental to moderate prodding I can do it. Famous last words hehehe.

    Resizing in CamBam was a bit of a pain but that's been fixed in the latest beta release - what version are you using?

    If you want to post your CamBam file here I'll have a look at it.

    The CamBam site has some tutorial stuff...

    http://www.cambam.info/doc/

    http://www.cambam.info/vids/Introduction/

    There are also some very helpful people on the forum...

    You might find it useful to go through the process of building this with CamBam since it looks like SolidCam uses the same principles (pockets / profiles etc) but I think CamBam is one of the easier CAM programs to use. I know it took me a while to get my head round SolidWorks so I suspect the combination of SolidWorks and SolidCam will be quite daunting.

    trigger.dxf
    trigger1.dxf
    Ok the first is the dxf the next is a .nc so you will need to rename it(I can not seem to get the add files to see the .cb extentions)
    The names of the files is as so
    trigger.cb
    trigger.cb.b1
    these are for the next two files from camba
    Copy of trigger2.txt
    Copy of trigger3.txt
    sorry its so stuffed up new to all this

    P.S thanks for all the help on this I know it would be easy to ask someone else to do it but then I would not learn anything or where I am getting it wrong.

    trigger.cb (the .b1 file is just a backup) looks pretty good - have you tried machining it?

    You could replace the two circles (imported as polylines) with CamBam ones but it should work ok as is.

    The drill MOP needs to be deeper than the material by a couple of mm.

    You might want to put some holding tabs in the profile.

    The triangular pocket won't be too accurate with a 6mm cutter but it's probably only there to save plastic so I wouldn't worry about it.

    The feed rates are very low - 25 for plunge is ok but 200 - 300 (or more depending on your machine) would be better for cutting otherwise the tool will rub and wear quickly. What are you using as a controller? It should allow you to alter the feed rate as you cut so you can start off slowly. It should also show you the tool path so you can check that it's sensible.

    For test runs I often use MDF and a router cutter or an old slot mill. For the very first runs you can just cut in air with your finger on the emergency stop button if you're not too sure about it :)

    You can get a better picture of the part by rotating the view in CamBam (alt + left mouse button by default)

    I've attached a copy of the file that I've had a quick go at to demonstrate some of the above.

    Thank you so much. I have just got half a dozen bars of soap that will go in the vice I have they are bigger than the job so there should be quiet a big outline left round the side. This is the very first thing I have made comp wise to send to the machine.
    I have a denford starmill the small ones that schools used to have. The controler is mach3 I have done a few dry runs with it and so far the code looks good so fingers crossed

    Well this this is my bar of soap lol.
    I did not do the outer profile last night just the inner ones.
    I had a little trouble with the set up of the machine and set the Z too low.
    When done it should look like the black bit of plastic lol I wish
