    Hi Mike
    Have a look at the images to remove the Foam shaping cuts
    DevWingFoam-Blocks1

    For the spar use the ventral option as the images show
    Ventral-1
    ventral-2

    Video review and demonstation of the 5-axis CNC Foam Cut controller from Hobbild - devCnc Foam - Links
    .
    Guys
    Here is my review and demonstration of the 5 axis "CNC Foam Cut" controller from Hobbild using a 32-bit Arduino Due. It's very impressive and works fantastic. The hot wire control is excellent.
    Have a look and I'll be glad to answer any questions

    Hi Jeff
    Sorry, I set the first link to private. It should be fine now. The first video in the playlist is this one which may be more useful https://youtu.be/YuCkEB2kIkM

    Hi Jeff
    Profili is quite old now and you may be better using DevWing Foam 2. I have some tutorials on my Youtube channel for Profili and DevWing Foam2. The Profili one is quite old now and my video production is a bit better now so I'll link you to them both
    Profili 2 is here https://www.youtube.com/playlist?list=PLZz...6nxWVhnfdRag8R0
    DevWing Foam 2 is here https://www.youtube.com/playlist?list=PLZz...5QBYLYJopn2hBHF
    Hope it helps

    Speed issue with a 4axis arduino ramps 1.4 - devCnc Foam - General
    .
    2.5 Amps NEMA 17 are too much for DRV8825 drivers. Check the specs here www.pololu.com/product/2133/specs
    It recommends 1.5 Amps continuous and 2.2 max.

    Have you set the current on the drivers to match your stepper motors. what stepper motors and drivers are you using?

    Cutting Project Issue - devWing Foam - CNC hot wire foam cutting of wings
    .
    Hi
    You could try in the cutting strategy option 5 Cutting Direction "trailing Edge at the Home Side"
    That way it will exit at the trailing edge and hopefully not leave a mark.

    I have mine set that way.

    Thank you.
    I'm working on Part 3 now which will show the foam cutter making the wing parts. Going to use DevCNC Foam which I've just switched over to. I have limit switches working now which are useful for foam cutters.
    It's taking a little longer than I expect to get the video made due to some family issues with my wife's elderly parents.

    Hi
    I have just uploaded a new video tutorial for the recently released DevWing Foam 2. The first video Part 1 covers the design phase and the new features in DevWing Foam 2. It's still good for the previous release.
    Part 2 will show how to create the Cutting Projects and some exports and will be released as soon as I can. Part 3 and 4 will show how I cut the parts out and the maiden flight. https://youtu.be/pjx6_OrfhVQ

    Hi Stefano
    I'm a bit puzzled why I have the boxes at the front and rear of the airfoil in the cutting job. I've attaced some picture. It's a simple clark-y airfoil with a 3mm ligthening hole. Am I doing something wrong.

    Thanks
