  • Pressure foot recommendations for use


    Hello,
    Hope y'all are well. I recently got this pressure foot.

    https://www.aliexpress.us/item/2255800283705469.html

    In my head, I saw those ball bearings tipping already-cut pieces upwards and creating an unsafe situation. So I took some plastic and made a bottom that was more like what you see here.

    This weekend I hope to try the project again that I mention in this thread.

    I'm going to try using these bits.

    Any tips y'all might have? Workholding? Setting z? I'm doing all this in hopes of finding a process that works so that when I see a project that is best suited to a laser, I can tackle it with a good cnc method.

    many thanks

    Not familiar with a pressure foot. Can you explain what it is or how it works?
    NM... I did some research and I understand but it doesn't seem like a good solution for small parts.

      I ended up making my own pressure foot out of some delin I had around. It slides nice over the material.

        I made a short video of my pressure foot to explain what it is and how it works.

        Many thanks for any ideas.

        cheers

          That's a really great looking pressure foot. Nice job!

          Do you have any links to the specific model for your spindle?

            Thanks. It's the 4 foot, 75mm one on the link above. Cheers.

              I had a thread on here about cutting with a pressure foot.

                  I would think that the spindle and servo motors would have to all work harder to overcome the pressure and increased friction. I don't think the Camaster engineers built that much addition overhead into their products. You would have to shorten the life of the motors and increase wear on gears etc. I believe machines using the pressure foot were sold with it and therefore have upgraded motors etc. I go back to my days as a teenager who knew nothing about mechanical engineering but increased my 56 Chev horsepower to the point where I blew up transmissions, drivelines and rear ends. It taught me that if you change any mechanical part or add power than there are consequences. IMHO.

                    The pressure foot take very little to move you can set it so it just barely rides on the material but it keeps it from chattering. I use it all the time on thin stuff.
