An easy example of this would be putting your hand on the cutting truck and preventing it from moving during an operation. I would certainly like to see one set up specifically for cutting wings and learn how they work, how they get the wire temp just right, and how the angled speed compensation is made for tapered/swept wings between the root chord and tip ends. Description of Issue A Z-axis stall is caused when the difference between the commanded distance becomes much more than the actual distance over the allotted time interval. I've never seen a commercial CNC foam cutter in-person. You also have to vary the speed at an angle (moving a little faster over the longer root chord template) so the wire exits the foam in a straight line at exactly the same time from both templates at the trailing edge of the wing. After the machine asks for and calibrates the bit it will jog to the starting corner of the project. Start a project with a simple raster carving on it. The stall happens even when the bit is removed prior to carving. Too slow - the wire melts divots/lines in the foam.too fast, you introduce distortion into the wing contour. Random X, Y, or Z - Axis Stall Causes Cause 1: The random stall is happening because of an intermittent voltage from the power supply. If you've done this yourself, you know if it's a tapered and/or swept wing, it's a bit tricky to get the "feel" for drawing the wire over the templates (and through the foam) at the right speed. and a homemade footswitch with a transformer from Radio Shack providing the voltage to the wire.Ĭonventional "old-school" was make plywood templates (polished, smooth edges) for the root chord and tip, affix them to each end of a foam block and draw the wire through the foam whilst resting the wire on the two end templates and regulating the heat of the wire (in real-time while pulling the wire) using the footswitch on/off. I made my own hot wire cutter using aluminum square tubing, springs, wires, screws, etc. I've manually cut a lot of foam wings for my scratch-built RC models - but that has been over 20 years ago. So I was looking for a short cut with Vectric software. I intend to manipulate the wire assembly to create tapers and such like.

I may have to go to other software but most of it is for 4 axis foam cutting machines. I am trying to add a hot wire to my gantry to make aeroplane wings.
