AutoZero Touch Plate

(49 customer reviews)




The AutoZero Touch Plate is Siencis revolutionary CNC touch plate design that allows for automatic zero-setting with both straight and irregularly shaped bits (v-bits, ball nose, and tapered) in all X, Y, and Z directions for a fully streamlined probing experience:

  • Skips the process of measuring or assuming the tool size before probing
  • No more need to probe with a straight edged bit to find zero before starting a 3D contour or v-carve
  • Corner cutout allows tool to go to zero to confirm successful probing

Unlike most conventional touch plates, the AutoZeros unique chamfered-edge geometry, symmetry, and tall walls means it can automatically measure and calculate the size and position of the bit you’re using very accurately. Plus, with our gSender control software users can run all functions through pre-built settings to have a seamless zeroing experience without having to mess around with custom macros.

  • Special nickel coating allows for higher surface conductivity to improve touch-off sensitivity
  • Each set comes with a 5ft cable with a strong neodymium magnet and gold plated 5mm ECS5 jack for easy connections to two spots on the touch plate
  • Guaranteed compatibility for the LongMill CNC and likely compatible with other CNC routers with 2-wire, NO probe connections (like Shapeoko, 3018, etc.)
  • Works seamlessly out-of-the-box with the gSender CNC control software
  • Macros and documentation available for other senders too like CNCjs, LinuxCNC, Buildbotics, UGS, and more…
  • Currently set up for Front, Left corner probing only – support for other options coming to gSender soon

    Good quality. Since I am using it for Mach3, I had to wright my own script, but now it works great

    Zero is off by a half inch x and y just starts running away I can’t find anything in G Sender to help fix it

    After re-reading the instructions; I’m in a much better spot with the touch plate.

    This touch plate is a must have for complete accuracy. I got it and thought it might be too cumbersome to get out and wire it up every time do I thought I’d try the paper method.
    Boy, was I wrong. This touch plate saves time for getting the right depth and is better than jogging up and down to see where you are.

    Huge game changer for making projects. Automatic zero-setting of v-bits is a great plus to my cnc experience.

    Does not work at all. I’ve damaged 3 bits trying to use it. Machine does not know where it is….ever.

    This is the first time I have ever used a touch plate. It is so much easier than zeroing all the axis by sight. The touch plate is well made, sturdy, and works very well with the gsender program.

    I use Mach3 and cannot generate or find a suitable code that works so it sits on the shelf.
