The AutoZero Touch Plate is Sienci’s revolutionary CNC touch plate that allows for automatic zero-setting in all X, Y and Z directions, with both straight and irregularly shaped bits (v-bits, ball nose and tapered.)

Engineered by our team, the AutoZero allows for a fully streamlined probing experience:

Skip 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 AutoZero’s unique chamfered-edge geometry, symmetry and tall walls allows it to automatically measure and calculate the size and position of the bit you’re using, with extreme accuracy. Plus, when combined 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.

Works great. Isn’t an absolute necessity, but saves time when setting up.

Great product. Part of me thought that this block was over engineered but I’m glad I bought it. It has features I don’t use every day, but knowing I have those features available when I need them is fantastic.

Definitely worth the extra few dollars and a must have with any machine purchase in my opinion.

The auto touch plate using G sender is a wonderful piece of hardware. I mainly use just the Z axis set, but love the way you have to verify the connection before it will zero.

I really like the autozero touch plate. I had one on my other one and was never able to hook it up and use it,
This one was so simple.
