    Where do you find the "Z Probe Wizard"? I use OpenBuilds Control and have read several post here about it but can't seem to find where it is.

    Hit me up if you need help setting up and X,Y,Z probe macro. You'll need a probe block like the one in the picture.

    When I use "Probe Z0 Wizard", the bitl comes down slow then touches as it is supposed to. That's it. Then it askes if I want to raise bit. I answer yes and the bit raises. Then after disconnecting the probe I use the selection to "Goto Z0 (Work Coord)(G0Zo)". The Z "Bit" goes down as expected, but when I look close it is 1 to 2 mm above the work surface. I thought it should be just touching the work surface? Also is it functioning properly at first by only lowering Z (bit) and just touching the probe and then just stop. Shouldn't it go through a touch, retract, touch again then retract again? Or is that a program (gcode) that has to be written? My main concern is that after using the probe Wizard it doesn't touch the work surface when command given above is executed. I used calipers to measure my probe plate, so I know I've got the thickness entered right in Probe Wizard setup.

    Is your Steps per mm properly calibrated?

    Can grab me a screenshot of your Probe window (with all the values you enter) (Want to run it here with the same just to check) and then a screenshot of the Serial Log tab showing all the probing action

    As requested here is a screenshot of probe setup and probe command, command to retract then commend to go to work zero. I measured the distance from the work surface and the bit and it was .66 to .67mm.

    The wizard is sending all the right commands. So must be something mechanical:

    - loose lead nuts
    - loose motor couplers
    - loose VWheels
    - wiggle the machine and see if you find any backlash

    I went and checked the above and all were secure. I then went into Grbl settings and looked at $102. Mine was set to 188.976 (z, step/mm). I went through the calculation setup and it wanted to setup setting to 200.000 (z, step/mm). That was a little too tight. So I looked at the print out for WorkBee 1010 Grbl Settings from the web site and it shows the setting to at 199.100 (z,stemp/mm). That was the golden sweet spot. Now it is dead on. Thanks for your help. Always learning with your help.

    @sharmstr I would very much like to know how to set this up. Just completed my lead 1010 with black box and would like to setup touch probe for x y and z. Thank you for any help

    Setup a XYZ Touch Probe with a CNC xPro Controller

    At the bottom of the page there are two docs. One that explains the probe code and one that helps you calculate the correct values to put in the code.

    Note: You will need to change 2 things.

    1 - In the code, replace all semi-colons with new lines.
    2 - Add G90 to a new line at the very end.

    Let me know if you have any questions.
