I wrote the attached Macro's to emulate this behavior on my "UCCNC" router.
The functionality is duplicated by using BOTH a mobile plate (with an X/Y centering hole) and a fixed plate. The mobile plate establishes the initial workspace XYZ zero and then the fixed plate is used to determine (and support) a relative offset for ongoing bit changes. The bits are still changed by hand, but no manual re-zeroing is required.
I found a mobile plate with an X/Y zero'ing hole (like Bitzero). The "XYZ Touch Probe Plus" is functionally similar to the Carbide3D Bitzero tool in that it also utilizes an X/Y zero'ing hole: https://www.amazon.com/gp/product/B08CY6NT1M
Pretty much any fixed touch plate will work, you just have to securely fix it to a known location on the worktable. I'm using a laser cut acrylic fixture screwed onto my work plate to hold a pretty common (and cheap) touch plate: https://www.amazon.com/Pieces-Setting-Milling-Engraving-Machine/dp/B08THHMB3Z
For optimum flexibility, I have both of these plates wired (2-wire) into my UCCNC controller in parallel with both probe clips/magnets having the same polarity. (That way I have the option to use either clip without having to swap them on the collet/chuck).
* If you decide to use these macros, you will want to be sure to configure UCCNC to enable M6 macro processing on the settings page (as the default is to "do nothing").
You will also want to be sure your design software post processor supports the Tool Change for UCCNC machines. I have also included a couple of Vectric VCarve post processors I modified to enable this ability. (Its just the addition of a couple of lines for ToolChange support). Although this is labeled as "ATC" support, it is not intended to support a TRUE automatic tool change. Using this M6 macro: It just stops the spindle, asks you to manually change the bit, and then proceeds to establish the new Z-Zero for the new bit. (Maybe I should have designated it "MTC"?) Note also, for Vectric VCarve, you will want to select the option to "save all toolpaths to a single file".

Two macros are provided:
M20031.txt: This is the probing macro which is used to initially establish the workspace XYZ and then also store the Z-Offset for the fixed plate (in C-Axis DRO). You run this after clamping your material, homing your machine, and before starting any job. I named it "M20031.txt" so a user defined button can easily be established to perform the initial probing. (A companion PNG file is also enclosed to use as the button image) Although an "M31" macro is traditionally used to establish Tool Length, I didn't want to displace the dedicated "M31.txt" macro provided with UCCNC (as this is NOT intended to be automatically called). Since our initial probing macro is always run as a manual operation, I thought it was better to be able to just dedicate it to a user-defined button.
Custom M20031 PROBING MACRO
- Code: Select all
// Custom M20031 PROBING MACRO
// Simulates Carbide Motion (Nomad, Shapeko) BITZERO Probing Function (X, Y, Z)
// Requires Both a Mobile Plate (For initial M31 Workspace X, Y, Z) and a Fixed Plate (to support ongoing automatic Zeroing in the Z axis after M6 tool changes)
// * Mobile Plate: An OpenBuilds XYZ Touch Probe Plus (with XY Hole) is used to simulate the Carbide3D BitZero functionality
// * Fixed Plate: Any standard Touch Plate may be affixed to the router bed
// * UCCNC must be specifically configured (in Settings) to run an M6 Macro (default setting = do nothing)
// * The design software post processor for the machine must be configured to support tool changes (a "UCCNC ATC" vectric post processor is also provided)
// The machine must be Homed prior to this activity
// The operator should use a cylindrical touch bit probe in the chuck (not a router bit) for best accuracy
// The operator should manually position the touch bit probe down into the approximate center of the XY Hole of the mobile plate before running this operation
// This macro will first run the X/Y probe inside the mobile plate XY Hole, then lift and reposition to perform a Z probe on the mobile plate
// The Y-Axis probe will run twice for increased accuracy after the approximate center is found (ie: Y probe, X probe, second Y probe)
// This macro will then transition to the location of the fixed plate to calculate the height difference between the Workspace and Fixed plates
// The Z Offset difference between the workspace and fixed plate is stored/maintained in the C-Axis DRO.
// The companion M6 macro is required to retrieve the C-Axis DRO and support the Fixed Plate and automatic Workspace Z Zeroing during tool changes

M6.txt / M20006.txt (basically the same): This is the actual Tool Change Macro.

Custom M20006 TOOL CHANGE MACRO for testing (Tool Check Disabled)
- Code: Select all
// Custom M6 Manual TOOL CHANGE MACRO
// Simulates Carbide Motion (Nomad, Shapeko) BITZERO Probing Function (X, Y, Z)
// Requires Both a Mobile Plate (For initial M31 Workspace X, Y, Z) and a Fixed Plate (to support ongoing automatic Zeroing in the Z axis after M6 tool changes)
// * Mobile Plate: An OpenBuilds XYZ Touch Probe Plus (with XY Hole) is used to simulate the Carbide3D BitZero functionality
// * Fixed Plate: Any standard Touch Plate may be affixed to the router bed
// * UCCNC must be specifically configured (in Settings) to run an M6 Macro (default setting = do nothing)
// * The design software post processor for the machine must be configured to support tool changes (a "UCCNC ATC" vectric post processor is also provided)
// The machine must be Homed prior to this activity
// The macro will position the spindle at the desired location for a manual tool change
// The macro will then transition to the fixed plate to Z-Probe the new router bit and update the Workspace Z Zero.
// The Z Offset difference between the fixed plate and workspace Zero is stored/maintained in the C-Axis DRO.

Basic operation is as follows:
1. Edit the data fields at the beginning of each macro to reflect the specifics of your machine. (Specifically - but not limited to - the XY location of your fixed plate, and the thickness of your mobile plate).
2. Affix your material to the work surface
3. Home your machine (It is important that your machine coord Z-Zero be at the topmost of your Z travel: Machine coord Z=0 is "SafeZ")
4. Put a cylindrical touch bit probe (possibly even a blunt nail, pop rivet, etc) in your collet/chuck for best accuracy (not a splined router bit)
5. Position the XYZ touch plate over the front left corner of your work piece
6. Manually position the tip of the touch bit probe down into the approximate center of the X/Y zero hole of your touch plate. The tip of the touch bit should be below the surface of the touch plate but not actually touching the surface of the work material.
7. Run the M20031 macro. It should move as follows:
- Probe back and forth in the Y-Axis (to find approximate X center)
- Probe back and forth in the X-Axis (to find Y Center)
- Probe back and forth in the Y-Axis (once again for improved X center accuracy)
- Lift up and move over the top of the mobile plate
- Probe the Z height of the mobile plate (at this point we have workspace X/Y/Z zero)
- Lift up and move over the top of the fixed plate
- Probe the Z height of the fixed plate (at this point we now have a reference distance for the z-offset between fixed & mobile plates)
- Save the Z-Offset value into the C-Axis DRO for later retrieval by the M6 Macro.
8. Start your job and (assuming all is configured properly), every time the gcode asks for a tool change (M6):
- The spindle should stop
- The spindle will move to the designated tool change location
- A tool change will be requested (manually change it)
- The bit will be moved over the location of the fixed plate
- A new Z height for the new bit will be probed using the fixed plate
- A new workspace Z-Zero will be automatically re-established using the value stored in the C-Axis DRO
Essentially,
- You only need to do an XYZ probe (M20031) once before starting each job
- Your machine should stop and request a manual bit change (M6) each time it is necessary
- You will NOT have to manually re-zero your Z-Axis after each tool change
OBVIOUSLY, you should test run these macros by hand BEFORE you actually use them in a job. Make sure all YOUR machine settings are set correctly and the movement is always safe and reliable. This is YOUR responsibility!
Note: These macros use subroutine functions. This eliminates mountains of repetitive code and makes the macros much easier to read, test, and modify.
