qtvismach, a axis toolpath

I don't have a repository, but I can send the files.
Actually, it's just two modified files: `primitives.py` and `qt_vismach.py`.

A new class for 3D stock has been added to `primitives.py`. It is suitable for XYZ machines but will not work with a rotary axis.
The sampling frequency is independent of the Vismach refresh rate (currently set to 50ms).
It automatically retrieves tool geometry from Vismach.

The toolpath handling in `qt_vismach.py` has been heavily optimized. It can now manage a much longer toolpath history without placing an excessive load on the CPU—effectively handling unlimited paths for typical use cases.
A small menu for selecting certain settings has also been added, with room for further options. It places almost no load on the CPU when the machine is idle.

I also created a test machine to verify the new stock functionality; although creating the solid is nearly identical to the existing methods, just one extra line of code is required. This machine does not define specific dimensions or positioning; it exists solely for testing the stock.

Looks fantastic in pics! haven't trued it yet.

I tried this out. Excellent job.
I did not if I move the origin the material stock does not move, even if I rebuild the material. Does this happen for you?

Material movement won't work in `machine_test`; it is just a simple configuration for testing purposes. In my configuration, I write the following code in the custom qtdragon handler file:

if (hal.component_exists("vismach")) == False:
    c = hal.component("vismach")
    c.newpin("mat_X_min", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Y_min", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Z_min", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_X", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Y", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Z", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_X_max", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Y_max", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("mat_Z_max", hal.HAL_FLOAT, hal.HAL_IN)
    c.newpin("hide-chuck", hal.HAL_BIT, hal.HAL_IN)
    c.newpin("hide-konik", hal.HAL_BIT, hal.HAL_IN)
    c.newpin("os3", hal.HAL_BIT, hal.HAL_IN)
    c.ready()

def update_gcode_properties(props):
    if props != None:
        print ("update update_gcode")

        s = linuxcnc.stat()
        s.poll()

        print("MatPoz        :", s.g5x_offset[2])   

        property_names = {
                'x': "X bounds:",'x_zero_rxy':'X @ Zero Rotation:',
                'y': "Y bounds:",'y_zero_rxy':'Y @ Zero Rotation:',
                'z': "Z bounds:",'z_zero_rxy':'Z @ Zero Rotation:',
                'a': "A bounds:", 'b': "B bounds:",
            }
        #print (props)
        X_poz_min = float((props.get('x_zero_rxy').split())[0])
        Y_poz_min = float((props.get('y_zero_rxy').split())[0])
        Z_poz_min = float((props.get('z_zero_rxy').split())[0])
        X_poz = float((props.get('x_zero_rxy').split())[4])
        Y_poz = float((props.get('y_zero_rxy').split())[4])

        X_poz_max = float((props.get('x_zero_rxy').split())[2])
        Y_poz_max = float((props.get('y_zero_rxy').split())[2])
#        Z_poz_max = float((props.get('z_zero_rxy').split())[2])
        Z_poz_max = (s.g5x_offset[2])

        # G20 -> G21
        if props.get('gcode_units') == 'in':
            X_poz_min *= 25.4
            X_poz *= 25.4
            X_poz_max *= 25.4

            Y_poz_min *= 25.4
            Y_poz *= 25.4
            Y_poz_max *= 25.4

            Z_poz_min *= 25.4
            Z_poz *= 25.4

        print ("mat_X_min =", X_poz_min,"    mat_X_max =", X_poz_max,"    mat_X =", X_poz)
        print ("mat_Y_min =", Y_poz_min,"    mat_Y_max =", Y_poz_max,"    mat_Y =", Y_poz)
        print ("mat_Z_min =", Z_poz_min,"    mat_Z_max =", Z_poz_max,"    mat_Z =", Z_poz)
        hal.set_p("vismach.mat_X_min", X_poz_min)
        hal.set_p("vismach.mat_X", X_poz)
        hal.set_p("vismach.mat_X_max", X_poz_max)
        hal.set_p("vismach.mat_Y_min", Y_poz_min)
        hal.set_p("vismach.mat_Y", Y_poz)
        hal.set_p("vismach.mat_Y_max", Y_poz_max)
        hal.set_p("vismach.mat_Z_min", Z_poz_min)
        hal.set_p("vismach.mat_Z", Z_poz )
        hal.set_p("vismach.mat_Z_max", Z_poz_max)

So, it writes the dimension positions to the HAL pins, and then, in the handler file, it reads the material dimensions from those pins (just like in that commented-out section that constructs the material).

This function is located in the qtdragon handler file because it isn't called within the vismach file itself when launching vismach in a standalone window; however, this approach allows for launching a second (or subsequent) vismach window without issues (e.g., to test with different parameters).

I'm constantly making tweaks—like saving the machined material to an STL file.
If you have any interesting ideas, let me know.
