Within the Tools Tab, you can setup probes and give them names. I have 4 probes. a tool length setter on my RCATC, a wireless probe I use for determining the height of my material, a wired probe which does the same but is smaller than the wireless and finally a 3d touch probe.
On a Manual Tool Setter, you cannot set the probe input. You have to change to auto, and then select a input and finally switch back.
then there's the BLUM routines. which tool does it use? maybe an option to select the tool you want to use with the routines might be a good idea. My wired probe has the edge detecting circle, which could be useful in some BLUM routines, or my 3d probe for others. I'm not sure which
probe they use by default. is is G31, G31.1 etc...

Hi,
A manual tool setter does not have an input for Mach, Manual tool setters are usually some sort of scale. Place the tool setter on the table, jog the tool down to touch it until the dial reads zero or an LED lights up, and press the "Measure Tool Length" button on the Software to record the measurement. If you're using a G31 move to set your tool, you're going to want to use the Auto Tool Setter.
For the BLUM routines, go to Setup and Help → Browse...→ C:\Mach\Subroutines, and select that folder. This will give you a bunch of values. By default the Probe Tool Number is value 99, but this is where you change that value. Really, all the routines work off of your selected tool values, but if you were to use Calibrate Z or Calibrate X and Y, then it would directly change the values for Tool Number 99.. If you use multiple probes, then just set up different tools that have your probe settings and make sure that you're on the correct tool when doing your routine.
BLUM by design uses only the primary probe (G31). If you wanted to use and secondary probe inputs (G31.1, G31.2, G31.3) Then you will need to do some Mach Trickery. The easiest method would be to create a Button on your dashboard to swap your G31 inputs.
