      Can I use probe XY coordinates using G30 command without P parameter? If I want to do a single G30 at probe position X150 Y150 how do I do this with the G30 command?

      Right now I do this:
      G1 X150 X175 ; Move nozzle to X150 Y175
      G30 ; Probe at probe position X150 Y150 (G31 X0 Y-25)

      I am thinking if we have different tools the G31 can be different and how can the G30 should still probe in the same place? Is it possible to ask for G30 X# Y# so it takes G31 into consideration rather than having to do this math in the G1 command...?

      Is it possible to ask for a probe at a specified probe position without a P parameter?

      In my bed.g I already do G30 P0, P1 and P2 and after this I want another Z homing probing in the middle of the bed at X150 Y150 but if I put G30 X150 Y150 it does not move to this point

      bed.g:
      G28 ; home
      M401 deploy Z probe ;(omit if using bltouch)
      G30 P0 X0 Y0 Z-99999 ; probe near a leadscrew
      G30 P1 X300 Y0 Z-99999 ; probe near a leadscrew
      G30 P2 X150 Y260 Z-99999 S3 ; probe near a leadscrew and calibrate 3 motors
      M402 retract probe ;(omit if using bltouch)

      G1 X150 X175 ; Move nozzle to X150 Y175
      G30 ; Probe at probe position X150 Y150 (G31 X0 Y-25)
      G1 X150 Y150 ; Move nozzle to center of bed

        While it would seem to make sense to allow that it doesn't work. I have asked a couple of times for it to be made to work that way but so far no changes.

        To probe a single point you have to use a G1 to position then the single G30.
