help with conditions in variable g-code

arhi

I have this:

  G1 X110 Y-100 Z5 F9000
  M400
  G31 P{sensors.probes[0].value[0] + 8}
  G30 P4 X110 Y-100 Z-9999
  if result != 0
    echo "ERROR P4"
    continue
  echo "DONE P4"

so nothing special, go, probe, if successful print done, if not print error ... simple enough but .. output:

4/10/2020, 12:30:58 PM 	Error: Z probe already triggered at start of probing move
DONE P4

So G30 produced Error, RRF knows there's an error and yet the "result" is 0 ?! like the probing went ok ? (3.01RC6)

What am I doing wrong?

@arhi said in help with conditions in variable g-code:

So G30 produced Error

What error did it report?

arhi

@dc42 you see the error just before the DONE:

Error: Z probe already triggered at start of probing move

I would say that the firmware, having sensed that the probe is already triggered is (correctly) bailing out of the procedure to head off any possible damage,

arhi

@OwenD that is ok, the movement behavior is ok, but the return value is 0 and 0 means "ok", not "error"

It's a bug, which will be fixed in 3.01-RC7. Thanks for reporting it.

arhi

Good, I'm not going crazy then

arhi

@dc42 btw it returns zero in event of other error too (not triggered after a while)

arhi

Error: Probe points P0 to P3 must be in clockwise order starting near minimum X and Y, and P4 must be near the centre

this error does not return 0 (after doing G30 P24 X110 Y100 Z-9999 S0 all the other ones were without S parameter)
