"Search Fail" after Tool Check

[nandkishork59]

I have been able to experiment with toolcheck and subsequent cycle start for searching and resuming the current block from its beginning. Have seen this working well on two controllers already.

However the current controller is giving an alarm 332 - Search Failed - Run/Search was unable to find the re-quested G-code line.

This alarm is new to me. Program structure enclosed below.

The only issue I see is that, since the whole program runs in G91 incremental mode, the results (where will the axes be when you get to line __) is totally dependent on where the axes happen to be sitting when you start the job.

If Resume did consent to run the job, it wouldn't give you the right results unless you were careful to jog all the axes back to exactly where they were sitting when you started the job the first time.

Try programming in absolute (G90) coordinates, and set a suitable part zero location before you begin running.

Tks for a very clear comment on Absolute....
One more and primary issue was that of customized M7 and M8 ....... search bypass first line was missed.....
tks again
