Issue with G38.5

I am quite proficient with build-install-clone commands and have the ability to simultaneously have and use all the versions under investigation on a single HDD. Currently installed and used alternately are
2.8.4 and 4.19. 195-rtai-amd64 - works almost flawlessly, except for a known (and already fixed in 2.9.7) bug (I easily ported it to 2.9.4, as well as matrixkin from 2.10 to 2.9.7 and 2.9.4), so I have to do without G38.5
2.9.4 with kernels 254 and 290 - they are unable to work due to a bug for multi-engine configurations, see forum.linuxcnc.org/9-installing-linuxcnc...-2-9?start=60#339123
2.9.7 - of course, I don't like userspace, but I am ready to use it for G38 tasks. It is unable to work due to this, forum.linuxcnc.org/38-general-linuxcnc-q...bing?start=10#338958 , bug

I realised that several posts later, and could have saved myself a great deal of typing.

I will try to look into this, probably with a simulated probe input for simplicity.

Have you tried inserting an explicit queue-buster between the successive probe moves? (I almost feel that we should have a specific code for that, maybe related to M70)
If you insert M66 P0 L0 between the probe moves then the queue might be cleared as a side effect.
Doing some offline research about this I found wiki.linuxcnc.org/cgi-bin/wiki.pl?QueuebustersRevisited which whilst not immediately relevant does discuss some of the issues around the motion queue.

If you insert M66 P0 L0 between the probe moves then the queue might be cleared as a side effect.

Great news, thanks for the idea. I'll check it out tomorrow with version 2.9.7 and let you know the results.

Verified - adding the code M66 P0 L0 around all G38 did not eliminate the error. 2.9.7
