@jbrazio @thinkyhead please take a look at this snippet. In case the probing fails all attempts G26 is used to give control back to the host, all other commands are ignored so that the print doesn't process. This is managed in the parser and is intended to handle hosts that aren't aware of this feature.

We prefer to reserve G26 if possible.

Granted if the intent is to be able to do manual cleaning of the nozzle and continue then the host needs to prevent all G-Code from being sent other than G26, Marlin cannot hold each command it receives in its buffer until it sees a G26, not enough memory; and it shouldn't throw away all other commands if they're not G26 as done here. This only done to handle "unaware" hosts.

Hum you may I've checked and G26 is not defined anywhere. But I assume when we need user intervention we would call stop() right ? To get out of stop() you may use M999 S1.

@jbrazio currently we don't call stop(). The buffer can still get filled when IsStopped() == true. To prevent any host from sending commands into the buffer after probing has failed we throw away all commands other than G26. That's why we handle G26 in the parser. M999 S1 could be used for this purpose as well but since we allocated G26 before this PR and are afraid of having future conflicts with it.

@scalez We've had some discussions recently about the handling of commands ahead of the normal command buffer. I don't know how conclusive they were. But understand that if a host fills up the buffer after issuing G29 (most likely while printing a GCode file) then the G26 command may not be seen until the G29 command exits and the machine resumes accepting commands.

@thinkyhead Currently we're flushing the command buffer when we enter the PROBE_FAIL_PANIC state. So even if the buffer is filled it is cleared and there is plenty of room for G26 to enter the buffer.

I see! So, I'm also wondering why we need a new command or a "special" kind of panic, since we have M999 (and recently added M999 S1 to preserve the rx_buffer). Also, if, as you say, the buffer is flushed then there should be no need to do special handling of G26 outside of the normal command buffer. (We want to minimize calls to strcmp in the gcode parser.)

This should not be altered. The length given is meant to be excessive, so that even if the Z probe is very far away from the bed it will still reach it. We can't use a "point" here because the Z coordinate is not really "known" when probing.

@thinkyhead this movement is still relative to the origin. Therefore, -(Z_MAX_LENGTH + 10) would be a huge negative number that is essentially guaranteed to be outside of the range of the Z axis (Z_MIN_POS to Z_MAX_POS).

MIN_PROBE_PT is set in Configuration.h and could easily be set to any value, including -(Z_MAX_LENGTH + 10) if desired for any reason.

Why exactly do you think the position is lost during probing? set_bed_level_equation_lsq(plane_equation_coefficients) is not called until after probing is completed. Maybe the position isn't well-known if you are using the same mechanism for probing as you are for homing, in which case you can still simply change the value of MIN_PROBE_PT in Configuration.h.

Why exactly do you think the position is lost during probing?

I don't mean to say it's lost, just not accurate or especially meaningful. During probing, the Z position is just a working number for moving up and down, and not necessarily guaranteed to be an accurate reflection of the Z-distance to the bed. At least, that is how I have tended to think of it. But maybe that has changed…?

@thinkyhead I think I see what you mean, when one point successfully probes the current position may not be accurate after the pin is toggled. From our tests this works fine.

In fact, we've even published a commit in our repo that sets the position of an axis when an endstop (not the reference one used for homing) is hit to (float)endstops_trigsteps[_AXIS(AXIS)]/axis_steps_per_unit[_AXIS(AXIS)]. That way, when an endstop is hit the position is kept to the current position on that axis. Take a look at alephobjects@ec71eda to see what I'm talking about.

I see you're trying to keep the Z probe from going more than 2mm below the bed, but as pointed out above, that's not how this works. We don't know where Z is on the first probe, and during probing we don't know if the probe failed because the probe is broken or because it never reached the bed.

@thinkyhead we do know where the probe is before/on the first probe because we know the machine has already found its origin. Unless I'm mistaken, please elaborate.

Yes, on re-bump this might work. But we don't really know that zPosition is accurate. If you only wanted to keep the probe from going more than 2mm below the bed, you could use…
