G30 and deployprobe.g

Th0mpy

Hey everyone! I am working out some macros to deploy and retract an optical z-probe.

To deploy you move the X axis all the way to the left side and to retract you move all the way to the right side. Not too exotic.

In the deployprobe.g i have the following:

G60 S0					;Store current location into first memory slot (to be used for return)
G1 X0 Y10				;Move to the location to deploy the probe 
G1 X0 Y0 Z0 R0			        ;Return to probing point

...and retractprobe.g:

G1 X150 Y10			        ;Move nozzle to retract probe
G1 X0 Y0 Z0 R0				;Move to origin location

This works well, if I move to an arbitrary point and issue a G30. It moves to extend the probe, probes the spot, returns the probe, and moves back to the original location.

What does NOT work is if I issue a command G30 Xnnn Ynnn. I cannot seem to figure out how to use deployprobe AND a G30 command which contains coordinates.

Any ideas?

You could have a M401 command to deploy before the G30 X Y command.

Not sure why it wouldn't deploy automatically though. What firmware version?

Sorry, I should clarify just a little more.

It works, in that, the probe deploys but it will return to the origin that I defined via G60 and probe, NOT the G30 coordinates that I specified.

I just updated so I'm running 3.4

Thanks for the clarification. That's something @dc42 would have to answer on the expected behavior. I've never seen that done before.

Unless that has changed very recently using G30 like that ignores the X and Y parameters.

I have made a request in the past to implement that capability.
