G32 S2...

killrmodz

So, after finally getting my z probe dialed in, i moved forward with autoleveling. All seemed good until it tried to reach the third point. For some reason, it decided to reset before attempting to probe that point. Has anyone ever ran into this. I'm on 92.9. Thanks!

Check in eeprom for coordinates set there. Maybe it is "NaN". Normally it is no problem.

This is what I have... I don't see a NaN. Where esle would I find that entry?

Repetier, so I have it working now. But after probing the 3rd point, it will not go back to home to figure z max. I'm using G32 S2 after running a G28. Any advice?

Repetier

You use G32 S2 only once (which is why you save result to eeprom), so there is no real problem. Without z max probing it would not get correct z height and G28 would not work reliable afterwards. Not sure if we have already improved this in dev version where we now know we had homed z before and now use z difference to compute height.

killrmodz

Ok, so it get's z height based on the z max homing, or g28? If i'm understanding correctly, because that makes sense as to why it will not go to z max after probing.

killrmodz

Sorry that didn't make sense. I mean that is why we home first so when it probes it can established a true z max. Yes?

Repetier

Computing z height is done by homing to z max afterwards, yes. If you homed before it would be possible to omit this step, but not sure if we have implemented this possible solution in dev. The method with z max homing has the advantage of always working even when unhomed.

killrmodz

Ok. So if that's the case if I do a g28 first, then g32 it shouldn't do a z max afterwards? Sorry just got confused... LOL

killrmodz

Because if that is really the case, my g32 command doesn't do a z max after probing... so back to square one.

Repetier

What I said is that it depends on printer type and version you are using. dev version does no homing afterwards older version do if I remember right.

Ok, thank you!
