@Alex9779 I hear you, but I have a hard time understanding what is going on. Sry. Though, 2 things. You have Z_RAISE_BETWEEN_PROBINGS
set which changes MBL in a way I am not familiar with (meaning I have not investigated how or what that does, but I think I can imagine what it is supposed to do). Then X_MIN_POS
looks strange, shouldn't really matter but it looks off, but maybe your endstop is placed outside the bed like that?
Z_RAISE_BETWEEN_PROBINGS
is what it was set to when the setting appeared, I just changed Z_RAISE_PROBE_DEPLOY_STOW
because my probe does not need clearance when deployed, it is fixed...
X_MIN_POS
is ok, my endstop is off the bed and that is the position where the nozzle is when the endstop is hit compared to 0,0 of the bed...
So you need more details?
Oh BTW I think I tried to set Z_RAISE_BETWEEN_PROBINGS
to 0 but without any effect on what happens, the bed rests at Z=5 after homing and the leveling sequence behaves the same...
MBL doesn't use the probe, it is more of a manual process. Nothing is deployed or stowed.
With the endstops being outside of the bed one might need to manually modify the "inset" and how that is added. Right now it is uniform front/back, left/right. But it seems for your use case a longer inset for the "left" side (same side as the X endstop) could be good.
Z behaviour sounds very strange.
Do you have a "probe" configured?
any of these enabled? FIX_MOUNTED_PROBE Z_PROBE_ALLEN_KEY HAS_Z_SERVO_ENDSTOP Z_PROBE_SLED
I am using the exact position setting in adv for mesh bed leveling. The only problem I have is the Z...
When the stow is set to the default value of 15 the bed moves much more down when homing... And also when doing the manual leveling sequence...
I have FIX_MOUNTED_PROBE
activated...
Hmmm...could be that causes G28 to go into this part
https://github.com/MarlinFirmware/Marlin/blob/RCBugFix/Marlin/Marlin_main.cpp#L2834
Which confuses MBL.
Note that MBL "calls" G28 a couple of times.
I recommend to disable the probe if that is possible. MBL is currently a manual process via the LCD (or G-codes if you lack a display) @Roxy-3D is working on adding auto-mesh probing feature, and more.
Ok I am going to try that and report...
See the Probing the bed with the display part here https://github.com/epatel/Marlin/blob/75f9fb50c4002f6d4ba0345f5594cbac1fab1fa6/Documentation/MeshBedLeveling.md#probing-the-bed-with-the-display
Ok I disabled FIXED_MOUNTED_PROBE
and Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
.
It is working again... So as I assumed it was a config problem...
Thanks for clearing it up, it seems I don't need the probe settings, though the probe offset are taken into account for the safe Z homing positions. I could set them all to 0 and just set safe Z homing to where the nozzle should be, couldn't I?
Great it works again. For the other parts, I am not sure, nothing I know how it works, never used :-S
Ok no problem... TYVM!
did you manage to get any of the auto bed-levelling working without the fixed probe? I just see "Auto Bed Leveling requires a probe! Define a Z Servo, Z_PROBE_ALLEN_KE..........'

I am trying to get the RCBugFix of today but I can't get it working anymore since the new probe options in the config. The problem is that after homing the bed is moved to Z=5. That is ok but when I start the mesh bed levelling the machine homes and rests at Z=5. Then I click to start and the machine does the Z hop move to the first position, undoes the Z hop but doesn't move to Z=0 instead goes back to Z=5. Z=5 is not yet 5mm away from the nozzle but about 7mm and the correct is limited to 4mm so I can't get the bed to the nozzle.
Do I have to change something in my config?
