So Z2 is at X-60.5 and Z4 is at X360.5?
I had a friend who was having a similar problem and it turned out that he had the Z motors wired the opposite of what he thought and thus each leveling pass made it worse.
It wouldn't hurt to double check your printer.
In your M92 command you have Z1600.00:1600. While I doubt this is a problem the correct syntax would just be Z1600 or Z1600.00 if you prefer the trailing zeros.
And just to make sure, Z1600 would be correct for 2mm (lead and pitch) lead screws - is that what you are using?

Yes all of it is correct an i corrected the M92.
Motors are correcly connected and i tried to plug them the other way around, that made things way worse as you and @Nurgelrot described.
But these things did sadly not help.

What did the trick was to reduce the Probingspeeds to this:

M558 P1 R0.5 C"zprobe.in" H5 F600 T50000                                       ; set Z probe type to effector and the dive height + speeds

and to give the steppers a little bit more juice upped the game hier from 1400 to 1600 and upped the drivespeed of the steppers to a max rate of 1600.

Now i finaly have a Mesh Level wich i can trust:

Thanks for all your thougts an the help.
Will mark this thread as solved.

Ok for the next time i will do that.
Should be mentioned in the Wiki.

Hi, had the same question at some point where i was using swithes instead of the stallguard homing.

My approach was to use some kind of IR-Probe style switches witch would spit out an analog signal and would slow down the axis like in the z-Probing movement with davids IR-Probe but only for X and Y.

Dont know i that is possible though.

It is also possible that the switch suffers from the heat. The springs inside are mostly out of metal and the dimensions of these an thus also the springrate changes with temperature slightly. Is the reapeated reading under the same temperature the same?

Hi to you both,

@phaedrux said in And here we go again G29 Bed Mesh leveling going bonkers:

Does your probe require deploying and retracting? If not, remove the M401 and M402 lines.

no it doess not and is now removed.

@phaedrux said in And here we go again G29 Bed Mesh leveling going bonkers:

You should probably also add M561 to the start of your bed.g to clear any compensations, etc before starting.

Ok is added

@phaedrux said in And here we go again G29 Bed Mesh leveling going bonkers:

What happens if you probe the same point over and over with G30 S-1? Does the reported trigger height increase as well?

Is Z16 the stepper driving the lead screw at X-60.5 and Z15 the stepper driving the lead screw at 360.5?

Thanks for leading me to it, the microstepping of 15 was a typo.
Corrected that and tried evrything again, but to no avail. Same problem persists.
And yes first z-motor is at x-60,5 and y 150 end the second at X360.5 and y150.

Hi,
on my second Printer i redid the wirering and tydied some things up.
Flashed the new 3.3 Firmware on the Duet2Wifi and thougt it would be a good idear to redo the Bedleveling since a new heatbet alongside a new Heater and a springsteel plate war installed.

Since then i think i must have do something wrong with the Leveling cause the Mesh process adds to evry probing step some tens of a millimeter.

So the bed looks completly funky and starts at 0.034 and continusly climbs to 2.091mm and that simply cant be true.
It seems if the probe ist constantly adding a specific Value after echt probing.

Looks like some serpentine roads in the Alps

But that is sadly not usable.

I tried a lot in the past days, but i can't figure the hell out what i did wrong.
Would be nice if someone of you could take a look at these files ant determen if i did something catastrophicly wrong :).

By the way i use a Piezo Probe for probing the bed with the Nozzle of the printhead directly.
Firmware 3.3 and Bed is mechanically OK in level

@phaedrux said in Strange highmap problem:

Your homez uses the z endstop to homez. The z min height is -6mm. There's your 6mm offset.

You should use the probe to home z with a G30 before doing the mesh with G29 so that it has an accurate Z0 position that matches the probe offset.

Thx fo the info will try that and report the results but it sounds plausible ;).

Edit: Some 30min later, the Problem is solved, thank you very much.

Hi i have a slight problem adjusting my bed via meshbedleveling. Out of some strange behavior my G29 responds with a highmap some 5 or 6mm too deep. Mean deviation is acceptable, but i don't now if this works for printing in Case of compensating.

Here is a picture of the highmap:

Here is my config:

My Question is, what did i do wrong here?
My printer is a self build toolchanger. Has 4 tools and a build volume of 300mm³.

Thx for the help.

If there are any Boards left, icould use 4 of the.

Ok i think i got it to work.
The toolboard are not working flawlessley.

That was because of the line:

M950 F0 C"121.out2+121.out2.tach" Q25000                                        ; create fan 0 on pin 121.out1 and set its frequency
M106 P0 C"Tool 1 Lüfter" S1 H1 T45  

wich needed to look like this:

M950 F0 C"121.out2+out2.tach" Q25000                                        ; create fan 0 on pin 121.out1 and set its frequency
M106 P0 C"Tool 1 Lüfter" S1 H1 T45  

Now i wil try to repin from 3 to 4 pin Socket on the Board-Fans to look if i can solve that problem there too.

edit on:

Jep that pinning helped thx very much for the Info.

edit off.

If you wish to control them change to: black -> out6

ok will try that, but thats wiered becouse all 3-Pin headers on the normal PC-fans will only fit like that so i have to unpin them is that right?

From the DWC console please execute M98 P"config.g" and report to us any warnings or errors that may appear on the console.

M98 P"config.g"

Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 647C
Warning: Macro file config-override.g not found

looks like there are some errors in it will investigate that

The Q parameter of 25000 is greater than I normally use. Have you tried something like 2500?

also tryed 500 which is the standard value, only switched it to 25000 because i thought pc fans have a PWM frequency of 25000Hz

Thanks
