how do i run Calibrate the Z probe trigger height now without G92 Z0 ?

Is this right now ? (I still godt warnings when i rung G29 mesh)
Which warnings?

Measure your probe trigger height and XY offset as described in that link and then re-create your heightmap.

Z-probe is re calibratet now, and it is now about 0.1-0.15 mm from nozzle to bed. do you think it is to close ?
x is -52 mm and y is -6 mm is that wrong ?
Z is now homing at the mittle of the bed now, and very slow, do i have to change homeall igain?

Z0 should be as close to the bed as possible, so you can adjust the G31 Z value as needed. If you're still 0.1 too far away, add 0.1 to your G31 Z value.
x is -52 mm and y is -6 mm is that wrong ?
That all depends on how you measured it. x-52 and y-6 would be 52mm to the left and 6mm in front of the nozzle. Is that correct?
Z is now homing at the mittle of the bed now, and very slow, do i have to change homeall igain?
The speed of Z probe homing is controlled by M558 F in config.g. It's up to you to decide how fast it should go and still provide accurate results.
If you want to do a fast pass and thena. slower pass you can change your z homing section in homeall and homez to be
M558 A1 F600 G30 M558 A5 F60 G30That will prone the bed once at 10mm/s and then again more slowly for better accuracy at 1mm/s up to 5 times.

The nozzle have to hit the plate with out any air space?
X nozzle 110---- 161.7 Probe mid = 51.7 mm
Y Nozzle 110---- 115.9 probe mid. = 5.9 mm
homeall does it have to be in the middle off bed ?
my x and y is set to 0 and 0, and then it goes slowly to the middel and find z.
just make this one with no warnings, but it still says invalid heightmap after restart
g29
9 points probed, min error -0.010, max error 0.072, mean 0.031, deviation 0.028

Well Z0 should be just touching the bed. That way your slicer first layer height is correct. There are many ways to fudge it to make it work, but accurate layer height and accurate extrusion amount should be the goal I think and will provide good first layer results. Having too high a gap and then over extruding also works, but less elegant.

Y Nozzle 110---- 115.9 probe mid. = 5.9 mmI don't know what this means.

Yes you should try and position the probe as close to the center of the bed as possible. with a few mm anyway.
Can you try deleting the heightmap.csv file from the system tab and re-run G29.
Can you send M122 and M98 P"config.g" and post the results? Would like to know what firmware and DWC version you are using.
-
ok, i don't get it shut touch the bed, read somewhere i has to be a papir like 0.2 away from the bed.
it means, if i move x(nozzle) 51.7 mm from 110mm. I'm in the middel og the probe. I'm not sure about i has to be 51.7 or -51.7.
Delete the file and run nes G29 still the same.
-
-
Can you check the machine specific and general tabs and see what the DWC version is? It should match your firmware 3.3 beta2

Ender 3, with E3d v6 hotend and duet wifi.
I don't not wich thermistor or probe, but i think my probe is pnp 5v.
How do i activate heightmap in plugins?
After the change we had made, my probe did not stop when i place som metal under it, when my Z i going down to zero.
-
I think you're going to need to update your version of DWC to match the beta firmware you're using.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3beta2/DuetWebControl-SD-3.3b2.zip
See if that resolves the invalid heightmap error.
-
that was my fault, now I get heightmap
shut my probe stop when I place some metal when it go down from 250-0 z ?
when I'm trying to print, the dimension does not fit the size I curl slicer, what do I have to calibrate to get the right dimensions ?

Are your steps per mm correct? Does commanding 10mm of movement result in 10mm of actual movement?

@phaedrux
so long so goodI was printing the 20 mm cube.
X= 20.16
Y= 20.12
Z= 19.89how do i fine tune this to get closer to 20.00 mm ?
Is there any good finger rules for extruder speed ?
-
@kosmic First print something larger and see if it's off by the same amount or if it scales with the size of the object. Also print a few objects at different points on the bed to see if it changes with bed position.
You can either fine tune your steps per mm value or use scale compensation.

-
I will try to print 1 pcs more and then I will fine tune it.
Is there a way to test my z-probe?
I can see when my z is on 0, the light is going off on my probe sensor, but I does not stop if I place som metal in front of my sensor.
-
-
I already have done that. but I'm not sure about to check it
if I put in M401 I'm not really sure what that will do ?
I also have trouble with extruder calibration, when it is perfekt and I print a little thing, and after that check about 100mm then it is not 100 mm anymore, do you have any idea why it changes ?
-
If i do this: Send command G30 to do a single Z probe. This will deploy the probe (if applicable) and start the head descending or the bed rising.
Hold a suitable surface below the print head to trigger the Z probe. The probe should trigger and the Z movement should stop.my probe lights switch to off, but i does not stop on the way down to zero.
