Is there a way to make it work???????
Have tried running bed leveling 60 times so far nothing works, including manualy adjusting the height map.
Nozzle NEVER goes to Z print height,
Image of head mid print, gap between print head and Height map is accurate to height map.
Print head just hovers over most of the bed only going to print height in the corners.
What am i missing?
@Snippy
From tip to nozzle tip in Z is 2mm
From Nozzle tip to probe in X is 45mm
G31 P500 X45 Y0 Z2
Oh lord, G30 S-1
Stopped at height 4.062 mm
Anything between 1.080mm to 4.062mm On Z0 Midle Platform
After
Calibrate the Z probe trigger height
Make sure the dynamic test is successful (Z probe stops when it senses the bed) before doing this.
Cancel any currently active mesh compensation with M561
Use the X and Y jog buttons to position the nozzle over the centre of the bed
Jog the nozzle down until it is just touching the bed or just gripping a sheet of paper. If the firmware doesn't let you jog it down far enough, send M564 S0 to disable axis limits.
Once you have the nozzle touching the bed, send command G92 Z0 to tell the firmware that the head is at Z=0
Jog the head up by 5 to 10mm
Send command G30 S-1. The nozzle will descend or the bed rise until the probe triggers and the Z height at which the probe stopped will be reported in the console. If you are using a nozzle-contact Z probe, the trigger height will be slightly negative. For any other type of Z probe where the probe triggers before the nozzle contacts the bed, it will be positive.
Repeat from step 5 two or three times to make sure that the trigger height is consistent.
In Duet Web Control, go to Settings -> System Editor and edit the config.g file. Set the Z parameter in the G31 command to the trigger height that was reported. Save the file.
Open config-override.g and check that there are no G31 commands in it. If you find any, delete those lines and save the file.
To apply the new trigger height, restart the Duet by sending M999 or pressing Emergency Stop.
@gloomyandy
2.285 was a mistake did not Home Z, It is now-1.170 mm Mid Z0
So are you still having to babystep by -1mm?
Yes
Does the G30 in the middle of the bed now work?
Yes
What does G30 s-1 return if you run it in the centre of the bed?
G30 s-1
-1.170 mm Mid Z0
-1.080 mm X0 Y0 Z0
what is going on at the left hand side of your bed?
G31 P500 X45 Y0 Z2, Probe cant reatch, too lazy to tweak settings.
Got The bed leveling to ''work''

It still does nothing to compensate, when printing.
When printing i need to manualy babystep ~-1mm for print to stick

What is going on?
@jay_s_uk
There is no Q value, tried 500, no effect, 15000 fan works from 85% on dwc to 99% on fan
@jay_s_uk
Fixed it, now its at 0 or 7500rmp.
aint there suposed to be a Q value on M950 to controll the fan curve?

Only fan connected to the duet is the print cooling

Print cooling fan is conected to the duet, out4
Other fans are hooked to the psu directly.
I need to controll the fan connected to out4, ofc i cant controll stuff that is directly conected to psu.
@jay_s_uk

Print cooling fan runs at full blast allways
Slider tells me that its on 0% yet it goes at ~7000rpm and its rated closer to 6000rpm

Lol thanks, allso it was homing in the wrong direction
M569 P0.1 S1 D3 V2000 ; driver 0.1 goes forwards (Z axis)
M569 P0.2 S1 D3 V2000 ; driver 0.2 goes forwards (Z axis)
M569 P0.3 S1 D3 V2000 ; driver 0.3 goes backwards (X axis)
M569 P0.4 S1 D3 V2000 ; driver 0.4 goes backwards (Y axis)
So S1 to S0
