Duet3 mini voron gantry level problem

[jamaicarasta]

Hello guys, I'm new here and from Germany. I switched from Klipper to RRF. So far I am very happy that I did. I love it and the panel due 7 inch. But i have a gantry level problem with the duet mini in my voron 2.4 350mm. I have a IR probe to probe Z. With the G32, to measure, it first moves to the middle and then all 4 corners. Then this error message comes up.

Error: Bed calibration : 4 factor calibration requested but only 0 points provided

7 G30 P2 X15 Y315 z-99999
8 G30 P3 X300 X315 z-99999
9 G30 P4 X300 X5 z-99999 S4

How do I continue? I've searched the internet for hours but just can't find the solution. I would be very grateful for tips.

Greetings Marc

@jamaicarasta in all but one probe point you have 2 X axis coordinates, change it too -

@jamaicarasta your probe points to start at 0
So P0, P1, P2 and P3, not P1, P2, P3 and P4

[jamaicarasta]

@jay_s_uk
ok thanks i thought i have to start at p1 because my 4z motors are plugged into 1,2,3,4.
I will Try it in a few Hours when I'm back at the printer.
I'll let you know
It's amazing how quickly you get an answer here.

@jumpedwithbothfeet
where do i have 2 times x? don't quite understand. I gave correct points 4 times in my opinion.
Thanks

[jamaicarasta]

@jay_s_uk
and one more question if i may. it does not go to my specified coordinates exactly. X15 stays at X40 on rehearsal. but if I drive normally with g1 then it drives exactly to x15. only at g32 is it off by 25.

[jay_s_uk]

@jamaicarasta it applies the G31 offsets to that, so if your probe is -25 in X, the nozzle has to be at 40 for the probe to be at 15

[jamaicarasta]

@jay_s_uk
ok i will check that i took a config from the internet from the beginning and maybe the value there is wrong for my probe

[jamaicarasta]

@jay_s_uk
So the error is gone, now I have the next error. is that something in the config file?

@jamaicarasta You need an M671 to set the pivot points of the gantry.
I would probably go with the point where it the belts attach

[jamaicarasta]

@jay_s_uk
ok m671… i forgot it. I read that yesterday. So measure again from the corner of the bed X0 Y0 and enter the minus value there?

[jay_s_uk]

@jamaicarasta yea, each one would typically sit outside the print area. the M671 should be in the order the Z motors are declared

[jamaicarasta]

@jay_s_uk
Ah ok. Xmotor1:motor2:motor3:motor4 Ymotor1:motor2:motor3:motor4
You are my hero
I hope I can ask you a few more questions in the near future. I still have a few things I don't quite understand.

[jamaicarasta]

@jay_s_uk
I measured and found the values. Should I measure the values ​​from the probe points or simply add them to the entire coordinate system? Example X0Y0 as bett end x-55y-25 from bett end to my middle belt. Or measured from the probe coordinates I gave him.

[jay_s_uk]

@jamaicarasta the locations are in relation to X0 Y0

[jamaicarasta]

@jay_s_uk
Ok perfect
it works great now. Is there once enough or should he do it several times before printing. It's a very good probe now, I'm only asking because the red probe that came with it always took 4 rounds or more. I exchanged it because it melted at 285 degrees carbon printing defies cork and polyimide tape...

[jumpedwithbothfeet]

@jamaicarasta you had the X listed twice in each line instead of one X and one Y

6 G30 P1 X15 X5 z-99999

however I suspect @jay_s_uk hit the nail on the head with the probe numbering being the actual issue and flagging up the warning

[jamaicarasta]

@jumpedwithbothfeet
Sorry that was a old file
I don’t saw this. Now is not x and x in one line

[jay_s_uk]

@jumpedwithbothfeet you can get it to run until for so many iterations until a set value is obtained.
we have an example here https://teamgloomy.github.io/useful_macros.html#bedg-file-for-g32 that can ne used with 4 locations as well
