ZA and ZB connections ?

I second that. Life of the 10mm white steel-reinforced belt was around 3kg of plastic on my CoreXY. However, they are stiffer than the 12mm 2GT belts sold by E3D. Still a good choice if you can use larger bend radii.

Regarding the Z-platform: that does not look too bad to me. Run a mesh calibration, so some movements, run it again, and see what shifted where.

Exécutez un étalonnage du maillage, donc certains mouvements, exécutez-le à nouveau et voyez ce qui a changé où.

I do a G29, at the beginning of all my impressions and the results are each time slightly different?

I no longer use my Bed.g but only G29 in my slicer.

Is there better for bed compensation, advice or a file to share (which I will adapt to my configuration)?
I also think that by dint of changing my configuration, I may have destabilized it with functions that are useless!

[Veti]

post a picture of the g29 result.

[Rudy2A]

@Veti said in ZA and ZB connections ?:

poster une photo du résultat g29.

Typically a great case ...

When we look at the photo of G29, we can see that the right front side of my bed is far too low and the rear left side of my bed is too high!

Even if I try to lay my bed as flat as possible, the test below remains essentially the same ... as if the height map was not taken into account and yet the motors (ZA and E1) are running much differently.

I print a 5 cm strip that goes around my bed 15 cm from its edge to do a test (with this height chart) and strangely the strip is very flattened only behind my bed in the middle. The rest acceptable and adheres to my bed despite the height map.
It’s as if every time my G29 does its job, except in the middle of the rear.

[Veti]

without special instruction G32 will not correct for that missalignment. and it cant to some extend.
get the bed flat first, then continue testing.

i am still waiting for the output of multible G32 commands

Thank you for your involvement, it's very honorable of you ...

what do you mean by "i am still waiting for the output of multible G32 commands"... i didn't understand, sorry (google translator) .

[Rudy2A]

@Veti said in ZA and ZB connections ?:

j'attends toujours la sortie des commandes multibles G32

Is that what you want to talk about?

[DIY-O-Sphere]

Hi Rudy2A,
my experience is, that the Z-axis of the hypercube isn't rigid enough. The frame of the bed bends to much. I would suggest you to improve that fist.
Try to find z-carriages witch connect the beams by plates.

For my modification you will need new bearings. But I have seen similar parts for the standard bearings on thingiverse.
You should also replace the springs by silicon dampers.
After that, the Z-Axis is absolutely reliable. Forget about levelling before every print.
Auto bed leveling can't compensate mechanical weakness.

Regards
Frank

@Rudy2A

Is that what you want to talk about?

yes. that means your bed is so bad that it does not do any adjustment.
you will need to manual get the bed close to a flat area before you can do normal G32 adjustment.

Even with these values (I can not do better ), nothing happens !

I'm starting to get lost because I don't understand something!
If the limits of the correction points must not exceed 0.00 mm, what is the point of making an automatic correction with G32, since the limits being at 0, there will be no automatic correction?

I post my files, if a charitable soul can take a look and correct it would be great!

Thank you !

mon expérience est que l'axe Z de l'hypercube n'est pas assez rigide

Thank you for this advice.

M671 X-10: 240 Y0: 0 S0,5; vis à plomb à gauche (connectées à Z) et à droite (connectées à E1) de l'axe X

duet uses . and not , for decimal, so this command does not work.

M584 X0 Y1 Z2: 4 U4 E3 P3 ; deux moteurs Z connectés aux sorties pilote Z et E1

there should be no spaces in a lot of your commands.
also you should delete the u axis. it is not needed

M207 ; Paramétre de rétraction

thats not a command for the config. it has no parameters.

M558 P1 X0 Z0

bltouch is P9, and this config line is missing a lot of parameters.

G31 P500 Z1.48

you are missing the offset of your probe

[Rudy2A]

@Veti said in ZA and ZB connections ?:

Thank you for being so kind to watch ...

However, I didn’t understand everything.

M671 X-10: 240 Y0: 0 S0,5; vis à plomb à gauche (connectées à Z) et à droite (connectées à E1) de l'axe X

utilisations en duo. et non, pour la décimale, donc cette commande ne fonctionne pas.

S0,5 Is he the problem?

M584 X0 Y1 Z2: 4 U4 E3 P3 ; deux moteurs Z connectés aux sorties pilote Z et E1

il ne devrait pas y avoir d'espace dans beaucoup de vos commandes.
vous devez également supprimer l'axe u. ce n'est pas nécessaire

OK

M207 ; Paramétre de rétraction

OK

ce n'est pas une commande pour la config. il n'a pas de paramètres.

M558 P1 X0 Z0

This is not an order for the mini IR probe?

bltouch est P9, et cette ligne de configuration manque beaucoup de paramètres.

G31 P500 Z1.48

il vous manque le décalage de votre sonde

I do not use BLTouch, but a mini IR probe ... It seems to me that there is no lag? (to check)

[Veti]

@Rudy2A said in ZA and ZB connections ?:

S0,5 Is he the problem?

yes

This is not an order for the mini IR probe?

i assumed you have a bltouch because of this
M307 H3 A-1 C-1 D-1 ; Désactiver le chauffage sur le canal PWM pour le BLTouch

but even the mini ir probe has an offset. without the offset you probing will be wrong

[Rudy2A]

@Veti said in ZA and ZB connections ?:

S0,5 Est-ce le problème?

It’s with people like you that we move forward!

As I start and sometimes I am a little stupid ... if it is not S0.5 what to put, I simply copied from a previously cited example.

For the rest I understood ...

[Veti]

@Rudy2A

you have to write S0.5
you wrote S0,5

notice , and . duet does not use , for decimal representation.

[Rudy2A]

@Veti said in ZA and ZB connections ?:

vous devez écrire S0.5
vous avez écrit S0,5

Ok ... frankly, I was far from that mistake . Thank you !

[Rudy2A]

Hello, thanks to the members of this forum and more particularly to Veti.

I solved my problem and my current tests are very good. I only have a few small adjustments left and everything will be on top!

I still have a question ... I would like to get the best out of G32 and G29 in my impressions. How do you go about your settings?

You make a G32 in your slicer and you included in your Bed.g G29 or G29S1 file or else, you put G32 and G29 (S1) or vice versa in your slicer or do you use another method?

I take your advice once again.

[Veti]

if you run G32 then you need to run a G29 and not a G29 S1.

[Rudy2A]

@Veti said in ZA and ZB connections ?:

si vous exécutez G32, vous devez exécuter un G29 et non un G29 S1.

Very good, but in what order? G29 followed by G32 (or vice versa in my slicer or G32 in my slicer and G29 in my Bed.g or other file?

The best solution...
