I think in your case the duex would be the best option

Phaedrux

You could setup initially with just the Duet Wifi and it's 5 drivers and get the CoreXY working. Then you can decide after how many motors you would need for your IDEX build. Or are you planning and going straight to the IDEX build?

The Duet Wifi has 5 drivers. The Duex2 has an additional 2 drivers, and the Duex5 has 5 more drivers.

I would plan for 3 Z motors to do auto bed leveling, 2 extruders, and then perhaps up to 4 more motors depending on what your CoreXY IDEX arrangement ends up being.

neetspeed

thank you so much for your help,
yes exactly I'm going to mount everything in corexy, and start to prepare everything for the additional chario.
I have only 2 stepper motor for z, so duet2 wifi 5 motor available, I need the extension duex5 in my opinion as its I would be good to add the 3rd stepper motor on z, and I add my missing extruder for chario idex, and i will be ready for the future i think

merci énormement pour votre aide,
oui exactement je vais tout monter en corexy, et comencer a tout preparer pour la chario suplementaire.
j'ai que 2 moteur pas a pas pour z, alors duet2 wifi 5 moteur disponible, il me faut l'extention duex5 a mon avis comme sa je serai bien pour rajouter le 3 eme moteur pas a pas sur z, et moi rajouter mon extrudeur manquant pour le chario idex, et je serai parer pour l'avenir je pensse

Hello to everybody
well it's going well for now,
the most complicated for me will soon arrive
you gave me strength thank you

salut a vous
bon ça avance bien pour l'instant ,
le plus compliqué pour moi va bientôt arriver
vous m'avez donner la force merci

Hi
good i got my duex5 and everything else i continue my project,
but I have a blockage
it makes me crazy twice I change the bl touch I configure everything,
it comes in it goes out, upon ignition then nothing.
the z burst my 7 inch paneldue,
pff i have more strength
I have more than her to conquer to pass to the additional axis u

salut
bon jai recu ma duex5 et tout le reste je continu mon projet ,
mais la jai un bloquage
ça me rend dingue deux fois je change le bl touch je configure tout ,
il rentre il sort , a l'alumage puis plus rien .
le z ma eclater un paneldue 7 pouce ,
pff j'ai plus de force
il me reste plus que sa de conpliquer pour paser a l'axe u suplementaire

Hi friends
I explain my problem, the bltouch seems to work, it is triggered when the machine is switched on (ignition, up and down)
tests them it responds when I ask it to go up or down,
but when I run home,
xy correctly, but Z rises slightly then descends without ever stopping,
I manually operate the bltouche change nothing even if the sense of motor is not correct it should stop right?
I have an error the Z probe was not triggered at the survey

I don't know what to do I'm lost I keep looking
Thanks for your help

config (2).g

salut les amis
J'explique mon problème, le bltouch semble fonctionner, il se déclenche lorsque la machine est allumée (allumage, haut et bas)
les teste, il répond quand je lui demande de monter ou de descendre,
mais quand je rentre chez moi,
xy correctement, mais Z monte légèrement puis descend sans jamais s'arrêter,
J'utilise manuellement le bltouche ne change rien même si le sens du moteur n'est pas correct il faut s'arrêter non?
J'ai une erreur, la sonde Z n'a pas été déclenchée lors de l'enquête

Je ne sais pas quoi faire, je suis perdu, je continue de chercher
Merci de votre aideconfig (2).g

Phaedrux

Post your homeall as well.

neetspeed

ok merci
homeall.g

Phaedrux

Your config and homeall look ok. It sounds like the white signal wire is not making connection. Check your wiring again. Try re-crimping. Check for breaks.

neetspeed

thank you
you are a champion
I had 2 problem, the engine reverse I suspected,
and malge my tests on the wiring, actually when the chario was moving I had a false contact o white wire

Merci
tu es un champion
J'ai eu 2 problèmes, le moteur inversé je le soupçonnais,
et malge mes tests sur le câblage, en fait quand le chario se déplaçait j'avais un faux contact o un fil blanc

Have you seen this page for corexy commissioning?
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter

neetspeed

Yes thanks
I leaf through them,
everything is fine in the X Y movements,
I had a problem with Z sa seems to be resolved,
I cable everything, I pass the cable chain, included for the U axis carriage
and as soon as everything goes well for core xy I pass to the addition of U,
I have an additional manipulation to indicate u in markforged mode ??
or am I just adding an additional axis?
thank you

Oui merci
Je les feuillette,
tout va bien dans les mouvements X Y,
J'ai eu un problème avec Z sa semble être résolu,
Je câble tout, je passe la chaîne de câbles, incluse pour le chariot de l'axe U
et dès que tout se passe bien pour le noyau xy je passe à l'ajout de U,
J'ai une manipulation supplémentaire pour indiquer u en mode markforged ??
ou est-ce que j'ajoute juste un axe supplémentaire?
Merci

neetspeed

hi friends
everything seems to work, except the Z bed which is difficult to synchronize I try to manage to separate the driver and automatic level correction,
and still no news for the addition of mark forged chario

salut les amis
tout semble fonctionner, sauf le lit Z qui est difficile à synchroniser j'essaye de réussir à séparer le driver et la correction automatique du niveau,
et toujours pas de nouvelles pour l'ajout de marque forgé chario

Have you seen this?

As for the IDEX markforged kinematics I have no idea.

neetspeed

Yes
but I have a problem,
it tells me motor
phase a,
phase b,
disconect and the descent bed instead
to go up
c complicated for i find idex markforged ?? I mounted the motor for the carriage and everything
the host is missing,
I understood that duet supported all the modes
slim
I hope to find I will have to transform everything into a Cartezienne

Oui
Mais j'ai un problème,
ça me dit moteur
phase a,
phase b,
déconnecter et le lit de descente à la place
à monter

c compliqué car je trouve idex markforged ?? J'ai monté le moteur pour le chariot et tout
l'hôte manque,
J'ai compris que le duo supportait tous les modes
svelte
J'espère trouver que je vais devoir tout transformer en cartezienne

How fast are you trying to move the motors?
Has it always done that, or is that new?
How do you have the motors.

Anything is possible, but I'm not aware of anyone who has done it yet. Hopefully will have more details soon.

neetspeed

c good i forgot the jumpers to disconnect the second motor from z
but nothing to do e1 goes in the wrong direction

c bon j'ai oublié les cavaliers pour déconnecter le deuxième moteur de z
mais rien à faire e1 va dans la mauvaise directionut nothing to do e1 goes in the wrong direction

neetspeed

maybe dc42,
I noticed that he had mentioned this in a suget in a subject on the net

peut-être dc42,
J'ai remarqué qu'il avait mentionné cela dans un suget dans un sujet sur le net

neetspeed

for bed correction ç OK g32c ok
I miss details and chario u I just have to configure it becomes complicated

pour la correction du lit ç OK g32c ok
Les détails me manquent et chario je dois juste configurer ça devient compliqué

@neetspeed If E1 is going the wrong way, change direction with M569 P4 'S' parameter.

For the Markforged kinematics, can you post a diagram of your belt layout? You say that it is CoreXY + Markforge U, is that correct? Or do you have two motors for U and V, like a second CoreXY?

If you are running CoreXYUV, use M669 K8. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M669_Set_kinematics_type_and_kinematics_parameters

If you are running CoreXY + Markforge U, you have to work out the transformation matrix. This is how one axis moving affects the others. It's also M669, but with additional parameters for X, Y and U. To do this, you need to work out how each axis moves when the others move. X and Y should be the same as a normal CoreXY, but with an additional value for U. Send M669 to see the current matrix; in CoreXY mode, I get (I have added the comments):

Kinematics is CoreXY, matrix:
1.00 1.00 0 ; This how X, Y and Z motors move when there is a positive X move
1.00 -1.00 0 ; This how X, Y and Z motors move when there is a positive Y move
0 0 1.00 ; This how X, Y and Z motors move when there is a positive Z move

U needs to move when X and Y move. It will probably be something like:

1.00 1.00 0 0 ; This how X, Y, U and Z motors move when there is a positive X move
1.00 -1.00 -1.00 0 ; This how X, Y, U and Z motors move when there is a positive Y move
0 0 1.00 0 ; This how X, Y, U and Z motors move when there is a positive U move
0 0 0 1.00 ; This how X, Y, U and Z motors move when there is a positive Z move

A positive X move shouldn't move the U axis (even though the X and Y motors move). A positive Y move will make the U axis move positively (but may move negatively, so check), so needs -1 to counteract this. A positive U move shouldn't move X or Y. However, this is just a guess! You have the machine in front of you, so should be able to work this out.

This would give an M669 command like:
M669 X1:1:0:0 Y1:-1:-1:0 U0:0:1:0 Z0:0:0:1
Which would replace the one in your config.g.

Seeing a picture of your belt setup would help, but I think this is close.
