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?

https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors

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.

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

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.

hi guys
thank you ,
I have exactly this kinematics of belt

my corexy
m669
kinematics is CoreXY, matrix:
1.00 1.00 0
1.00 -1.00 0
0 0 1.00

my first chario, stop 9.5 mm before the charion U, which has the same dimensions as x in mirror, finally I suppose

and I'm not M669, I have M667 S1

salut les gars
Merci ,
J'ai exactement cette cinématique de ceinture

mon corexy
m669
la cinématique est CoreXY, matrice:
1,00 1,00 0
1,00 -1,00 0
0 0 1,00

mon premier chario, arrêtez-vous à 9,5 mm avant le charion U, qui a les mêmes dimensions que x dans le miroir, enfin je suppose

et je ne suis pas M669, j'ai M667 S1

That looks correct to me except that the U motor values should come after the Z motor values, not before. If you also put parameter K1 in that command it will be this:

M669 K1 X1:1:0:0 Y1:-1:0:-1 U0:0:0:1 Z0:0:1:0

then it can replace your M667 command.

@neetspeed, in case you didn't notice, I just corrected my previous reply.

I saw the correct version
thank you dc42 really
Y, lost half his speed,
but the movement XY works it is necessary I create the axis U

dc42

Yes you need to create the U axis using the M584 command. https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

neetspeed

speed will recover?

@neetspeed said in Rat rig v-core pro COREXYU:

I don't know why the speed has changed. When you have added the U axis in M584, please post your config.g file.

neetspeed

error G28 I dig
config (3).g

G28 U
Error: Bad command: '' 'Accueil U en haut de l'axe' ''
Error: G0/G1: insufficient axes homed

droftarts

@neetspeed Have you added homing of U to homeall.g, and/or created homeu.g? Or, for now, set the U axis position with G92 U[postition], eg G92 U100.

@neetspeed

These two belts do not look parallel. I think they are for the CoreXY carriage. This will cause the belt to get tighter as the carriage moves left, and will create LOTS of problems. Belt paths MUST be straight, and at 90º. The only place where they don't have to be straight is at the back, where the X and Y belt cross, like your picture earlier:

no c the U belt
temporary for the moment but x goes first and does not bother thanks
