problèmes duet 3 mini5+ coreXY

Hell I have the impression that the printer thinks to be a Cartesian printer yet in the config it is marked

Phaedrux

Are you getting any errors when you try to command the motor that doesn't work?

Which motor/driver isn't working?

no I have no error message when I execute the command
and it is motor for X that does not work

Phaedrux

So if driver3/X motor isn't working, can you swap X and Y and change the driver mapping in config.g as well and retest? Does the problem follow the motor, or stay with the driver?

foukouda

@phaedrux suddenly I did what you ask me and I stink noticed that it is always the engine designed as the X engine that has problems and I can certify that all my engines are well connected and that all my drivers are working correctly

M350 X256 Y256 Z256:256 E64 I0 ; configure microstepping without interpolation
M92 X2560.00 Y2560.00 Z12800.00:12800.00 E409.00 ; set steps per mm

Using x256 microstepping for all axis is not recommended because it can exceed the capabilities of the CPU to keep up with step generation. Best to use x16 with interpolation.

Do you mean it's working correctly now?

@phaedrux hello. It's been two weeks since I try anything and everything. and I can confirm that the problem comes from the programming and not from the wiring or the mechanical side (motor, driver, ext belt)

for more precision
when I run the G91 command
G1 H2 X10 F3000 this one runs as it should.
but not the command
G91
G1 H2 X10 F3000
and it does the same as in the video that I stink sent

foukouda

@foukouda suddenly I would like to ask you if you can make me a customized program I think you are the best for that

(if you don't mind) thank you very much for taking the time to help me

Those are the same commands...

It describes what you should do based on how the motors respond to the commands. Have you followed this yet?

foukouda

@phaedrux already sorry I made a mistake in the second order it is not (G91
G1 H2 X10 F3000)
but (G91
G1 H2 Y10 F3000)
it is the motor called Y which does not work constantly.

and yes I followed what you gave me 3 weeks ago.

I will specify when I execute (G91
G1 H2 X10 F3000) this one is executed normally and in the right direction, i.e. + Y + X

when I execute the command (G91
G1 H2 Y10 F3000) the "bug" command and this one makes a loud noise and seems to want to go in a direction except that it seems to be blocked by something (like in the video I posted)

@foukouda I can't really tell what's happening in the video. It looks like you are clicking Home X? It sounds like the motors are trying to move very fast. Have you tried testing the motors disconnected from the machine? Have you checked that the motor phases are connected correctly? See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Using_the_internal_drivers and https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Identifying_the_stepper_motor_phases

@foukouda Did you address these questions?

Did you update the firmware to 3.3?

foukouda

@phaedrux
I remade a video in clear and precise to help you in my problem.
I also still looked at the polarity of all my motors with a multimeter and everything is good (I have not yet managed to install version 3.3 but I will do it in the evening

@foukouda

So based on your video, you send

G91
G1 H2 X10 and the head moves diagonally in the -X and +Y direction (assuming that -x moves to the left, +x to the right, -y to the front, +y to the back)

From the motor movement testing wiki it says

If it moves towards +X and -Y, or towards -X and +Y, then either turn the power off and swap the X and Y motor connections, or use M584 in config.g to swap the X and Y motor drivers over.

So swap your X and Y motor connectors.

This also brings up the question of how your printer is oriented. Where is the "front" and where is the "back"? Ultimately it's arbitrary, but it's something that needs to be determined first so that we can establish directional behaviour for left/right/front/back. From the video it looks to me like your printer is "backwards", but again, that's arbitrary. You need to decide what makes sense to you.

The directions in the motor testing page assume that you have a right handed coordinate system where -x moves to the left, +x moves to the right, -y moves to the front, +y moves to the back. This is to match the coordinate system used by CAD software and slicers so that your models don't come out mirrored or rotated.

This also dictates how the endstops are configured, because it needs to be told if the endstop is at the low end or negative side, or the high end or positive side of travel. And the homing moves need to move the print head in the correct positive or negative direction to hit the endstop.

Now we come to the last part of the video with the G1 H2 Y10 move and the sound it's making. It almost sounds like a belt slipping or binding causing the motor to stall. Or perhaps a broken wire causing one phase to be disconnected, but if that were the case we should see error messages.

Can you try that move again with the belts removed from the motors? Do the motors turn smoothly then or does it still make noise?
Where is the noise coming from exactly?
Do either motors get very hot to the touch?
Do you have a spare motor to test with?

@phaedrux Find !!!!!

there was a construction error in the connector between the cables and the Duet which made that one of the two phases was not powered

so it's good now all my engines are working correctly

but I must now make the BLtouch and my heated bed work

thank you very much for your help and sorry for the inconvenience
