only z motor tries to work
-
sounds like you may have wired the other motors incorrectly, ref https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Identifying_the_stepper_motor_phases to check the motor wiring.
(turn off the power before making any changes to the motor wiring!)
-
Check the phases and wiring .
If you try to home any of the axis you will get a fault if the Z axis is wrong because it lifts the bed ( Z ) before it moves X or Y axis.
-
Many thanks for your reply!
I've checked the wiring and all are connected right!
It's specially weird, that only one z motor from 4 make this sounds and vibrates.
I hope you have another idea!
-
@Inno-3D said in only z motor tries to work:
I hope you have another idea!
the other idea is that the drivers might be damaged, so I was hoping the one idea was enough.
Run
M122before and after asking the motors to move and post the results and one of the big shots will probably be able to say something about whats up -
Ok I've did it!

@Inno-3D Please post your config.g file, and perhaps post a picture of how your Duet and Duex are wired. The result shows that driver 2 has stalled (the
SG min/max 0/1023), and that (I think) nothing is connected to driver 5 and 6. I'd guess the Z motor on 2 is wired incorrectly. Or, if you have only one motor plugged in on Z, do you have the jumpers on the second Z output pins? See below:
For example when I would like to home x, the z motor tries to home.
That's quite normal; in the homing files, the Z usually lifts the nozzle (or drops the bed, depending on your machine) 5mm to avoid it hitting the bed, before homing X or Y.

Driver 2 has 2 ports, but they are wired in series, so you cannot use it for 4 separate motors as it sounds like you are trying to do.
Your photo shows you have some spare drivers left, so move the second motor on driver 2 to its own driver and replace it with the jumpers as indicated by @droftarts and then remap the Z axis to use 4 drivers in M584
-
@Inno-3D You have Z defined as drivers 2, 5 and 6. But, as I expected, you don't have anything connected to drivers 5 and 6 on the Duet. There are two motors connected to driver 8 and 9. And you have two motors on the Z driver. What is the specification of these motors?
Your config.g shows why you're having problems with Z, and probably with your other motors as well. With 5120 steps per mm, and maximum speed of 180mm/m (3mm/s), your Z motors can't move fast enough. Even the accelerations and instantaneous speed changes settings are probably too high to allow the motor to move. Your steps per mm are peculiarly high; are you sure they are correct? What are the motors driving?
Also, in your config.g you have many places where you have defined motor settings for each motor on the axis, eg
M350 X16 Y16:16 Z16:16:16 E16 I1
You can only define each motor on the E axis. For the other axes, only the first setting is used. The rest are ignored, and/or may even cause problems. Use these:M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation M92 X6400.00 Y5120.00 Z5120.00 E420.00 ; set steps per mm M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min) M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min) M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2) M906 X2000 Y2000 Z2000 E800 I30 ; set motor currents (mA) and motor idle factor in per centIan

Many thanks for your response!
@Phaedrux I will test it later when I'am at home.
@droftarts Oh that's my fault, the two motors connected to driver 8 and 9 should be connected to driver 5 and 6. I will change it!
This are brake motors but I defently know, that the brake is open, because i can rotate thim myself.
I know that the motor rated current is 3 amps and the duet 2 wifi only provide 2,4 amps. Is it a problem, when the motor don't get 3 amps?
Oh yes you are right the steps per mm are to high. I actually changed it.
The z motors are driving a leadscrew with a picht from 5 mm and they have a gear ratio from 1:1,38. So I have 883,2 steps per mm.
You can only define each motor on the E axis. For the other axes, only the first setting is used. The rest are ignored, and/or may even cause problems. Use these:
Ok! I will use these part and change it at my config file.
-
@Inno-3D the motor specification says these motors have an inductance of 11mH, which is very high. This will limit the speed. See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Inductance
Use the EMF calculator here to work out the maximum speed you can drive these motors: https://www.reprapfirmware.org/
I expect it won’t be very high. In the end, these motors may not be a good choice for this application.Ian
-
@droftarts I have hope I have used the right values. I have this calculated:
Does it mean that the maximum speed is 17.1 mm/s?
-
@Inno-3D can you show the motor settings? Because I’d expect the results to be much lower.
Ian
-
@droftarts here is a photo of the settings
which are hopefully right.
-
@Inno-3D the steps per mm is different from earlier? Which is correct? In reality, what the EMF calculator suggests is usually the absolute maximum. It’s best to set max speed a sensible amount below this.
Ian
-
@droftarts i think that the steps per mm above are correct, because I have used another steps per mm calculator an it said the same one like abobe.
Ok I will test it tomorrow and give feedback
-
@droftarts I changed the steps per mm and I have connected the motors to the right driver. Now It's working better but not corretly.
I tested to home all axis, the the z axis drove a little bit up and than the y axis shortly rotate.
But what is with the x axis? And why does y only shortly rotate? And why doesn't the z axis drive down? Do you know why?
I tested the connection cabel from the x motor and it works
I don't understand it!
Many thanks for your help!!!
-
@Inno-3D said in only z motor tries to work:
And why does y only shortly rotate?
you'd probably need to post your homing files to be able to answer that.
and you have confirmed the endstops are working correctly?
-
@bearer I've tested the endstops. When I put them, I get a signal. So I think, that they are working.
Here are my homin files:
-
@Inno-3D please post current config.g, and M122 after trying to home.
