only z motor tries to work

droftarts

@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 cent

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.

droftarts

@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

Inno 3D

@droftarts I have hope I have used the right values. I have this calculated:

EMF calculator.png

Does it mean that the maximum speed is 17.1 mm/s?

droftarts

@Inno-3D can you show the motor settings? Because I’d expect the results to be much lower.

Ian

Inno 3D

@droftarts here is a photo of the settings
which are hopefully right.

EMF calculator1.png

droftarts

@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

Inno 3D

@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

Inno 3D

@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?

Inno 3D

@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:

homez.g homey.g homex.g homeall.g

droftarts

@Inno-3D please post current config.g, and M122 after trying to home.

Phaedrux

Your config file is for RRF3, but your installed firmware version is only 2.03.

I would suggest you update your firmware.

First you will need to update to 3.0 and then 3.1.1.

First upload this zip file as is to the /sys folder.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip

Then upload this one.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

Then start testing from there.

@Phaedrux well spotted!

@Phaedrux yes you are right!

Now it's working!!!

Many thanks for your help guys I'am so happy that it's working now!
