Duet 2Wifi Board: 3 Z-Axis configuration create problem

R006

Hello,

We are using duet2 wifi board and we add 3 motor for Z-axis as per image

Problem: When we move Z axis motor, Automatically Y Axis motor rotate slightly due to noise on the channel

We have configured Z axis motor in different combination as listed below

We have add z axis motor on 50 pin expansion connector
E_5 for Z1
E_6 for Z2
E_7 for Z3

Observation: Same as above, When we move Z axis motor, Automatically Y Axis motor rotate slightly due to noise as observed on DSO also.

We moved z axis motor on 50 pin expansion connector
On board Z driver for Z1
E_5 for Z2
E_6 for Z3

Observation: Same as above, When we move Z axis motor, Automatically Y Axis motor rotate slightly due to noise . (Single pulse/spike signal causes the Y motor to rotate).

We also tried with Z axis 3 motor connected to Z , Y and X axis on board connection
Z axis - Z1
Y axis - Z2
X axis - Z3
E_5 for X axis
E_6 for Y axis

In this case , When we move Z axis motor, There is no noise in any motor.
But In this case X and Y axis didn't move at all and we didn't find any signal at step or dir pin with respect to GND.

When we run Z homing There is no noise in Y axis.
But When we use move command we observe noise in Y Axis motor.

We also tried to change to a different duet 2 wifi board, the result is same.

@dc42 ,@Phaedrux
Please give us some solution for above problem. Is it a problem with the board?
And why do the XY motors don't run with E_5 & E_6 channels while Z does?

Phaedrux

Are your motor wires running alongside each other?
What are the motor models?

R006

@Phaedrux

Here is your answer inline,
Are your motor wires running alongside each other? - NO
We have used shielded wire and it's separate from each other.

Motor model : Motion king stepper motor 17H2A9425 2.5 Amp 1.8 degree

Phaedrux

Please share your config.g and homing files as well as the output of sending M122 and M98 P"config.g" in the gcode console.

Can you provide a photo of your wiring setup?

R006

@Phaedrux

Can you provide a photo of your wiring setup?
Actually we have set table top setup for testing purpose.
We have connect motor to board and display only.
and still we get noise in Y axis motor.

T3P3Tony

@R006 so what external drivers are you using on the expansion header for the motors you are connecting there.

Also a note you are using custom RRF, have you tested with stock RRF?

R006

@T3P3Tony
external driver: Motion king stepper motor drive model no. 2L415B

yes we have tested with stock RRF.

droftarts

@R006 is it a genuine Duet3D board? Which version of RRF did you test with? Try 3.4.6 https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.6

Ian

R006

@droftarts
yes it is.
i tried with 3.4.4 & 3.4.6 RRF version standard RRF.

I even tried to configure 2 motor in Z with same configuration, but again on Z movement, Y axis gets some random pulse.

Tried with 3 different duet 2 WIFI boards and observed this problem repeatedly, when the Z travel more then 5-10 mm then Y motor rotates intermittently, due to some random pulse signals on it,

Could you please try at your end, by configuring 3 different Z motors, oneY and one X, run 4 stepper motors with just the board? (temporarily just mark Z0, Y0 X0 using G92 & move Z axis by 5mm, then Y axis gets some pulse? IF you hold the motor shaft, you might feel it. You can also monitor the Y axis pins on DSO to see this.

NOTE: External driver was only used for Extruder. I was using onboard drivers for axes.

R006

@T3P3Tony @Phaedrux @dc42
I am waiting for your response.

gloomyandy

@R006 It might help if you post a picture of the board showing how you have the motors connected.

@R006 Di you have a higher resolution version, it is hard to see what you have connected to the board in that picture.

@R006 in your config.g, you haven’t specified any timing for your external drivers, set by M569 Txx:xx:xx:xx parameter. I think this may be causing a problem, as it will be using the default timing of ‘fast’, which is only suitable for the on-board drivers. The high frequency of these steps, and the high step rate you have set for Z (M92 Z2133.33) may be causing the interference. Try:

M569 P5 S1 T5:5:10:10

And similar for any other external driver.

hey,
i tried as per your suggestion but problem remains same. Please find detailed observations as per trials:

with onboard drivers connected for all axes:

I have 4 boards, and all of them with latest or old software have same behaviour.
Somehow on while moving Z, Y axis gets some pulse.
If i interchange the driver of X& Y, from P0 , P1 respectively to P1, P0, even then the noise appears only on the Y channel.
The problem is some intermittent pulse that generates only on Y channel when declared. If i make P0 & P1 as X, then noise does not appear.
It appears only if the Zmove is > 5mm .
This noise does not generate when we HOME Z, but move Z at the same homing speed, the problem appears.

with XY via external driver:
7) When we use SPI-> external driver-> with suggested timing parameters, the probelms still exists.

I have tried many things, Can you please check this once in the boards with you ? Somewhere a pulse is generated for the Y axis only when z moves.

Is there anywhere in code where i can look for the problem ?
