@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?
-
@T3P3Tony
external driver: Motion king stepper motor drive model no. 2L415Byes we have tested with stock RRF.
-
@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

@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 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 T5:5:10:10And similar for any other external driver.

@droftarts , @dc42 , @T3P3Tony
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 ?
***What can be the possible causes for such behaviour?***bolded text

here is my invoice conforming on my original board purchase.
kindly tell me how to proceed, as none of the board is working well & I am confident about the config declaration of motors.
I have also observed that whenever Yaxis gets this extra pulses due to Z move, after that on homing Y axis, its displays values like -0.6 or -0.0 depending upon its position.Please respond at the earliest here, as I have a customer to respond to & I am stuck with the board isssue.

@R006 said in Duet 2Wifi Board: 3 Z-Axis configuration create problem:
Your config:
M350 Z16 E16 I1 ; configure microstepping with interpolation M92 X160.00 Y160.00 Z2133.33 E932.00 ; set steps per mm ;change as per machine M566 X720.00 Y720.00 Z300.00 E600.00 ; set maximum instantaneous speed changes/jerk (mm/min) M203 X8400.00 Y8400.00 Z420.00 E8400.00 ; set maximum speeds (mm/min) M201 X3000.00 Y3000.00 Z30.00 E250.00 ; set accelerations (mm/s^2) ;M-curr M906 X2200 Y2200 Z1600 E800 I30 ; set motor currents (mA) and motor idle factor in per cent I think the problem is EMF when the motors start and stop, caused by the high jerk setting and the high step rate on the Z axis.
Your Z has 16x microstepping with 2133.33 steps per mm, jerk is 300mm/min (5mm/s), acceleration is 30mm/s^2 and top speed is 420mm/min (7mm/s) (it was 1800mm/min or 30mm/s in your first config.g). Any move will start at 5mm/s, and (if my maths is correct) it takes 0.066s and 0.4mm to get to 7mm/s. At 5mm/s, the step rate is 10.666kHz, at 7mm/s it is 14.9kHz. So it's not really accelerating, more just starting at full speed!
I checked using the specification from MotionKing for your motor https://www.motionking.com/Products/Hybrid_Stepper_Motors/2-phase/17H2A_Stepper_Motor_42mm_1.8degree.htm and the RepRapFirmware EMF calculator https://www.reprapfirmware.org/emf.html, and when running I think the axis should be okay, even at 12V, and should be okay up to around 840mm/min (14mm/s). This doesn't calculate problems when starting and stopping, though.
At what point in the Z move does the step on Y occur? If it is at the start or, more likely, end of the move, I think it's likely the high jerk is causing a voltage spike. You said you saw a single pulse/spike signal, but not when.
Try reducing jerk. Start with
M566 Z6(6mm/min, or 0.1mm/s), which is a more normal figure for an axis with a high step rate. If that works without causing a move in Y, try increasing it if you need more performance. While the motor may be able to use high jerk with no load, once in the machine and under load, I would expect that jerk would need to be reduced to avoid skipping steps at the beginning of the move.Further questions:
What voltage PSU are you using?
Are you using the same PSU for the Duet and external stepper drivers?
If you are using different PSUs, have you connected the negative terminals of the two PSUs together, so there is a common ground?Ian

@R006 said in Duet 2Wifi Board: 3 Z-Axis configuration create problem:
;SKEW
M556 Y1.1 S50.0@dc42 just pointed out to me that you have this line in config.g, and is likely the source of the problem. It wasn't visible in the first config.g you posted. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m556-axis-skew-compensation
The X, Y and Z figures are the number of millimeters of the short side of the triangle that represents how out of true a pair of axes is. The X figure is the error between X and Y, the Y figure is the error between Y and Z, and the Z figure is the error between X and Z. Positive values indicate that the angle between the axis pair is obtuse, negative acute.
The Y value is the skew in YZ. So Z moves will cause a movement in Y. Comment this line out.
