Any Suggestion for correction ?

Hello Everyone!

I have a duet3d driven cartesian printer which worked superfine with high quality prints using stepper motor.
Recently i switched to servo motor (JMC IHSV57 integrated AC servo motor). I have some problems driving the head due to the parameters.

Can someone help me with the duet parameters in M569 command with the above graph ?

currently i use: M569 P7 S0 R1 T2.5:2.5:7:0

The motor moves smoothly but the position feedback is high and the overall movement of the head is not normal. It always tries to correct the position and if i give another command for movement, the motor stops because of driver overload as the previous correction of position is not completed yet.

Has anyone used these motors with duet before ?
Thanks for the help.

Cheers,
Phani

Thank you for the reply.

Is the Fan pin capable of supplying 25v output ?
I tried to search in documentation but could not find any point regarding this.

Hello Everyone,

Just an amateur question. Is it possible to drive an external tool, power high or low by 25v from the duet board ?

Can we use the stepper motor drivers as a normal pin with the help of M42 commands. I know there is a possibility with expansion pin out but i have already used expansion header to drive motors. So i dont have the leverage of using GPIO pins.

But do we have any other pins available on the board that i can turn on and off by sending commands to drive an external device (a cylinder for extruder extension).

Can i use Fan1 PWM pin ?

Thank you for the help.

I tried and it did not work.

I got a new TFT panel display same one and the sd card works fine. So i think its the problem with sd card port in the previous panel.

Thanks for the swift response and support!

No. I did not use any of them. I have a duet Ethernet and expansion header for the drivers. Thats it.

"Cannot initialise SD card1 : card is unusable"

Both 4 way cable and ribbon cable are connected. I double checked the connections, they are as per the documentation.

The length is also less than 250 mm because i read that maximum of 400 mm can only be used.

I think the panel due is not able to read or detect the memory card. I ran the firmware diagnostics also and it reports only one memory card i.e the one in duet.

And the panel due throws an error "Error: 1 accessing SD card" . I tried with different memory cards but it still shows the same error.

yeah. I have used the ribbon cable and connected as per the documentation.
From the panel due 'connect SD' to the duet 'Connect SD'.

Is the panel due i7 compatible with duet Ethernet 1.0 electronics and firmware version 1.19 ?
I tried with new board and 2.04 firmware too but it was not successful.

Thanks for the reply @dc42 .

Maybe a bit of miscommunication, but its more about understanding the fault than about the warranty.

I dont understand the problem with panel Due right now. Its a I7 brand new one directly from duet3d UK website.

But the panel due is not able to read the micro sd card. What could be the possible reason ? Am i missing any connection ? i think there is nothing much from user end because its all straight forward, just connecting the two way wire and power pins.

Panel due is not able to read the sd card. I have done all the connections as per the duet documentation and used the two way wire.

I ordered duet wifi, panel due i7 and expansion header all together. But now i find that only the expansion header seems to work good. Initially duet wifi extruder driver failed and then later the Z probe pin on duet and now panel due seems to be giving trouble.

When i try to work with external sd card it shows only one thing.

"Error: 1 accessing SD card"

Even in DWC i am not able to access the SD card. - "Cannot initialise SD card1 : card is unusable"
What could be the possible problem ?

I was a happy customer of duet with good experience from my last two boards. Being a programmer myself i respect the amount of work being put in to make such a good product. But this particular order seems to be ruining.

Maybe it can be with the resistor because i was not aware of this change of electronics. As the new board is a month old and the other board is around 8 months old.

I have ordered two new boards. So i shall try and figure out with the new board, if it persists.

Yes. I have followed that page and made the connections similarly. The signal is driven to ground and enable port. There is a resistor that pulls down the signal. I found the problem to be with the duet board because of two reasons.

1. The E0 driver was not working and always giving me an current error on DWC and had to change the driver with Y driver.

2. The same machine and software setup works perfectly fine with another duet board, but with this board it produces wrong measurements.

Can i claim for a return or exchange for this faulty board ?

After struggling a lot.

I decided to change the board with my old one. With same settings and same equipment, now i get perfect values.

I think the problem is with duet board, the z probe pin might me floating more than required.

I have reverted back the firmware to an olden working version. But it dint make any difference.

In DWC the older board shows voltage value as 24.5 and the new one shows 24V . Is this difference of any significance ?

Sensor - https://autosen.com/en/Position-Sensors/Inductive-sensors/Inductive-sensor-High-Resistance-Class-IP69K-AI039

The sensor is powered externally by 24 v and the output and ground are connected to a relay. Output of relay is connected to z probe in port of duet and ground to ground.

Thank you for the response.

I changed the parameter and tried it but doesnt seem to solve the problem. The Z probe value on DWC changes rapidly from 0 to 1000. G30 S-1 command is returning measurements in the range of 0.79 to 1.4 mm for the same place. its almost double.

I tried connecting the same setup with my old board and the Z probe measurements are varying from 0 to 400.

So the setup seems to be correct but the measurements returned by the probe are wrong.

i measured the actual distance, it is 1 mm but the z probe returns 1.5. I think 0.5 mm is a huge difference.

Can the problem be with any update ?

Hello,

I have been using duet products for the last 1 year and have built 2 large 3d printers that work with duet electronics. I Have used Duet Ethernet, WiFi and expansion headers for delta and core xy printers which produce amazing prints.

For a new Cartesian printer with duet wifi board the motor drives, extruders everything work fine.

But i am facing a strange problem with Z probe and after a lot of unsuccessful search on forums, posting it here.

I have an inductive Z probe which detects the metal object and also works good during the static and dynamic test. I have done G30 S-1, G29 bed probing, G32 S1 calibration which have all worked as expected.

But later i found out that the Z measurements returned by the probe are wrong because the analog values being produced seem to be of very short variations. In my previous machines i can see the Z probe values in DWC differ from 0 to 500 as the bed approaches near and the average values returned by G30 S-1 are constant for a set of 5 measurements.

But with the new wifi board, the sensor measurements differ only between 958 and 1000 on DWC. The Z probe measurements also vary with a constant pattern. they either increase by 0.5 or decrease for a set of 5 to 10 measurements at the same place on bed.
If my first G30 s-1 returns 1 mm, after 10 measurements it returns 2.5 or 3 mm which is clearly wrong.

The voltage reading shown on DWC is 24V and probe value range from 960 to 1000.
I have tested the sensor and the electronics with my previous board and it works fine.

I feel the problem is either with a firmware update that i am not aware of or somewhere in my settings i am missing something.

; Endstops
M574 X2 Y2 Z2 S1 ; Set active low endstops at high ends

; Z-Probe
M558 P1 H10 F80 T10000 ; Set Z probe type and the dive height + speeds
G31 P930 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X50:1100 Y50:1000 S100 ; Define mesh grid

Any suggestions or possible solutions would be of great help.

@dc42 and team - you people have been doing great, i have always found answers to my problems on the forums.
