Hello: I t

I'm trying to update my Duet2wifi card currently using version 3.1.1. I checked that on the website it is recommended to install version 3.2.2 first. I didn't find this version available on Github, so I tried to make a new SD card using version 3.4.1 and was unsuccessful. can anybody help me?

"The location where the firmware files are stored was changed. Versions previous to RRF 3.3 stored them in the ‘0:/sys/’ directory, but from version 3.3 they are stored in the ‘0:/firmware/’ directory. When you upload the version 3.3 files in an older RRF version, they will be stored in the /sys directory. Once RRF 3.3 has been installed, subsequent firmware uploads will cause the /firmware directory to be created, and the firmware files will be stored in there."

@alankilian, @Phaedrux and @dc42. I solved the problem, thanks for yor tips and support.

I discovered the electronic component that was damaged, it was a 47K resistor (R80) of the voltage divider (PWR_FAIL_DET2).

I replaced the resistor with another resistor and my machine returned to normal!

@alankilian said in Attempt to move motors when VIN is not in range:

@Phaedrux Is Vin monitored through one of the POWER_FAIL_DETx inputs?
If so, he could measure the voltage at those components and see if it's strange. It's possible one of the two resistors in the divider are poorly soldered or cracked.

@alankilian , do you refer to components like resistors and capacitors connected to PWR_FAIL_DET2 R80 - 47K, R81 - 4K7 AND C79 - 10nF and PWR_FAIL_DET R15 - 47K, R16 - 4K7 AND C80 10nF?

Attached a figure showing these components in the electronic circuit. 

@Phaedrux I have an oscilloscope but I do not have acces to hot air station to replace the MCU, some components like to resistors or caps no problem to replace.

@Phaedrux said in Attempt to move motors when VIN is not in range:

Checking to see if there is any means of repair short of replacing the MCU.
When and where was the Duet purchased?

Sorry, I don't understand, do you say to replace the MCU or try to repair it without replacing the MCU?

I bought it from a friend in Brazil who referred me to the duet.
Last week I bought a Duet2Wifi clone from Makerbase in China, as I live in Brazil, the pound is very expensive for us, the cost of importing a Duet2 from England is around 364.30 pounds.
Today when I turn on the machine, the voltage shown on the DWC and detected by the board is around 2,60 volts. Yestarday was around 14 volts, but the power supply is stable at 24 volts all the time.
I also checked the 3,3 Volts line on Board, it is ok, I also Checked the 5 volts line and the results are ok.
ADVREF or VDDOUT problems? Or VDDIN or VDDCORE?
It is possible to repair Verfe components or it is necessary change the MCu....
I attached the simulation to buy a new Duet2wifi to Brazil.

HI people. The same problem, today I can not start the machine because the Vin is 9,1 volts, yesterday I printed whith 18 volts...

Anyone can help me?

@hackinistrator said in Attempt to move motors when VIN is not in range:

maybe also try connecting the board to your second 12v supply and see if the readings are also off .

The hotend / bed temps are correct, there is no variation, they remain constant as a function of time.

I changed my 24 volts power supply, and the 12 volts power supply too, the problem persists. Nothing changed.
24,3 Volts on the new 24 volts power supply and around 17 volts on DWC.

@hackinistrator Do you refered to bed thermistor and hot end thermistor? I disconnected both, the same problem, powe suplly 24 volts, DWC show me 17 volts

@hackinistrator said in Attempt to move motors when VIN is not in range:

@Milke i see only 0 to 2 connected to Vref . maybe if one of them is shorted to +24V it effects the reference .

Could you help me identify it on the board? Their number and position?

@hackinistrator Are you referring to thermistors 0 to thermistor 7?

@dc42 I am also confused, because sometimes when I turn on the machine, the voltage shown on the DWC and detected by the board is around 30 volts and sometimes around 14 volts, but the power supply is stable at 24 volts all the time.
I also checked the 3,3 Volts line on Board, it is ok, I also Checked the 5 volts line and the results are ok.
ADVREF or VDDOUT problems? Or VDDIN or VDDCORE?

@Phaedrux said in Attempt to move motors when VIN is not in range:

At what point does it start to show the wrong voltage? As soon as you try to move a motor?

Now the voltage of My Power Supplay is 24 volts checked with multimeter and a voltage display. The DUet Web Contro, show me 13,2 Volts and M122: Error status: 0
MCU temperature: min 37.2, current 39.3, max 39.6
Supply voltage: min 12.2, current 14.1, max 14.6, under voltage events: 0, over voltage events: 0, power good: yes
With low voltage I can move the motors , the voltage do not change in the power supply, I use a 30A/24Volts Power Supply for Duet2Wifi (motors and hot end), for thehot bed I use a separate Power Supply 12Volts/50A, I use separate Mosfets for hot bed and hot end.
I don't know what's going on. Sometimes the voltage is high and the motors do not start, sometimes the voltage is low and I can print to a certain point until the machine suddenly stops.
I tested the reference voltage on inductor L5 and Capacitor C64, the voltage is 3,29 Volts .
I checked the temperarture in Wifi Board and SD Card whith my PIR thermomether 33,1 °C and 33,1° C.

Is it possible that the processor is defective Or could the inductor and capacitor be in trouble?
Could it be problems in the inductor?
If I change the inductor L5 and Capacitor C64, will it solve?

@dc42

Today I checked the 3,3 Volts line on Board, it is ok, 3,29 Volts on my multimeter, I also Checked the 5 volts line and the results are 4,9 volts, then I disable the internal 5 volts regulator and add a external 5 Volts power, the results are 4,9 volts whit panel due plugged and the same without the panel due connected.
I tested the reference voltage on inductor L5 and Capacitor C64, the voltage is 3,29 Volts .
I checked the temperarture in Wifi Board and SD Card whith my PIR thermomether 33,3 °C and 33,2° C.
I put the voltagem for my power supply on 21,3 Volts; the result on Uet WEb Control is around 23,8 to 24,2 Volts. M122 Command report:

@dc42. Thanks. I will check

I am using a DUET 2 WIFI 1.03 with sucsses for more than 2 years. Today when I start a new job, I received a nmessage thath the board can not start because the , Vin is 34 volts, but the real voltage is 24 volts. The power supply is OK.

The issue:
When I try to move the motors it says "Attempt to move motors when VIN is not in range"

DWC shows 34.2 V in VIN
I have tested all fuses they show zero ohm
I have measured power in and it shows 24 V
I have measured from power to heatbed and it shows 24V
I have measured from power to hotend and it shows 24V
Wifi Blue light check
3.3V green light check
5V red light check
VIN blue light check
Z,Y, X stop red lights check
I have checked that VIN is tight (it is tight..)
All jumpers are in "stock" positions

People, I solved the problem. I add a new line iin my config.g a PanelDue port: M575 P1 S1 B57600. Nos its Works fine.

I changed my RRF 3.0 to 3.1.1, than the Panel Due dont show informations and show "conneting". I changed the firmware for the last 1.24 paneldue firmware and nothing was changed. I cannot use the panel due......

@JoergS5 Thanks. It is similar to my BL Touch setup um RRF 3.0. Thanks, I would try

@Phaedrux When I start to use Duet2wifi I used te BFP touch with RC servo with an older firmware, my dout is if its possible to use this configs um te mês firmware? config.g:
