@incurio I replaced 7.5 and 1.5 fuse and it is working, thx

@droftarts

Here is 7.5A fuse and 1.5A side by side.

I think 7.5A is blown. Not sure about 1.5A it looks clean.

I checked the 15A fuse also and it looks clean it has a connecting metal strip

Please Advise,

Thx

@droftarts I measured the resistance of the heating element and it showed very little resistance 0.3 , I think this is the culprit. It is the only used component that I used.

Assumming this is correct, what is the fix for this? Do you have a part I should look for to attempt a fix?

thx

@droftarts here is photo when powered up using the micro USB

There is a red led light on near left side of image, I hadn't noticed that before.

Will fixing this require soldering work to replace fuse?

Thx

I am running duet 2 wifi board on e3d toolchanger.

I have all 4 tools on my device and needed to rebuild tool 2 due to a print failure that clogged up the hotend.

When I picked up tool 2 and proceeded to turn on the hotend heater it became unresponsive. I was re-using a heater component I had recovered from another tool for my rebuilt hotend, which was connected to a new thermistor same part cooling fans and hotend fans.

I shut down the printer and powered it again and it is only showing a blue LED light. The blue led light that was coming on was the one at the same level as the motor connections and not near the sdcar. I couldn't connect to the printer any more. Web interface was not up.

I then proceeded to plug in the usb cable to my laptop after verifying that the sdcard was not corrupted.

Wifi came back up and I was able to connect to my printer. The 2 led lights on duet 2 near sdcard slot lighted up and appeared to look ok. I even attempted to home the printer but that operation failed, which I expected since 5v doesnt have enough power for that.

I also measured the voltage at the dc power out to the duet 2 , when the blue light was on and it was 24v .

Any help would be appreciated to trouble shoot this further.

Thx

Ratrig v core 3 issues. I ordered a rat rig vcore 3 with duet mini 5+. 1 yr ago

I never got to build it until now. I am having issues with the board not sure it is defective. I am using reprap v 3.4.1 latest. I was successfully able to print with it only 2 times.

The red led light on duet mini is blinking 3 times every time I turn it on. Once I home, then turn on the hotend I am no longer able to connect to the web interface.

The 1st time I saw this error, I was getting errors about the web interface having SD card issues for ex. A folder wasn't available or all my print files disappeared. I then tried switching to using 3 different SD cards and still seeing the same issue.

At one time I thought the wifi wasn't working. It appears that my troubles start when I turn on the hotend. Shortly after that I am unable to connect to printer.

I am using bl touch and all the sensors and end stops and motion system appear to work ok.

When I lose connectivity then turn off printer, I am usually able to connect to printer. I am only using web interface to connect to printer.

The message I posted above is what I sent to ratrig tech support and they asked me to repost here, for authorization: I found an issue that seemed eerily familiar to what I am seeing at this link also:

Please advise.

@phaedrux Hi, the store I bought this product is asking me to get approval from some one in your team to get a refund for this product.

I am using the same fans on other fan slots with no issues. The same fan that is not powering up on P8 is working fine from both a secondary power supply.

Please Advise,

thx

@phaedrux I forgot to add in addition to testing using a separate 24v power source.

I also plugged in the fan for P8 which was not working into P4 slot, then picked up tool 2 to see if it worked, which it did.

thx

@phaedrux
There was a fan plugged into that slot and it does power up when I use a separate power supply providing 24v and 0.1A power. I removed that fan so the damage could be seen easily.

Is there a brand of fan that is not supposed to be used by these boards?

All my part cooling fans for my 4 tool changers are using the same model of fan.

Thx

@phaedrux All the fans are working when I use a separate 24v power source.

Not being an electrician when I noted there was 24v pwr on bad fan -- I eneded up replacing the wiring on my fan until I realised ( dumb me ) that it should have initially read a value of 0.

I didnt realise that the fan itself might short out.. i am using 24v fan winsinn -- I did read some article about them being unreiable fans.

What can I do to prevent a short from fan blowing my mosfet?

@incurio I am using the same kind of fans on all the toolheads.

@phaedrux I am not an electrician is this something I could fix? i.e replacing mosfet?

what kind of wiring issue might cause mosfet to blow?

thx

@incurio here is timeline:

been printing filaments that dont need part cooling:
-- noticed that fan on P6 not powering up.
-- verified connections on fan workng ok, then bought a new replacement Duex5
-- installed Duex5 fan P6 working , now P8 not working --
-- close examination of new Duex5 shows burning -- ask for refund or replacements ( asked to post in this channel )
-- put back old Duex5 now fans P6 and P8 not working. same issue Fan volt reads as 24V when not powered on.
-- dont know root cause yet -- is this a known issue that can happen to Duex5 ?

@phaedrux That was the replacement board that I got -- and it was fried .. not sure how/when that happened.

I pulled that out and reverted to original board and now another cooling fan not wrking in original. But original doesnt have any burn marks.

I dont think I know what is the issue -- for ex: is it normal for part fan to read 24v even when not running? what could be causing that?

I bought a replacement Duex5 board because my current boards part cooling fan was not working for P6 slot. ( order #79384 )

When I installed the new Duex5 , P2,P4 and P6 fan were working fine but not P8. After some measuring on why new board was having an issue on different fan slot -- I noticed that the there was some burnt material near the P8 slot see attached.

The current Duex5 I have v0.10 with part cooling fan issue doesnt have any burn marks any where.
