Before the heat up blink was more of a slow pulse as it started turning orange. My firmware on both the power station and soldering iron is up to date and matching.

I could not find what the steady blue blink represents in any of the documentation. I'm still waiting for parts to become available to replace the screen.

I just updated the firmware and reset settings on the web console.

I'm using the provided USB-c cable.

What am I doing wrong? Why doesn't the manual have the error codes for the LED indicator light in a troubleshooting section?

the blue action/power button stopped working (doesn’t click, pressing it does not power on).

I’ve followed the instructions for disassembly up to removal of the front cover to diagnose the issue and the button on the UI board itself seems to be the most likely culprit (“mushy”, doesn’t click). Tried gently moving it and pulling on it with tweezers a bit thinking it might dislodge it somehow but to no avail.

The fixhub is basically new, I’ve got it as a gift as part of the soldering toolkit and used it twice, so paying for a replacement UI board for repair seems unjustified.

I’ve reported the issue to customer service but I wonder whether there is anything else I could try (perhaps some magic fix I’m missing being new to this) in the meantime, while waiting for a response. Thanks in advance.

An unfinished version update may leave the device unusable. Please retry firmware upload.

Have tested with the hard shutdown + DFU mode but still the same. Always "Unfinished Update"

I recently updated the Soldering station and Smart soldering iron to 1.4.3, and went about with soldering no issue.

After a little while, i got an error on the screen of the station, asking me to update to the latest firmware.

When i plugged it into a Computer and opened the ifixit console online, it tells me that the update is not complete. When attempting to finish the update, it will install no problem, but then continue to tell me the update still isn't fully installed, and wont let me continue to solder.

Downgrading to a later update, such as 1.3.x, will remove the onscreen error, but wont connect to the soldering iron. Even when downgrading the tip, the error still persists.

Going as far as downgrading both devices to Version 1.x.x, it will still say that the update is incomplete.

After disassembling the device for a visual inspection, there are two LED's flashing on the inside. D4 seems to flash almost constantly, but with D6 flashing when trying to perform any sort of update alongside D4.

Currently stuck as i have soldering jobs to finish but a soldering station that doesn't work.

Any advice or a fix would be great.

Thanks in advance.

Replacement battery packs were sold out here so i bought a DIY spot welder and six Molicel batteries. I replaced the cells and tabbed it the same way i saw it when i disassembled. I can read 4V from pos-to-neg on each cell. they all have the same chemistry (i drain/charge checked them).

I get 2.0V across the terminals/connector but I can't get the power station to come up.

I was able to hard reset the station and upload the latest firmware (1.4.3 at this time, i believe).

Is the BMS on the battery dead? is the pack not serviceable?

I would've just bought a replacement pack and called it a day but I'd like to try and salvage something from my attempt here.

Any info would be appreciated. Thanks.

Am thinking this would be via a terminal session, as the "knob" doesn't seem to show this option.

Also, is there any documentation on the CLI serial commands?

Some, like mcu-sn or toolinfo, are fairly straightforward, but am wondering if there's a comprehensive list of the other commands, similar to a man page.

after having not used the FixHub for about 5 months (put it into my drawer with about 70% charge), i wanted to solder something - and to my surprise the unit was completely dead (in my living room, so not cold/unheated).

I could revive it by charging it with a USB-A to USB-C cable - but that was a shock :(

So, i guess, my question is:

Is this expected? Is there some kind of "vampire drain" that empties the battery slowly but steadily?

No offense, but the whole product is a bit of a letdown - one of my tips i ordered regularly disconnects when i exert the slightest pressure, the other doesn't - everything is acting slightly more erratic than i would like it to (especially a) at this price point, b) this being an iFixit product) and if i now have to take special care of the FixHub once in a while... don't know, i just don't need another Tamagotchi i need to tend to at this point in life vs. something i can just put in a drawer, forget about it and be able to use it whenever i pull it out. Sorry for the rant.

This is not exactly a question, but I haven't found better place :(

While this suggestions are meant mostly for iFixit team, but because I couldn't find any e-mail to write to iFixit, I'm writing them here on the forum. And on the second thought, maybe you (the other users) have similar feelings like me and you can - so to speak - "vote" on those suggestions :)

Before I begin, a little story.

If you're from iFixit team, please read. If you here just for suggestions, just jump straight to "Suggestions" section :)

I'm not any pro user, not pro repairer. I just needed good soldering iron for very occasional fixes. Or maybe for future when I finally some day start learning with electronics... anyway, here in Poland most of soldering irons are available as iron connected directly to mains in the wall. Sometimes maybe with additional temp control and nothing more. And it takes few minutes to heat up...

So I asked friend who did some electronics and he immiedately proposed me iFixit. Well... it wasn't really proposal... it was more like "I've got iFixit, and you must get it, there's nothing else so good". (Friend moved to US, I'm still in Poland)

I looked into website, ordered with kinda pain in the wallet and tear in my eye due to price. Yeah, I didn't want to order small pieces, so I decided to order probably most expensive set "FixHub | Power Series Soldering Toolkit" with almost everything. Along some tools like Magnetic Pickup Tool and FixMat (that's a cool one!).

I've had slight problems at first startup (read 1st suggestion in which I explained), but after 2 uses... I must say... I was amazed and this is exactly textbook example of difference between "price" vs. "value". Because this thing is %#*@ cheap by what it gives!

• Battery pack so I can use it on-the-go? Hell yeah! I do occasional side gigs (literal gigs lol) being technicial/live sound mixing guy, and I've seen multiple times that other techs fixed something right before concert because something broke. Other tools I looked in the shops? Need standard wall power... and while there's a lot of power at concerts, it's always very inconvinient to iron with cable hanging on the back of the rack in half-darkness or whatever, so it's great to have battery!
• Heating speed - ON MY GOD IT'S SO FAST!!! It takes me 10x longer to take this Hub from my closet, open pouch, take the Hub off, take the USB-C table off it, take the iron out of it, connect together and start than actually wait for heating... The tip of iron gets into 270C in just few seconds! There's your value, RIGHT THERE! I love it. No need to connect ironing tool into socket, and go make a tea and eat half a dinner because now you have to wait 5 minut with traiditional ironing tool to heat... not to mention, how unprecise such heating it, while in iFixit I can specify temperature very precisely.
• Oh, should I mention the solder cap so I don't burn myself by accident when I finish using it?

I also ordered this to be able to push insets into my 3D prints (so I need to heat inset and just push), and I was worried that minimum possible temperature of 200C is too high for this, as PLA starts melting at about 65-70C. Turned out... I didn't need to worry, because I would need constant heat of 65C for weeks/months in order to PLA start melting. I started with 200C and I wasn't able to melt that plastic, so... yeah, no need to worry if you want to use this with 3D printing, as you still need to set it to 250-270C like your 3D Printer does in order to melt plastic fast :D

After those experiences - even including initial problems - it's still the best money I've ever spent. Even for my very occasional use (just few times a year at most!).

Finally the Suggestions:

1. Web interface

At first I've had problems starting device, read few articles, turns out some devices were sent with some weird problematic firmware and I just had to do update. Sounds easy right? Especially that I found out, that I can simply connect device into computer, and there's nice web site that can access RS232 devices - and this soldering hub to be specific.

Well... there was issue I didn't understand at I don't think I read somewhere specifically - The Hub has separate web UI than soldering iron itself.

I mean - it's obvious that they have since they are different devices, but it wasn't exactly clear.

What I mean is: on Hub web UI I can upgrade Hub's firmware. But I need to connect iron separately to computer in order to upgrade Soldering Iron firmware. Then I also discovered that I can control Soldering Iron from Chrome (not exactly useful feature to me, due to where my docking station is placed on the desk, but hey, cool feature and might be very useful in some occasions!).

The problem I had is that on Hub's web UI, I was seeing that Iron was connected to one of the USB-C ports, so I was somehow trying to find a way to set parameters of Soldering Iron and upgrade firmware (essentially, access UI of the Iron itself since this is was I was seeing in Google Search)! But it turned out to be not possible and I just had to connect Iron separately.

So the suggestion is:

• Can we have possibility of upgrading Iron's firmware along with controlling specific Irons through Hub's web interface? That would make updating firmware and general operation far easier to understand for first-time users :)
• Also, on https://www.ifixit.com/fixhub/console please explain why Firefox is not compatible. Given how false such info are on many websites, I tend to simply switch User Agent to access website on Firefox. But it turned out, you need Serial access through browser which is really technical limitation this time. Please just include "Hey, you're browser doesn't support Serial access so you need to use another one" :)

2. Offline web UI

Given what I wrote about live concert situation, usually there's no internet at the place, and even if we could use LTE/5G, it's very inconvinient as we already have our devices usually connected to mixers or other audio control equipment, so switching networks (thus disconnecting Wi-Fi) is not really convinient as there's quite high level of multi-tasking during stage setup.

That might be already done as it's possible to configure web page to save itself into browser in a way to work offline, I haven't tested to be honest.

3. Official Longer USB-C cable

The Hub supports up to 2 soldering irons at the same time. Personally I don't find need for this, but it might be very useful for some people. The problem I discovered is that the USB-C cable that somes with Hub+Iron bundle is ok for personal use, but I feel it might be slightly too short for dual-people use. I might be wrong because I was not in two-people situation - so let the others decide if this suggestion is even valid in the first place.

It's not really problem to buy longer high-wattage USB-C cable. But the official one is very flexible which is great for the ironing task, and finding something so flexible is kinda impossible.

Thanks iFixit!

The error message stated: "Make sure you do not already have another connection open and try again."

I tried the following troubleshooting steps without success:

• Fresh boot with no other applications or browser tabs open.
• Tried multiple USB ports.

The solution that worked for me was adding my user account to the dialout group. I used the command: sudo usermod -a -G dialout <username> (replacing <username> with my actual username). After running this command and then logging out and back in, I verified I was added to the group using groups <username> and was then able to connect to the web console successfully after a reboot.

This seems to be a common permission issue on Linux systems for accessing serial ports.

I've recently started using heat-set inserts in some of my 3D print designs, but I've run into a small issue — the only soldering iron I own is the iFixit one, and unfortunately, it doesn’t currently offer a tip designed for heat-set inserts.

Has anyone had any success using any of the four standard tips for this purpose? Or is a dedicated soldering iron with a compatible insert tip the only real option?

Would love to hear your experiences or any creative workarounds you've found!

Not finding any usable help anywhere as third party apps to "Install" a serial port don't really seem to do that. Has anyone with a mac been able to update the soldering Iron firmware and if so I'd appreciate some help...

The web console is great but not always an option if you are in an offline environment. I see that there is a basic help command but it does not seem to give much detail on individual command usage.
