FixHub Smart Soldering Iron: FixHub Web Console Connection Error on Ubuntu(Solved: user permission)

Wed, 14 Jan 2026 11:44:54 -0700

I was encountering a "Connection error" when trying to connect my FixHub Smart Soldering Iron to the web console at ifixit.com/fixhub/console. I am running Ubuntu 24.04.2 LTS and using the latest Google Chrome browser.

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 (replacing 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 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.

FixHub Smart Soldering Iron: Smart Soldering Iron doesn't heat up, blinks blue 3x when on.

Sat, 28 Mar 2026 09:56:52 -0700

I'm using the iFixit Smart Soldering Iron with an iFixit 65 watt fast charger. Plugging them on together causes the indicator LED to just keep flashing blue 3 times fast.

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?

FixHub Smart Soldering Iron: Can I use a generic 20-40W USB-C charger to run this soldering iron?

Tue, 02 Dec 2025 09:04:24 -0700

I bought the FixHub Smart Soldering Iron from them at a booth at a Makers Fair. The guy didn't mention that I had to use their overpriced power supply but did try to sell me one. When I just wanted the iron he didn't dissuade me... But I can't find the answer to this question on their site - they only address their own power supplies in all the literature (etc.). Anyone know ?

FixHub Smart Soldering Iron: Is there documentation for the serial console

Sun, 16 Nov 2025 19:54:33 -0700

Is there any documentation for using the serial console when directly connecting the smart soldering iron to a PC?

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.

I just unboxed my NEW Fixhub. Everything seems to work fine except for....

Is there some form of release for the tip? I saw a guy on line just pull it straight out. Mine doesn't do that. It doesn't rotate around or move in any way.

FixHub Smart Soldering Iron: Options for heatset inserts

Sat, 03 Jan 2026 16:12:54 -0700

Hi everyone,

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!

FixHub Smart Soldering Iron: Does this have a "power bank keep alive" feature?

Tue, 03 Dec 2024 16:11:59 -0700

Does the iron itself have a feature that can keep a power bank alive? Some power banks will shut down if the device does not draw enough power.

Other popular USB soldering irons can do a "power pulse", draw a bit of extra power once every few seconds, which will keep a power bank "alive".
