FixHub Smart Soldering Iron: Suddenly stopped turning on

Mon, 04 May 2026 07:23:25 -0700

I have been using the soldering iron today, set it down for 1h, came back... and now it won't light up when plugged in. The web interface does not find it. I don't get an USB device plugged in sound (should it even do that?).

Any ideas on how to narrow down the error?

It is about 2 years old. I used it maybe 20 times since then.
I tried multiple power supplies but nothing seems to help.

Does anyone have any more trouble shooting tipps?

Ryobi PSBCS02CN: Why do the lights on the tool keep flashing 4 times?

Sat, 02 May 2026 01:32:46 -0700

The tool hasn't been used in a few months since it did that while using it, but since then, when we try to use it, it just flashes. it's possible the motor could have over heated but I'm not too sure.

FixHub Smart Soldering Iron: Options for heatset inserts

Thu, 23 Apr 2026 15:34:34 -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!

Mon, 20 Apr 2026 08:18:09 -0700

I tried to update the firmware on my FixHub Soldering Iron. But the update failed partway through and now the iron seems bricked. It isn't recognized by either the Power Station or a computer.

Is there anyway to fix this?

Other Brand Angle Grinder: Lead shift ,Rewinding 24 bar 12 slot armature

Thu, 16 Apr 2026 05:30:06 -0700

I am rewinding an armature for an old-model metal-bodied Chinese mini angle grinder (approx. 700W-850W, 11,000-12,000 RPM).

Technical Specs:

- Core: 12 slots, 24 commutator bars.

- Dimensions: Core length 55mm, diameter 3.2cm.

- Wire: 32 AWG (0.20mm).

- Winding: Factory was 22 turns/coil (88 wires/slot total), but I plan to use 23 turns/coil (92 wires/slot) to improve torque and heat management.

- Pitch: 1 to 6.

- Progression: Retrogressive (1 -> 24 -> 23).

- Brushes: Positioned 90 degrees from the stator coils.

- Potting: Using two-part submersible pump epoxy (thinned with heat) in a vertical gravity-pour method.

The specific question is about the Lead Shift:

Because I am adding an extra turn (23 instead of 22) and the brushes are at 90 degrees, which lead shift is best to handle the high RPM and field twist?

1. Zero Shift (Bar 1 directly in center of Slot 1).

2. 7.5 Degree Shift (Mica directly in center of Slot 1).

3. 15 Degree Shift (Bar 24, one bar left, in center of Slot 1).

I am leaning toward the 7.5° (Mica Center) shift as a balance, but I'm worried about "fire-ringing" at 11,000 RPM. Has anyone done this specific 23-turn mod on these 12/24 armatures?

By ibot guess, the magnetic shift will ne around 18degree. I can't retrieve any original data of lead shift but from one saved coil, i get continuity from bar24 and 23, assuming first bar in center of slot is bar 1 and winding is retrogressive, connections moving left.

Dremel Rotary Tool: How to Test Dremel Sliding Switch

Tue, 14 Apr 2026 14:02:08 -0700

Hi all, my Dremel 3000 has stopped working and I assumed that because I was using it to cut small bolts and it was taking a while it had simply overheated or blown a fuse. Fuse in the plug (UK) is fine and nothing looks burnt out inside.

Based on other people's problems I suspect it's the switch that's failed but I'm not sure I'm testing it properly. I've got continuity in some bits but not others but I don't know if that's because it's faulty or because I'm doing it wrong. Can anyone talk me through how to test the switch correctly and what reading I should expect? Should I be getting 0 resistance or is a certain level ok? Just want to make absolutely sure it is the switch before I buy a new one.

Thanks in advance.
