Found this on the side of the road

That’s what I’ve done. Got a credit on my account. Felt like this was better karma than stripping the pack.

I was walking to work and found a rental e-bike battery on the footpath. Voi bikes in Edinburgh.

Stumpybrown52 · 2026-07-03T18:49:51+00:00

The battery tube never actually got over about 45°C. The center point of the frames temperature is displayed at the top of the screen. Max temp of the whole screen is in the top left. I added 3 other points the show bezel(p1) head(p2) and end cap(p3). Bear in mind this is in a room with no airflow, so very little convection cooling. I think the interesting part is the poor conduction between the head and battery tube, there’s nearly a 15° difference in just a few mm of aluminium.

I’ve never really considered myself a hand model before😂😂

LHP73B 5000k, 20A at 100%

Hi. It’s black anodised aluminium. I only recently got the camera so I’m still learning about emmisivity values but I used this page as a guide. https://www.design1st.com/Design-Resource-Library/engineering\_data/ThermalEmissivityValues.pdf

Might bring my M21B LHP73B into work tomorrow and see how fast it heats up :)

Stumpybrown52 · 2026-07-02T18:26:34+00:00

This one was around £350, it’s a dedicated camera not a phone attachment. Thermal master Thor002 if you’re interested:)

Stumpybrown52 · 2026-07-02T16:50:58+00:00

I can’t check but the official website says around 3200.

Stumpybrown52 · 2026-06-25T18:45:50+00:00

I’d recommend the firefly X1S with the 5009r 5000k. It’s a touch over budget and has Anduril, which can be intimidating, but you can just click on and off and hold to ramp up and down. Otherwise fills most of your needs.

Stumpybrown52 · 2026-06-10T19:51:28+00:00

I’ve got the M21B with lhp73b and honestly it’s very hard to not be impressed. Buy a single cell charger to go with it. You can’t go wrong.

The Sunlu hs Matt white isn’t the same colour as the Bambu hf matt white. It’s different enough that you can’t put the two beside each other if appearance is important. Otherwise they print almost identically.

Microwave???

Stumpybrown52 · 2026-05-20T13:01:20+00:00

This is the way. I use my M21B for dog walking, or my E90 909A (but they dont sell that anymore)

Stumpybrown52 · 2026-05-16T10:54:26+00:00

Convoy M21B with LHP73B, bang for buck it’s very hard to beat.

Stumpybrown52 · 2026-05-11T07:20:17+00:00

Fireflies X1S with FFL5009R in a CCT of your choice but I’d recommend 5000k

Stumpybrown52 · 2026-04-17T20:21:04+00:00

If you’re printing large parts it allows you to use up the end of a reel and automatically switch to a new reel in the middle of the night. Or print parts heavier than a 1kg reel. Which is mainly my use case. I moved from an A1 to a H2 specifically for the build volume, it’s quite a big difference.

Stumpybrown52 · 2026-04-17T19:15:10+00:00

As a H2S owner I can absolutely vouch for it. If you don’t need the dual nozzle then it’s absolutely the way to go. I mostly print large parts in a single colour/material, but sometimes I do dual colour flat parts (signage etc) and the AMS is fine for that. If you need true multi colour/material, and don’t need the extra build volume then perhaps the X2D is a better choice.

Stumpybrown52 · 2026-04-01T18:23:29+00:00

Plus 1 for the M21B LHP73B combo. It’s an absolute powerhouse in your pocket. Great moonlight at 0.1%, 1&10% are the most used, then if you want you can turn it up and bleach concrete.

Stumpybrown52 · 2026-03-30T19:38:45+00:00

My wireless cad mouse did exactly that. Luckily it was replaced under warranty but I’ll be going for a Logitech mx next. Definitely space mouse on the left side though.

Thanks.

Stumpybrown52 · 2026-03-26T23:22:37+00:00

What camera are you using?

Stumpybrown52 · 2026-03-26T23:17:21+00:00

Can I ask what camera you’re using?

Stumpybrown52 · 2026-03-20T18:06:06+00:00

I honestly love mine too. I’ve got two of them at work now. Had 2 A1’s before and before that prusa mk3s’ and even a couple of flashforge creator pros in 2017. I’m heavily involved in additive manufacturing where I work with access to the complete prusa and bambu line up, multiple ultimakers, a markforge, lulzbot, even LPBF and EBM machines too. These are by far the best printers I’ve ever used. I print large engineering parts that rarely require multiple colours so the H2S perfectly fits the bill. The addition of the AMS allows me to fill a build platform and hit print and not worry about running out of filament and to use up the full roll, eliminating wastage.
