Alternative uses of a 3D printer: Toner transfer on a watch dial ( i.imgur.com )

I've watched a lot of resources about toner transfer over the last few days, and while everything was quite experimental and empirical, the main gist was : heat + pressure = toner transfer. As I didn't want to, for obvious reasons, cook a dial full of unknown glues, paints and metals in the family's kitchen oven, I started...

Here you go ;) https://lemm.ee/post/35636122

I 100% agree with you, a professionally made dial is a work of art and should be absolutely perfect at any magnification. This is just a fun, cheap summer watch project for my own enjoyment ;)

The best looking alternative would have been to have the logo made by electroforming. They look perfect and very professional. Unfortunately the MOQs are usually quite large and therefore expensive, I couldn't justify spending half the price of this project just on a logo (even if I had enough spare logos for several lifetimes).

If you can clamp a whole PCB on the bed, that's a perfect application ;)

Thanks <3

Thanks for the feedback!

I'm pretty happy with the transparencies tbh. Although on mine, there seems to be two sides, one that gives a fuzzy dirty effect with a lot of stray toner around the actual print (looks like static), and the other side that gives perfectly crisp prints. Unfortunately I can't really tell the sides apart.

Apart from that small speck of dust that prevented the transfer at the top left of the logo, the sheet came out perfectly clean, the totality of the toner was transferred to the dial. For PCB transfers where you could probably keep the sheet intact (I had to cut mine to fit between the applied indices), that would also mean the sheet would be almost indefinitely reusable.

Than you so much for such a detailed analysis!

For reference, I've had a (heavily modded) Creality Ender 3 V2 for a few years, and I've hit a limit in terms of speed and quality.

The filament path between the extruder and hotend is poorly-constrained, making it a pain to load
The auto-z calibration is often just a smidge off
It uses a custom nozzle/heater

If it's possible to install a Stealthburner instead of the standard extruder/hotend combo, it might solve most of these issues. Maybe some people are working on a V6 or Mk8 style hotend (I have a metric fuckton of Mk8 nozzles laying around)...

The fans are absurdly loud. All of them.

OK Noctua upgrades then. Compared to an already absurdly loud Ender 3, is it worse?

The mainboard is effectively a BTT CB1 and Fystec Cheetah on a single board
Their software customizations are of dubious quality

Would a Voron-style mainboard + RPi + standard Klipper solve these issues or are there fundamental incompatibilities?

Thanks!

Ah perfect timing indeed.

The key takeaway indeed matches yours: it's not a Voron despite being heavily inspired by it, there are some annoyances but at this price point it's forgivable and most of them seem to have workarounds (someone in the comments suggested letting the machine fully soak heat before performing Z-offset calibration), the open-source nature might bring a lot of third-party upgrades in the future.

Also, the reviewer's unit has some abnormal wear on the belts. Does it match your experience?

All in all, it seems to be a decent budget CoreXY printer with a very large volume at 1/3 the price of an LDO Voron kit + PIF parts, with a much quicker assembly but some potential pitfalls.

If this eventually becomes the Ender 3 of CoreXY printers that can be frankensteined into a a much higher quality printer over time, I'm all for it.

Public transport in Europe is often in a sorry state, but trust me, it's nothing compared to the US. Here in France, a lot of regional trains are very unreliable at best but at least high speed trains on dedicated tracks are fine (very expensive, but ok).

I don't remember UK rail to be a shitshow and/or that expensive but my only experience is going to/from central London to/from neighboring counties and it was fine.

But in the US, oh boy. About 15 years ago I was living with some roommates in Campbell, CA and we went to SF one day. 1h drive mostly on shitty concrete motorways, including probably around $5 of gas. They were heading north for a romantic getaway so I went back to Campbell by myself. It took almost 4 fuckin hours, on maybe 4 or 5 different private companies, and cost me like $25 to get back.

Public transit in the US is so fucked up im almost convinced it's by design.

My ADHD brain panics if I need to catch a scheduled train and if I'm not actually there at least 1/4h in advance I melt into a puddle of anxiety.

But city trams and metros are absolutely fine. If I don't catch this one, there's gonna be another one in a few minutes. No worries.

Busses that are scheduled every half hour at most drive me mad tho. Did I miss it because it was 10 mins early because fuck schedules or is it gonna be 15 mins late?

Go AMD. The open-source drivers already provide the best performance compared to the closed-source ones, and are included in the kernel and Mesa, which means the cards will work out of the box. For the best performance and latest drivers and optimizations you should switch to a distro with more up to date packages than Debian if you plan on buying a current gen card tho. For example, Fedora is a very good mix between working OOTB, ease of use and bleeding-edge packages.

nVidia is... difficult. The open-source drivers are getting better but are still way behind closed-source drivers, and each closed-source drivers version only works with a single kernel version. It might work OK as long as the drivers and kernel are kept in sync (I think Pop! or Nobara have nVidia specific versions for this reason), but otherwise each kernel upgrade is a risk. Plus nVidia drivers are basically shit with Wayland and cause a ton of issues.

Intel has a good track record with iGPUs so discrete cards should be as trivial to use as AMD ones, if more at the entry-level performance-wise.

How do you store your grounded coffee? ( slrpnk.net )

Hiya, just quickly wondering how people store their coffee? Mine is in a tin box I got second hand, cos I thought it looked nice. Any rules regarding storing grounded coffee? I don't store much at the time, it's just if I grind a little too much and what not. I'm assuming the general thumb rule for this is to store it in a...

Same. Old DB2 base from the 80's that was migrated to Oracle in the 90's then to Postgres in the 2010's.

And the people there know all the column names by heart 😅

Ubuntu's version of Gnome is heavily modified to look and feel like their old Unity DE though. Vanilla Gnome like in Fedora or Arch is a vastly different experience.

There's also a community built Flatpak if you're ok with that
