Good to see Templot Club back on line (hope you have had a fruitful time) and that COT track is back.
Its also very good to see work going on with 4mm scale COT track, hopefully we will see progress this year
I see nothing wrong with COT track at the moment only being able to do basic requirements, eg: turnouts. Yes Templot is capable of doing so much more, but for the average modeler, that's all they need
In 7 mm scale I have the ability to design and print the most detailed turnouts on the market, no manufacturer of professional track builder comes anyway near with commercial products available. That's before we even think about them being bespoke !! The level of detail is second to none. That's before we look at how easy they are to build !! Nothing in 7mm comes close. Plus I have not mentioned the plain/flexi track
As I have said for me the biggest benefit is the detail, but with ever rising prices, my turnouts cost me a fraction of both the RTR and kits available. My Neptune4 has paid for its self in months
We may still be in the Chinese year of the Dragon, but for railway modelers 2025 is the year of the COT (track)
It's doable, just, on a Neptune 4 with a standard 0.4mm nozzle, but requires dozens of changed settings and a different slicer. I'm not too sure that I want to go ahead with it -- I'm dreading having to explain it all. For example FDM plug-in 4mm chairs could be used instead of resin chairs with laser-cut timbers. But not with loose jaws, for FDM they need the glue-on stub jaws if not solid-jaw.
