I've posted about bigger filament on the rigid.ink Facebook page so who knows maybe someone has seen ultra thick filament or may have other thoughts.

How about granules instead of filament? ColorFab sell them. Best of luck in devising a system to use them though!! ? I bought some several years ago with the idea of getting my brain into gear but it hasn't happened yet. ?

Now I see why you're interested in using very big nozzles, Chris ? Ah... Aluminium tubes for the main supports - even my Giant printer couldn't accommodate those. I'm limited to 700mm in height ATM. But I have BIG ideas and who knows what the future may bring. Once I get a spare room cleared out it's anyone's guess what I may put in it ?

Hot melt glue can be useful too but still best to mount connectors on the box.

I always do the same as you Hugh. Connectors on PCBs or even worse on stripboard (Veroboard) are often a source of trouble and I've had plenty!!

I used a breathable membrane between framework and cladding but I don't really know what it does. Just took advice on here.

They are designed to be used with PCBs rather than Veroboard and mounting many types of PCB connector on Veroboard can be a problem. You may have to drill holes where there aren't holes already - this can be difficult if close to a hole that's already there..

As a result of the above the X carriage is much simpler and interchangeable hotends become relatively easy. The other change is to use a bigger fan for parts cooling as the previous one proved insufficient. As a result the air duct and "blower" parts have also been redesigned. Interchangeable hotends mean that the heatbreak does not need disturbing when changing nozzle size - nozzle, heater block, heatbreak and cooler will be changed as one unit. It also means that the alternative size of filament can be accommodated.

Had a complete rethink about cooling the heatsink on the hotend and decided to ditch the water cooling and go back to standard air cooling. The thinking behind this is that the amount of heat to shed from the cooler side of the heatbreak only depends on the nozzle temperature, the thermal conductivity of the heatbreak and the temperature needed on the cool side to prevent the filament softening where it shouldn't. The available power input is higher in the Giant printer due entirely to wanting to melt more filament in a given time. The control system supplies only enough power to the heaters to maintain the required temperature for extrusion. Granted that the printer is enclosed and warmer than ambient when printing ABS or ASA but these filaments have a higher softening temperature anyway. I shall be using the same cooling system as in my Titan printer which is also enclosed and warmed inside and that cooling works perfectly well.

Ah yes - I did wonder.

Do you mean Hornby Dublo?

IF!!!

It's got a cute little face! ?

So am I - very trying!! ?

That's the same track gauge as "1-Gauge" guess the scale is a bit different.

Welcome home James ?

Great stuff - made me laugh!!

A packet of elastoplasts ?

A bit off-topic (though we did use some fence posts) - some years ago when Tim was alive we built a full size narrow gauge railway from the big shed (used as a cattle barn by previous owners) round to the back porch and used to carry wood and anthracite for the Rayburn in the kitchen. It was 2ft gauge industrial track previously used in a coal mine in North Devon. Tim was "into" narrow gauge railways in a big way! Taken up some time ago though just leaving track from the gates into the barn and on to the goad shed for bails of silage and straw for the goats, of which one remains.

I think it's one to prevent splitting but can't remember now.

Lovely ??

WOW! That's real purdy!! ?

Mine is always low!!

New version.

Depends how big the discount was. But it will severely affect any resale value.
