Re: Resin print artefact

I guess you could prove the printer artefact hypothesis by printing at a different angle, and seeing if the line disappears? It seems like a strange place to get pooling however.

Re: Ffestiniog Bug Boxes and Flying Benches - first run around the garden

It's certainly quicker using the laser cutter, but you do need suitable space to run it. They produce a lot of smoke and burnt particles, so good ventilation is a must. They need to be watched while cutting, in case they set fire to the work piece and finding the right materials at the right price i...

Re: Resin print artefact

If you analyse the chitubox output layer by layer, is the artefact visible?

Best guess would be an inverted surface. What happens if you import it into Microsoft 3D builder? Does it suggest a repair is required?

Re: Generating a driver from photos

I know this is an old post I am dragging up, but I have some experimental software that create a 3D model from just a single photograph. If you are still looking for a model, please let me know, as it might be a fun thing to try.

Thanks for the heads up on the video.

I had not used the Share link. Corrected now.

Ffestiniog Bug Boxes and Flying Benches - first run around the garden

This week's project has been getting this little rake of 3D printed and laser cut Ffestiniog coaches ready to run. They are based on the Thingiverse design, but with more laser cut elements, including sides and ends. Couplings are magnetic choppers, based upon the supplied couplers, but with a small...

Re: Point Operation

The servos are MG90s with metal gears. I found you get much less back lash than with the nylon geared ones, so they hold the blades in position much better.

Re: Point Operation

I power my servos using a small 12V supply. The servo board has a built in power converter to the 5V the servos need. Herewith a couple of photos, showing the installation, and the older now disconnected point rodding, along with a quick video. Apologies for the rough running, I didn't realise my wi...

Re: Point Operation

My points are operated by servos driven from a simple 4 channel servo controller. This sets the throw and speed of operation, and just requires a simple toggle input. I use a cheap and cheerful 4 channel radio control key fob, with each point toggling on a button press. Prior to this, I had manual p...
