Problem Printing

[Marbelup]

That was quick! It arrived today. I printed some track samples and it's definitely stronger than pure PLA.

Andy - Have you posted photos of your 3D printed turnouts and track?  I would be interested to see what you have done. 

 

I have printed some lengths of sleeper bas to suit flat-bottomed rail for Sn3.5 (16.5 mm), S standard gauge (22.5 mm) and dual gauge.  I haven't attempted turnouts yet, although I have made many turnouts previously on timber sleepers using Pliobond glue to attached the rails.

Hi Richard,

 

Some stuff here http://www.rmweb.co.uk/community/index.php?/topic/100879-printing-turnouts-on-a-3-d-printer/page-8?hl=andyid

 

and more recently here http://www.rmweb.co.uk/community/index.php?/topic/124414-00-bullhead-printed-pointturnout-bases/

 

There's also quite a lot on the Templot Club http://85a.co.uk/forum/index.php?show=recent

Thanks Jim.

 

I've had a look, and it isn't a loose connection, it is a broken one !.  One of the power leads has broken off where it is (was) soldered onto the plate.  I'm guessing that it is a metal fatigue issue as the wires bend when the plate slides backwards and forwards.  In theory that is easy to fix, but it is "big soldering iron" job, and I don't have one.  But I think I might know someone who does.

 

Regarding the blue tape, sometimes that works for me, other times it doesn't, and there doesn't seem to be a pattern to it.

It took a while, but a friend armed with a big soldering iron visited today, and I now have a working printer again

 

I've also switched to using a brim, and the print went like a dream.

 

Thanks again for the advice in this thread.
