FAO: Rupert - 3D printer carriage

[Toby Williams]

I had another go with the part, however failed at the last hurdle - I think I was running too close to the machine limits and it looks like it lost a step. If the curve over the small hole isn't a critical dimension, then you'd be welcome to use the part. 

I held the metal by screwing down to plywood which was held in the vice, which worked great. (although the washers did mark the part slightly)

I have left it on top of the Boxford if you want to inspect it for "use-ability".

Model is here: http://a360.co/2tD7noR

Wohoo - Thanks very much.  I'll pop in tonight and pick it up.

A testament to the AutoCad Fusion 360 pathway :)

Maybe a little bit of fettling/blasting can hide the very slight ledge. I am sure you will see what I mean.

Brilliant – what does the part do?

Its a modified RepRap X carriage.

My current one, gets worryingly close to melting as it's just PET-G.  I figure if we manage to melt a Ally one, then something's gone seriously wrong.  This is starting to try printing the new high service temp plastics, which need some much hotter print temps.

Have you changed your nozzle to an all metal one? If you have one with the ptfe liner it can give off poisonous fumes at higher temps

Did it work?

[Mr E]

I'll find out this weekend :) It certainly looks a good fit.

Re the nozzle - yes we're switching to a different one :)

By the way, in case anybody was wondering: 

"if the Boxford can make this then surely that proves that it works fine and we don't need to upgrade it?" 

then I would point out that this was a complete pain to do, because of the Software. Of the several hours that it took to make the part, the spindle was stationary for +90% of the time. We'll never be in a place to throw a bit of metal in the machine and get this part out, it's far too complicated part and we don't have enough tool holders. However, it can be a lot easier then it was.
