Round 3 - setting up pronterface to use slic3r

[stochastic forest]

Hello all, 

I'd like to follow the instructions here http://tvrrug.org.uk/slic3r_setup to setup a slicer.

My Pronterface installation seems to have picked up skeinforge as it's default slicer, probably because that is

supported in my linux distribution.

Does anyone have the relevant slice command and sliceoptscommand to persuade pronterface to use slic3r ? 

many thanks,

Matt

Don't use the integrated slicer in Pronterface strange things happen to saved config settings, use Slic3r freestanding instead ...

IE
1 Create scad in OpenSCAD then compile (F6) and export as STL
2. Import STL to Slic3r and slice, export G-Code
3. Import G-Code to Pronterface and print

The latest versions of Pronterface have proper support for selecting
different Slic3r profiles. Prior to that I set:

Slice command:
slic3r --load /home/barnaby/.Slic3r/slic3r.ini --load
/home/barnaby/.Slic3r/filament/tvprusa.ini --load
/home/barnaby/.Slic3r/print/tvprusa.ini --load
/home/barnaby/.Slic3r/printer/tvprusa.ini --output $o $s

Slicer options command:
slic3r

And found the integration worked perfectly. Obviously alter 'barnaby'
to your home directory, and 'tvprusa' to whatever you called your
settings.

... but be aware that the Linux and Windows versions have diverged a bit
in the past to the extent that the Windows version was broken after a
July 2013 update that was OK on Linux.

I currently use "printrun-win-Mar2012-slic3r"

The issue is still open on GitHub ..

Thanks for this barnaby, it worked nicely, first print achieved.

Picture please?

Wow! The traditional "Hello World" for a TVRRUG printer is a mini-mug (and the convention is to drink something alcoholic from it - once printed.

 

That is more like "War and Peace" at the first attempt. Well done!

Interesting that you've not got the wooden bed.  Seems to me that this acts as a heatshield to the plastic parts below.  I wonder if you will get sag in them over time without it?

@Norro

I thought I'd try a different approach to the wooden bed ( mine was a little warped and delaminating  ).

As you suggest, it wasn't clear if I would need to add extra radiant heat shielding to protect components underneath. The only printed parts exposed to sustained

heat are the two cable clamps on the perspex carriage and the bed height adjusters.

The former don't immediately seem vulnerable to warping as they are in compression and minor distortions in the latter will probably be compensated for during bed levelling.

I've measured the temperature at the upper surface of the perspex carriage and it was stable at 31C with an ambient of 21C, this doesn't seem too severe, this is with  the bed running at 70C as I have it inverted to facilitate cable routing.  

So far things seem tractable, long term it remains to be seen if it all works out.

The benefits are around an extra 15mm available travel in the Z direction and a lighter Y carriage.
