E3D Titan extruder (Page 4 of 16)

I slice through the software, Repetier host, Slic3r, Cura or Simplify3D, at present I am using the speed settings already set in a fresh install of Repetier 0.92, I do think it's too fast and will be playing with the settings over the next few days.

The Prints are similar to when I had just the E3D v6, however I think the point of this further upgrade, after talking to Joshua @ E3D is that the Titan Extruder is able to print all filaments. With just the standard E3D v6 installed, on a non Bowden setup. It was difficult to successfully print flexibles. These filaments will also be tested over the next week.

I will be testing these settings tomorrow after noting the default settings. I can then judge any improvements.
Test Layer and perimeters settings:
Perimeters (minimum): 3
Solid layers : Top : 4 Bottom : 4

Test Speed:
Perimeters: 50 mm/s
Small perimeters: 30 mm/s
External perimeters: 50 %
Infill: 70 mm/s
Solid infill: 50 mm/s
Top silid infill: 40 mm/s
Support material: 50 mm/s
Support material interface: 100%
Bridges: 50 mm/s
Gap fill: 20 mm/s

Travel : 150 mm/s

First layer speed : 30 %

Test Filament Settings:
Diameters: 1.75 mm
Extrusion multiplier: 1
ABS
Temperature (°C) : Extruder: 230° - Bed: 90°
Cooling: Enable Auto cooling - Slow down if layer print time is below : 20 s - Fan speed: min=100 Max=100 (Other parameters = defaut)
PLA
Temperature (°C) : Extruder: 210° - Bed: 60°
Cooling: Enable Auto cooling - Slow down if layer print time is below : 20 s (Other parameters = defaut)

Hope this helps

With the standard E3D mod, I can print print flexibles but no faster than about 10mm/s or I get problems. Hopefully, the Titan will allow faster speeds.
I currently use an extruder idler printed with pla with has bearings in the centre. It's an improvement over the stock idler but I reckon I'll still go ahead with a Titan upgrade at some point.

The weight of the carriage contributes to shifting at higher speeds.  Especially as my steppers motors heat up during a long print, they are more likely to skip with the force that comes with increased acceleration.  Lowering the mass would reduce that force...

I would tend to agree with that.
From what I can see, the Titan is about 90% plastic so it stands to reason it will be lighter than the stock metal extruder assembly/mount.
That should certainly help a little with higher speeds although the stock stepper drivers will still limit this somewhat. They're also the cause of the steppers being noisy, something to do with them not being tuned properly, apparently.

There was another thread recently about changing out the stepper drivers with standard ones used for a reprap printers.

Especially on some of the older 1.0 motherboards, it looks to be almost a direct wiring swap out and much more simple than a complete RAMPS setup.

I would imagine higher quality drivers and this hotend/extruder setup would elevate a $400 davinci into a different class.

I'd still take a 1.0/1.0a over a pro just because of repetier!

This is the thread I read re. Drivers

I agree with you both, doing a few mods takes things to whole different level. We'd better keep quite or you know who may take notice lol

Stuart, how do you find loading filament with the Titan ?
I sometimes have a wee bit of a struggle getting my filament to line up with the entrance to the E3D. Another reason to upgrade I suppose.

Flexible will print with a standard E3D mod (without a Titan) but you need to slow the print speed right down to 10mm/s or slower.
I'm hopefull Stuart will be able to tell us he can print much faster with the Titan once he's had the chance to try flexibles.

Actually, I forgot I'm using a printed extruder idler with bearings, that might be the difference.
You also need to reduce any gap directly above and below the extruder gears to as little as possible.
This is my setup, sorry it's a bit dark but you can just about make out the filament guides above and below the gears.

I designed it myself but I can upload it here later if you like.

Edit : Here you go if anyone wants it. You'll also need two 3x8x3mm bearings.
         Mine is PLA, it seems to be harder wearing than an ABS one.
         I also printed one in Bronzefill (which is rock hard) should the PLA one wear out.

have the filament straight and it goes in so easily

Yeah, I'm finding that's the key with my current setup too.
