Setting up Cartesian Printer.

It is supported on the Duet and S3D does support FW Retraction of a kind they use M101/102 and 103 codes which according to the RepRap wiki on GCodes has been deprecated in all but TeaCup firmware so we can't understand why S3D went that way at all
Fortunately you can post process all S3D Stuff very quickly within the SW Package by using the Scripting section to replace those M103 with G11 or whatever is required but it would be better if S3D Supported it on a FW Requirement basis it can't be that hard to do. mind I am not a software engineer so what do I know

Ah, great thanks Doug!

That's good to hear. I'm thinking of switching from slic3r to S3D myself - just need to know if it can do 3 (or more) colour prints. It looks like it has some good features but might be a bit complicated for an old guy like me:)
I'm an old bugger myself, and if I can use it I'm sure you can.

I think I beat you all hands down. 60. Old enough to be the winner here?
New version of S3D came out and they now specifically support multi extruder setups (3 and more)

Unfortunately not Deckingman has that honour (I'll him admit to how much lol)
AS for multi extruders they have supported them for ages just not the easiest thing to get your head arround the main issue here is the Firmware Retraction that is essential for mixing hotends such as the Diamond?

I was born in year of our present queen's coronation.
Ian.
P.S. If you bothered to check when that was, you should be ashamed of yourself for not having anything better to do.

I know when it was Ian but Lykle is a dutchman in Cyprus LOL. and for his benefit it was 1953.

Perhaps we should start a club for Over 60's 3D printing enthusiasts? I'd be eligible too!

Well you would have to wait a few months till I'm Eligible David (Mar 2017 for me).

OMG - old farts club!

Good idea. Will that mean concessions get a discount on Duet products?

Steady on….I'm 47...which my sons assure me qualifies my entry into any old farts clubs.

Nah, your just a young slip of a lad.

Still think we should push for an Age Concession Ian? (Very tongue in cheek LOL)

So I'm trying to dial in my extrusion properly.
I've done the 100mm extrusion and am getting a constant and repeatable 120steps/mm for my extruder motor. Quite confident that is set correctly.
My understanding is that once that is done, I need to measure the diameter and work out my extrusion multiplier for each different type of filament I use, and enter the value into my slicer (S3D in this case).
I've entered the filament diameter (1.714mm, averaged over 5 points) and printed a single walled hollow test cube in 0.1mm layer height to measure the real wall thickness, which was set on manual 0.48mm.
Came out very nice, but is 0.55mm thick.
Is that excessive? How do I calculate my extrusion multiplier setting? It's set a 1.0 at the moment.
If I divide the difference (0.07mm) into 0.48, I get 6.86.
So do I just set my multiplier at 0.9314 and try it again?
Does this setting work over all layer heights?
-
I don't bother measuring the filament. I just put 1.75mm and extrusion multiplier 1.0 into the slicer, do a test print, and adjust the extrusion factor in the slider on the web interface to get good top solid infill. Then I make a note of the extrusion percentage shown in the slider, and use that value in future for that roll of filament. Ignore the single-wall thickness, it isn't a good test.

So I tried this and got these results.
I did still have my own filament diameter entered, forgot to reset it to 1.75mm, but used the extrusion bar on the DWC to make adjustments on the fly.
Percentages are written on them, which do you all like?
-
Personally, not terribly keen on any of them. Just for the hell of it, try dropping the extrusion in 5% increments until you get obvious under extrusion and see how the finish looks. This is the subject of another thread I've started but for some as yet unexplained reason, I'm getting best results using 70% extrusion with everything calibrated and triple checked. (Yeh, weird I know).
