Skeinforge settings

Hi Grogyan

From SF40 onwards it requires a change to your firmware. You need to recalculate the E-STEPS-PER-MM value to represent the steps required to push 1mm of filament into the extruder (as opposed to steps required to push 1mm out of the extruder). For details of how to do this see this post:

[forums.reprap.org]

You will also need to set flow rate and feed rate to the same value with SF40+.

I have attached some of my skeinforge settings. The most recent dates are my current settings I use. Also included is my archival and retrieval tool for Skeinforge. Look at my blog for details of how to use it.

Regards,

James

I have a reprap prusa mendel with wade extruder ... fairly wide nozzle and I'm extruding 3mm translucent pla. It seemed every one else's settings didn't put out enough material and the parts looked horrible. This might be too much, but it's a start anyhow!

@unexpectedly

Looking at your Speed settings make me think you have your E_steps_per_mm set wrong.

I run my machine with skeinforges feedrate and flowrate equal but it does require having the E_steps_per_mm set perfectly.

So instead of changing the flow rate in skeinforge to get it right change the E_steps_per_mm in the firmware until you have it correct.

@subline : Thanks for your help. This is a setting I wasn't yet aware of... Once I'm done with the project I'm printing at the moment, I'll work on the settings so I have things set up properly. And also share this info with the guy helping me so he'll know where we both went wrong.

Thanks!
Chris

Cheers everyone,
I've been sick for the past two weeks, I hope try out your suggestions this week.

@unexpectedly
It looks like you have your setting off by about 30 times. So start by dividing your E_steps_per_mm by 30.

Are you using Inches in your models and/or Skeinforge by any chance?

@ unexpectedly

Actually now that I read back a bit I see that some of you are using SF40 which uses feed stock input vs. extruded length output for 39 and earlier. Which could be the cause for your issue in the first place. A circle of 3mm has a surface area of 7.069 which is 29.702 times larger than than 0.238 which is the surface area of a 0.55mm circle. Sounds awfully close to the 500 extrude rate over 16 feedrate that you're using. Which works out to 31.25 faster extrude than feed.

Grogyan have you checked your limits and endstops? And please be more specific about question...
I am pretty sure that Skeinfoge did not decide anything but there was something else....

I will be trying the new flow rate as soon as the new firmware gets fixed, previous version stopped printing after a few layers and crashed, an old bug.

For me the new flow rate should be about 75.24 e steps per mm

Months ago, theses two topic helped me a lot to get started with skeinforge :

Setting up Skeinforge for the first time

Skeinforge 40 setup notes

and just in case that can be useful to someone (even if a profile is quite machine-specific), I putted all my settings in a google spreadhseet :

[docs.google.com];

Can someone please tell me which setting in skeinforge determines the initial travel speed of the print head? i.e. when I start a print, the print head just crawls to the start position determined by 'multiple' at, in my case, 60mm/min when I would like it to make the movement at a speed of at least 760mm/min. The rest of the print goes at a reasonable speed of about 1300mm/min.

Thanks, Ian

Check the limit plug-in. Skeinforge may be trying to limit the speed of a largish move incorrectly.

Thanks Jim, I found another post eventually which pointed me to the Z limit being too low - changing it solved the problem.

Hello, I just played with skeinforge, worked properly once, I modified some parameters (carving/milling if I remember), and now I get an ugly python error (opening the test.stl file bundled) : "AttributeError: LoopLayer instance has no attribute 'segmentTable'" (full log in joined file)

Assuming my tests were inconsistent, I erased the skeinforge folder, and redeployed the archive, but then I get the same error. So I think settings are saved somewhere else, but I can't find where.

Any idea ? (I use windows 7)

Hi,

here is one that works fine with my mendel prusa with wade and .5 nozzle.
I tried the settings I found under the ultimachine link above but had to change the extruder settings to work. I also changes the start and end sequence to the same code that slic3r generates and added that useful skirt.

HF!

This is also posted as a seperate thread. So if any discussion please post there...
Hi All,
yes long time no hear from me
I have done some research on the "stretch" plugin today and it is actually working quite well.
The naming is "Skeinforge traditional" impossible to understand of course....
So here the settings and what they accomplish...
Increase:
Cross Limit Distance over Perimeter width(ratio) Decrease: Decreases the diameter of innermost perimeter, also adjusting the loops. Extreme (over defaults range) Increase: Pushes outer loops out, does not effect outer perimeter.
Loop Stretch Over Perimeter Width(Ratio) Decrease: Moves the inner loops closer to the inner perimeter not effecting the inner perimeter itself. Increase: Moves the inner loops away from the inner perimeter not effecting the inner perimeter itself.
Path Stretch Over Perimeter Width(ratio) Decrease: 0 is default and minimum. Having to increase this value means probably that you have some miscalibration..) Increase: Extends the fill lines onto the inner loops. (For fixing disjoined inner fill)

Perimeter Inside Stretch over Perimeter Width (ratio) Decrease: Decreases the effect of the increase in diameter of the inner perimeter. (loops not effected) Increase: Increases the effect of the increase in diameter of the inner perimeter. (loops not effected)
Perimeter Outside Stretch over Perimeter Width (ratio) Decrease: Leave at default. Dont really know what this is a fix for. Increase: Creates a slow increase of extrusion flow along the first path. Pulls the startpoint outwards a slight bit.

Stretch from Distance Over Perimeter Width (ratio) Decrease: moves the effect of the increase in diameter towards smaller holes. (Loops affected) Increase: moves the effect of the increase in diameter towards bigger holes.(Loops affected)

Obviously I advise to use SFACT that is easier to use than Skeinforge.

Hello,

Im starting to learn skeinforge in repetier host, I have been through a setup guide and got it to print. Now Im stuck trying to add support.



What is this? how can I remove it? Ive tried "everyting" but with no success... Looks like skirt, but skirt is deactivated.

Any suggestions are appreciated!

It was cooling. I changed "cool type" and now its ok

Hi, I might just seem dull here, but I was wondering, where exactly is the Profiles Folder in Skeinforge, that you said you'd gather the settings into?

Thank you all.

Peace out!

at your Userprofile there is a hidden folder called ".skeinforge"

This is a thread for people to post your skeinforge settings and your skeinforge scripts. Every once in a while I will gather the posted settings and put them into the profiles folder in skeinforge.
