Axis barely moving when using Skeinforge, ok with slic3r
October 11, 2012 01:44PM
I have been slicing using slic3r for a while and everything works ok there. Wanted to give a shot to Skeinforge but I cant figure out why, when I print gcode generated using it, the axis are moving EXTREMELY slowly.

I have no clue what is going on, tried to read a few tutorials looked at the settings in every tabs and I just cant figure it out.

Can someone help please?

Start with the basic stuff configured
1. Enable all of the following: Alteration, Carve, Chamber (If you have a heated bed), Comb, Dimension, Export, Fill, Home, Inset, Preface, Skirt, Speed, Temperature

2. Optionally, enable Bottom, Cool, Jitter, Multiply, and Raft, if you need those.

3. Your problem is likely in Dimention not being enabled, or SPEED being set incorrectly.

For Dimension: Enable. Absolute. Extruder Retraction Speed 13.3, Filament Dia. 3.0 (or what ever you measure), Filament Packing Density 1.0, the rest defaults.

For Speed: Activate Speed, Add Flow Rate, Bridge Feed, and Flow both 1.0, Duty Cycle Beg. 1.0, End 0.0,

FEED RATE 30.0
FLOWRATE 30.0

Object First layer ... All should be 0.4

Travel Feed Rate 30.0 - 50.0 Depends.

Be sure Limit is disabled.

Thank you very much for your input, I did configure some basics in there, followed a guide but it would seem its incomplete. I did have 25mm set as the feed rate, tought that would have taken care of the stepper speed.

I will verify all this tonight.

Thanks again.

Well, things look much better now thanks to you!

Just one thing I cant figure out, whenever I start a print the extruder reverses and ejects the filament. Doesnt makes sense to me, here is the begining of my gcode.

Any idea?

You should add:
G92 E0           ;Zero the extruded length
to your startup code.

Man I looked everywhere for that info! I read it somewhere a while ago when I was planning on building my printer and now couldn't find it.

Thank you very much!
