I need a calibration skeinforge

Postby miguelvmonroy » 2015-Mar-Sat-17-Mar

Hi friends, i am new.
And i have a lot of Questions, but my First post, is about of my 3d print +LC .

My problem is when i want to print my .stl (pronteface) the printer is moving Perfectly, but the result is very bad.

Any now about what i need mybe is calibration in skeinforge ?

this is the link of my parts.

What model printer do you have? There is a reference to "+LC" in your post, but that's a fairly old model of Printrbot. If that is the model you have, then it probably is not new; it was probably used by someone else before. Is it possible for you to talk to the original owner? Was the printer making good prints before?

The majority of people with Printrbots seem to be using Slic3r or Cura instead of Skeinforge to do their slicing. These are all free programs.

Calibration of the printer is one issue, involving things like steps per millimeter on each axis. Setup of the slicing program with the right values is another issue, involving things like extrusion temperature, speed of motion when extruding, etc. etc.

This is my model print

Printrbot Plus 1303

Hi I have this version of Printrun 2014.08.01 that has these two
pronterface skeinforge.

It has never done a good impresión, that cube was the only thing I think it printed well.

I have already calibrated the printer with a vernier, the data in (mm) are in the formula below in each axis. To calibrate it,

I used scilab and this formula for the axis and extrude (X.Y.Z,E).

First I declared a variable called “N” ad then

I used this formula:
N= X N=N*100/X
N=N*100/Y
N=N*100/Z
N=N*100/E
and the result of each N was put into the code line.

float axis_steps_per_unit[] = {63.93,63.695,2281.7905,731.24};

I haven’t configured slicing, what should I do?

I hpe you can help me, thanks.

I've had the best results with Simplify3D, but it's not free.

Aside from that, you can find a lot of great info here when working with skeinforge.

Skeinforge is both old and slow, so start with either slic3r or Cura, both of which are both widely used and free.

Repetier-Host is more popular than Pronterface/Printrun, and includes Cura and Slic3r. If you're just (re)starting it's your best choice, free, and regularly updated. Worry about other choices once you become good at printing.

Try the forums on reprap.org, maybe someone there can help you. There's very little reference to skeinforge in this forum, and very few people here have used it. It has very complicated settings and is very difficult to make work. Skeinforge is not for beginners.

I recommend you try cura or slic3r. Once you have it working well with either one then try skeinforge if you still want to.

I think you made a bad choice with skeinforge, but you can fix it!

ABS adhesion problems likely have nothing to do with which slicing program you're using. Have you ever printed PLA successfully? It's easier to print.

First, make sure your print surface is the same distance from the extruder head everywhere. For unknown reasons it's called "leveling" your printbed, but it has nothing to do with a spirit level. It's been described many times in this forum, but basically move the extruder around to find the highest corner, adjust it until you can put a piece of copier paper under it so it has a slight drag (resistance to pulling it out), then move to all the corners in a circle and adjust them so you have the same drag at every corner. It will take several trips around since adjusting one corner might affect the others.

Move the extruder to the center of the bed. Adjust the Z homing switch (also falsely known as an "end stop") until you have the same drag after clicking the Z home icon. It'll stake several tries, and you may want to start with the extruder high to avoid digging into the bed.

You need something to help the plastic stick to your print surface (and what is that? Window glass is often used since it's very flat). A lot of us use Elmer's Washable School Glue Stick, but any similar product should work. Washable is best since you can wash it off when you're done. Search the forum, everything from "abs glue" to sugar water, hairspray, and a lot of other things have been used. Blue tape might work if you're lucky, but probably not.

Make sure that your heated bed is hot. ABS need 100 to 110 C to stick.

And make sure that your filament has been accurately measured and entered in your slicing program. Try the above one step at a time. Ask questions, and post pictures, if you need help. You can attach pictures to your post, but may not be able in include links to other sites yet.

Glad to hear it's working. Did you also adjust your Z home position (and/or Z offset if you have one of the probe models) to improve the bed adhesion?

Getting the plastic to stick takes the right Z home settings (it has to be close enough so the first layer is pushed into the bed, but not so close the extruder won't work), the right bed temperature (ABS like it hot, 100 to 110C), and the right extruder temperature so the plastic is melted properly, but not so hot it burns or doesn't cool enough to become solid. You don't need a fan with ABS, either.

Getting everything right the first time can be hard, lots of things to get the right settings for, and it looks like you don't have anybody in your area to help out. Congratulations! Too many new users just give up. It'll get easier.

hi
i have this problem right now.
but in this web page they mention about this problem
http://reprap.org/wiki/Print_Troubleshooting_Pictorial_Guide
http://forums.reprap.org/read.php?262,205774

in my steppers motors, i have this
Z= 600 mA

in this part he mention @Andrew Smith

Skipping steps. A little more current to the stepper motors is the simplest fix in most cases.

but i don't understand.


this is my print right now

plis help me

thanks a lot

Those current settings, if accurate, are very low. The motors are, from memory, somewhere between 1500ma and 2000ma. How are you measuring the current; I'm not familiar with how it's checked on a RAMPS board. Low motor currents will make the motors miss steps and lose position. Increase them to the middle of their range and try again.

Move the carriage and print bed with the power off, and make sure that they move smoothly and don't get stuck anywhere. You might need some light machine oil on the linear rods if that happens.

It's popular to encourage setting the motor currents as low as you can, but they can safely run at their rated limits. If the motors aren't becoming hot then they're good and you can try to lower the settings later if you want. A good test is to see if you can touch them for 10 seconds before they become uncomfortable.

Make sure all the setscrews on the motor pulleys are tight, and that a setscrew is on the motor flat.

You might have your extruder temperature too high, try turning it down 5 to 10 degrees and see if the melted areas improve. But you should only work on one problem at a time, so start with the layer shifting first.
