If you are new to 3D printing, this might help, as I break down everything you need to know about these two popular filaments. By the way, which is your favorite?
 
Trying to decide between ABS and PLA filament is not always easy, as both come with their own specific qualities. What's your favorite? Let us know!

Filament is a fundamental material in 3D printing. The two most common are ABS and PLA. This article compares ABS vs PLA to see which one is right for you.

I have a TwoUp with a Printrboard Rev. D.  My x driver is messed up and a new board is on its way.
My question is...Can I turn off the Allegro A4982 driver for the x axis in marlin and switch and run the x axis with the Extruder Allegro A4982 driver?? Down the road I want to build a delta with a ceramic extruder using air and I wont need an extruder driver.

In Arduino under Marlin.h if found something like this.....

void manage_inactivity();

#if defined(DUAL_X_CARRIAGE) && defined(X_ENABLE_PIN) && X_ENABLE_PIN > -1 \
    && defined(X2_ENABLE_PIN) && X2_ENABLE_PIN > -1
  #define  enable_x() do { WRITE(X_ENABLE_PIN, X_ENABLE_ON); WRITE(X2_ENABLE_PIN, X_ENABLE_ON); } while (0)
  #define disable_x() do { WRITE(X_ENABLE_PIN,!X_ENABLE_ON); WRITE(X2_ENABLE_PIN,!X_ENABLE_ON); axis_known_position[X_AXIS] = false; } while (0)
#elif defined(X_ENABLE_PIN) && X_ENABLE_PIN > -1
  #define  enable_x() WRITE(X_ENABLE_PIN, X_ENABLE_ON)
  #define disable_x() { WRITE(X_ENABLE_PIN,!X_ENABLE_ON); axis_known_position[X_AXIS] = false; }
#else
  #define enable_x() ;
  #define disable_x() ;
#endif

#if defined(Y_ENABLE_PIN) && Y_ENABLE_PIN > -1

    #define disable_y() { WRITE(Y_ENABLE_PIN,!Y_ENABLE_ON); WRITE(Y2_ENABLE_PIN, !Y_ENABLE_ON); axis_known_position[Y_AXIS] = false; }
  #else
    #define  enable_y() WRITE(Y_ENABLE_PIN, Y_ENABLE_ON)
    #define disable_y() { WRITE(Y_ENABLE_PIN,!Y_ENABLE_ON); axis_known_position[Y_AXIS] = false; }
  #endif
#else
  #define enable_y() ;
  #define disable_y() ;
#endif

#if defined(Z_ENABLE_PIN) && Z_ENABLE_PIN > -1
  #ifdef Z_DUAL_STEPPER_DRIVERS
    #define  enable_z() { WRITE(Z_ENABLE_PIN, Z_ENABLE_ON); WRITE(Z2_ENABLE_PIN, Z_ENABLE_ON); }
    #define disable_z() { WRITE(Z_ENABLE_PIN,!Z_ENABLE_ON); WRITE(Z2_ENABLE_PIN,!Z_ENABLE_ON); axis_known_position[Z_AXIS] = false; }
  #else
    #define  enable_z() WRITE(Z_ENABLE_PIN, Z_ENABLE_ON)
    #define disable_z() { WRITE(Z_ENABLE_PIN,!Z_ENABLE_ON); axis_known_position[Z_AXIS] = false; }
  #endif
#else
  #define enable_z() ;
  #define disable_z() ;
#endif

#if defined(E0_ENABLE_PIN) && (E0_ENABLE_PIN > -1)
  #define enable_e0() WRITE(E0_ENABLE_PIN, E_ENABLE_ON)
  #define disable_e0() WRITE(E0_ENABLE_PIN,!E_ENABLE_ON)
#else
  #define enable_e0()  /* nothing */
  #define disable_e0() /* nothing */
#endif

#if (EXTRUDERS > 1) && defined(E1_ENABLE_PIN) && (E1_ENABLE_PIN > -1)
  #define enable_e1() WRITE(E1_ENABLE_PIN, E_ENABLE_ON)
  #define disable_e1() WRITE(E1_ENABLE_PIN,!E_ENABLE_ON)
#else
  #define enable_e1()  /* nothing */
  #define disable_e1() /* nothing */
#endif

#if (EXTRUDERS > 2) && defined(E2_ENABLE_PIN) && (E2_ENABLE_PIN > -1)
  #define enable_e2() WRITE(E2_ENABLE_PIN, E_ENABLE_ON)
  #define disable_e2() WRITE(E2_ENABLE_PIN,!E_ENABLE_ON)
#else
  #define enable_e2()  /* nothing */
  #define disable_e2() /* nothing */
#endif


enum AxisEnum {X_AXIS=0, Y_AXIS=1, Z_AXIS=2, E_AXIS=3};
 
-------------Can this or maybe some other setting in Marlin be changed so that the two (x and eo) be swapped??  I wont need an extruder!

Hey guys,

As 3D Hubs has reached 20,000 printers on the platform we wanted to show you who is actually behind that number and we asked our Hubs to share their printing stations.

You can find the entries under ‪#‎WeAre20k‬ on all the social channels (mainly twitter and Instagram) and here's the album of the winners so far. Still 16 days to go wink emoticon Just curious if you have anything to share as well?

I bet that is why the bottom is rotated 180 degrees from the top. A couple of other things. For multi degrees if freedom you'd want six steppers on one side, top or bottom, each one driving one of the six struts, like one of those big flight simulators. Put that on the bottom, only, to remove gravity from the support problem añd you might have something. The tool path generator will be interesting. A slicer would no longer be sufficient.

Snorkel holder broke mid-summer! Design, slicing and printing took about 2 hours total and problem fixed. Sliced with Slic3r 1.2.9 at 0.3 layer height  and printed with ABS. Unfortunately I didn't have matching color, so I printed in Natural ABS. I will print another one when I get some black. I have to say I enjoyed flexibility that ABS offers (PLA is way too brittle), it was needed for this design, as the holder has to stretch a bit before clamping into position.

Wife is happy as well that I finally printed something useful :)

A few days ago I've asked for a marlin modification to drive a remote extruder on a CoreXY printer setup. So the firmware is still a question, but  this is my approach for a CoreXYE driven printer. All 3 belts are in a seperate layer in this concept. So basically there is no real belt crossover.
CoreXYE means basically a more or less traditional CoreXY belt system with a remote driven extruder.
This is the result of a short discussion I had with Nicholas Seward who made the sketch of the first CorEXY system I've seen. (Thanks that I can use your original picture for the comparison!).

In this discussion he mentioned that we will probably see some side forces on the X carriage due to the E belt. I've tried to compensate this in this sketch.
The good news is, that we probably have the possibility to drive the filament from 2 sides at the same time. The bad news is that this will be a really complex setup ;)

Maybe this approach can equalize the forces on the extruder carriage. But unfortunately it will add some torque to the extruder carriage (less problematic I think) and the same tilting problem on the Y axis that the H-Bot concept had.

I also made a quick and dirty 3D sketch of how a dual drive for the filament could look like for this approach.

Any ideas/suggestion?

The main problem I want to solve is that you can't print the rolls. Every dimensioning or roundness failure would directly lead to a multiplied failure in your print. But I think there are ways to solve this. 

And Btw, you will also get failures in your print when the dyneema or fishing line moves the roll up and down ;)

This weekend I made great progress on upgrading my #FelixPrinter with a #SmoothieBoard 4C. I remixed the great design of the hot end holder base by +Michel Satoer and added a mounting point for a 8mm inductive sensor as a bed probe. The picture shows the first try, where the holder was a little bit to short. Currently it is printing the improved version which should also be the final design. The last picture shows the temporary mounted HAL end-stops which I glued with a hot glue gun to the frame.

The improved #E3Dv6 base can be downloaded from my github repo:

No, it's just a heavily modified Felix 3.0 from http://www.felixprinters.com. Mods so far: +Michel Satoer 's E3Dv6 hot end holder, inductive bed probe, HAL end-stopps +Martin Bondéus #BontechExtruder, a 4ch SmoothieBoard, a Bicker BEO-3624 PSU and a PEI coated aluminum heated bed with a high power 180W Kapton heater. The base of the bed is for a Prusa i3 I guess.

Hey guys..maybe someone can help me with this...

I went to Thingiverse and downloaded this file: http://www.thingiverse.com/thing:903411/#instructions

Right now I have DaVinci 1.0 FLASH with Repetier.
I am using Sli3er for the job.....but the print stops at about 15% of the job and when I see the progress bar in the lower right of Repetier it says 100% printed.
Can someone help.

Thanks!!

Hi everybody, so I have been looking for a low price 3d printer for awhile and was wondering if anyone here has used the HobbyKing Mini Fabrikator, its just under $180 which is by far the cheapest I've seen, but I would like to know if the quality is going to match the price

To be fair, the designer's goal is to put one 3d printer on every desk of a class, so that it could capture attention of every children. With your suggestion, 2/3 children need to share a printer on the same budget.

I think there is a market for cheap learner printer. Many purchase a $300 kit lack the skill to assemble and end up with an expensive paper weight. This is much better value than a makibox clearance unit, which someone is still picking up.

For those who get a 3d printer, but later found no 3d object to print and don't like learning 3d CAD, this is much smaller initial cost to try the water.

I think the build quality is going to make or break this product. Let's hope HobbyKing could keep the rods & threaded rod straight. Even if they ship a crappy hotend, it is easy to swap in an E3D lite6.
