Replikeo Prusa i3

Hi Guys,

I've just assembled my replikeo, but i've some problems, I'm using pronterface, to check everything. for now only X axis works without any problem.

The Z and Y Axis makes a lot of noise when I click the home button. With small steps, it works ok.
I've already check the endstops with a multimeter, It seems OK.

configuration.h attached and also the video below:

any suggestions?
Thanks in advance.

I had same problem with X and Y, just change your configuration, try to invert the motor rotation...

#define INVERT_Y_DIR false   // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR false   // for Mendel set to false, for Orca set to true

The mine is so, and that's ok:

#define INVERT_X_DIR true    // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false    // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR true     // for Mendel set to false, for Orca set to true

No.
I've already changed it and it does the same, but on the opposite side. :\

Ok the Y axis endstoper its Ok
Bad wiring, I need to connect it correctly, like in this link: [forums.reprap.org]
because it is a Y-max position.


But the z axis still make a lot of noise when I press "home", and it only stops if I press manually the end stopper, and it adjusts it self, like 1cm down (like if it really touch on the sensor)

my power supply is an S-400-12, and its giving me 12.2v I've tried to adjust it to 12.4v, but nothing have changed...

Ok .. my bad, sorry for didn't search it before.

It's a acceleration/jerk problems..

I've changed this values based in this post: [forums.reprap.org]

#define HOMING_FEEDRATE {3000, 3000, 100, 0}

#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4100,650}
#define DEFAULT_MAX_FEEDRATE {120, 120, 2.5, 50}
#define DEFAULT_MAX_ACCELERATION {120,120,5,800}

#define DEFAULT_ACCELERATION 50
#define DEFAULT_RETRACT_ACCELERATION 50

#define DEFAULT_XYJERK 20 // (mm/sec)
#define DEFAULT_ZJERK 1 // (mm/sec)
#define DEFAULT_EJERK 20 // (mm/sec)


I'll make some tests, and then post it where.

thank you

This is my first print.

It broke when I tried to remove from the glass.

I definitely need to calibrate it, any suggestions for where start?

Thank you

Is it normal if the extruder moves? I can easy move it with hand..
sometimes the extruder moves it self.. just printing a simples cube (image attached above)

thanks

It actually balance!

see the pictures attached, and compare.

I also will change the bed, because is one (fiber) isn't 100% flat, I'll use glass instead. (the z axis end stoper is Ok in all corners, but in the middle it touch)

temperatures:
bed: 102c
extruder: 230c


thankyou

I put the 2 screws, but isn't enough, it balance alone when is printing.

Does anyone had this problem?

Thanks for helping
