all axis only move in negative direction (to the home)

[nima]

Hello

I have bought the i3c (dual extruder) Order NO:20150425133354237 Order Time:2015-04-25 13:33:54
x and y can only go home and they are not moving the opposite side, they don't even puls
z is trying to go home but it moves really hard and seems stiff, I tried to lubricate the threaded rod and the z axis nuts but did not help, for moving to the opposite side it don't even puls,

didn't try the extruders yet

How do you connect the endstops? Could you please take a picture of mainboad , and different angles of printer, let me see the color of wires connected to endstops.

Hello,
I am not home to take pictures right now, but my board is exactly the same board as is shown on the manual and I have connected the end stops the same way as it is shown in this manual step 5

The Z axis is moving fine now, one of the rods threads is damaged and have a dent in it and that was causing the issue, I will talk with the customer service regarding that and some other broken parts later, I will avoid that part of the rod for now Until resolving the one direction movement issue,

I moved all of the end stops from their current position which are labeled as x-min, y-min, z-min to x-max, y-max, z-max and noticed that now I have movement in both direction but when I click home each axis goes to the opposite direction of end stop and obviously when it reaches the end it does not stop until I restart the printer,
also I noticed that with this configuration I have the option to move all 3 axis from the lcd while with the original configuration I only had the option to move x and y,
I moved the end stop connections back to the original configuration for now.

Endstops should be connected to X-MIN, Y-MIN,Z-MIN.
Please check if the wires are well plugged.

[nima]

yes, as you can see in the picture they are connected properly and working, I made sure bye pressing each one while the motor was rotating and it stopped the motor.

[nima]

also any idea why I only have movement control for x and y through the LCD ?
prepare>move axis>move 1mm>move X/Y
I don't have Move Z when the end stops are connected to z-min but I had it when I tried and conected the end stops to max!

[zhangxueyou]

Even after uploading the firmware I sent you, all the axes can not move normally when z endstop connected to z-min?

[nima]

Oh I dint know that's you who emailed me the firmware as I asked for it in another topic I thought that is the same firmware I already have on my board.
I will install the firmware and update you with the result.
thanks

I uploaded the firmware and nothing was changed and the movement were the same,
I changed the following parameters in the file configuration.h from false to true

const bool X_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Y_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.
const bool Z_MAX_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop.

now the x and y axis are moving fine but I still don't have the option to move the z axis from the display!
