Common issues :wrong motor direction，Endstop hit...

[William]

Hi,Could you take a video showing more details about the noise?

Hi,
This is my video : https://www.youtube.com/watch?v=_b0H6pvgNQY
You can hear the Z-axis grinding and the X-axis clicking.
Maybe the pololu of X-axis must be reconfigured?

Hi,as to the noise issue,I think you need to make sure with a caliber that both sides of Z axis are at the same height.Please check this post for more details.http://www.geeetech.com/forum/viewtopic ... 917(thanks.

Thanks for this post, i'm able to print in decent quality after a long but nice building phase
I still have an issue why my Prusa I3 B and i can't figure out how to configure my firmware: configuration.h
All my print are mirrored in Y axis, moreover, i need to flip X and Y in repetier interface to manipulate easily the printer in manual mode.
Could give me some clues ?
I try to change some boleans like "INVERT_X_DIR" but's no longer possible to homing after theses changes.

After a double check on my side, i figured out that X and Y axis are flipped out (steppers motor and endstop detector) ...
The 2 problems have to be linked somehow. I start a unsymetric print to validate this solution...

Problem fixed !

Here are some details about the ways of configuration according to your need.I hope it will help you.

hello I am having an issue when homing my printer. all of the motors are going in the correct direction,
the Z axis homes properly with the endstop, but then either the Y or X axis (whichever one makes it to the endstop first)
will just make a horrible sound pressing up against the endstop as if it is not there. I try using the endstop from Z(because work just fine) at X and Y to test if it the endstop itself, but i have the same result(horrible sound pressing up against the endstop as if it is not there)
I followed all of the directions for wiring and I have tried changing endstop functionality in the firmware,
but nothing seems to work. What im missing ?

You can send M119 code and you can confirm that Endstop is intact via analyzing its return value
You should also ensure the wiring of Endstop is correct

Interesting, I also have a similar issue.

When I click the X home button in Repetier, the printhead moves to the home position and keeps hammering at it. I have to do an emergency stop - it's as if it's trying to go past the endstop. If left unattended, it'll eventually stop after about 10-15 seconds.

Yet when I use the directional arrows to move the printhead along the x-axis, it gets to the endstop and respects it - that is, when it gets to the endstop, it acknowledges "endstops hit: X" on the LCD and doesn't keep pushing - it stops like it's supposed to.

I have swapped out the endstop microswitch for a brand new one and also tried swapping it with the y-axis endstop. Same problem. Brand new I3 A Pro. See video here: https://youtu.be/IMTEOb7thPk

SOLVED: Poor QA in the factory. Motherboard on the top right hand side was shoved through the standoff/insert, result being that the X-endstop was shorting out on the standoff/insert. Disappointed but resolved.
