Hi
When i started my first print i had the dot in the lower left corner of the printbed (in the repetier software) and i placed the object to be orinted near the center of the printbed.
When the printjob started the printhead ran to the upper left corner and “crashed” before i could stop the job.
I have tried to move the object and the dot in repetier software, but it keep going to the upper left corner.
Anyone knows what can I do to fix this?

either your endstops are not wired correctly, or your pulleys are not installed correctly so they interfere with head movement.
check if you can move the head manually via repetier host and check if endstops are working. you should not be able to let the printhead crash.
If you reloaded the firmware you need to use Arduino 1.0.6 or lower.
You can download it from here.

I noticed that the guide rails are not perfectly parallell. If the motors have to struggle to hard they will get “lost”, is that correct?
So if I try to get the printhead to move more easily, by aligning the guide rails better, the problem might go away?
This is very true.
Look in this link.

Thank you! This will be very helpful!
Hi guys!
The Vertex project has been “on ice” for a while, but now I have done the XY-alignment and the print head can move freely without any resistance. The printer still won’t function as it should!
What else can I do? Could it be the Z-axis that is the problem? If it is, how can I fix it? Seems much more difficult than aligning the X and Y.
What exactly is not running as it should?
For a first analysis remove the printer from all communication and use the build-in menu:
If this is doing well you should try the build-in movement menu: 1mm steps in each axis.
If this is fine, you can reconnect your computer and do the same with the repetier software.
There are a lot of possibilities for errors, the better your description, the better the proposals for overcoming these effects.

All the things you mentioned are working fine. The problem is that when the printjob starts the machine starts to build the part at the wrong position at the build plate.
It makes about 15 parallell lines, which I thought would be the raft, but then it starts to build the part. The problem is that it only moves maximum 1 mm in the Y direction, ca 40 mm in X direction and 0 mm in Z direction. The part is the Vertex logo, as a test. So the last of the 15 lines becomes a big loaf of clogged plastic.
I will give it another try tomorrow and take a couple of pictures.
The motors are working (I can run them from the ‘move axis’ menu). I have tried to upload the software for the printer a couple of times.
I really don’t know what to do.
So if you can move 200mm in x, y and z directions by the firmware menu, then I would propose to check the repetier settings. You may post the gcode generated by the slicer to be reviewed.
However, check this forum for proper settings for Repetier host (I cannot help, I’m using slic3r).
