X Y Homing position not working

[DQW]

Hello,

In Repertier or Prontrun you can set you're homing position to start printing.

I'm not able to succeed in this. The extruder goes to my endstop and my printbed also goes to my endstop.
But my extruder isn't above the printbed anymore then. It's hanging in free air and performs print tasks just in front of the bed.

I tried all position changes tot -100 x and -100 y but nothing changes only thing I can change is the Parking position.

I can't find anything or anybody who has the same problem.

have you tried the printer settings here?

[DQW]

Yep changed it in various ways. It keeps homing to the same position.

how about check the calibration here in the Final Polish: Bed Centerpart:

Whatever I change, the printer still goes to the same wrong spot when homing in.

I changed every setting in repertier or printrun and I also changed the code. But it keeps on going in the same spot.

I think I have to alter something in the source code but I don't know what exactly.

Hope anybody knows what to do, trying for a week already with no results.

werid..Are all your axis homing correct?

[DQW]

So far the z-axis homes correct to the end stop also the x axis is correct it homes to the end stop.

For the y axis its homes to the end stop but it should go to the center.

[Mark]

nope, the Y axis should home to the endstop too, the endstop position is the original position.

So that means that my printer non treaded rods are to long and should be shorter?

[Mark]

how long are your smooth rods? and do you have a picture or video when homing here?
