Print is not centered on print bed

[basteluwe 1]

Hi guys,

when I load #.stl files into Cura they appear right at the center of Curas print bed, but when I start real printing, there is an offset from center of my Ultimaker Original. For big prints there is a risk of going outside the printable area.

How to correct that, i.e. synchronize center of print-bed for both, Cura and UMO?

Regards Uwe

How big of an offset are we talking about?

 

In the Machine Settings, is the "Origin at center" box ticked? It should NOT be ticked.

Hi there, thanks for answering.

 

The offset is for the X-Axis: 10 mm to the right, Y-Axis: 2.5 mm to the back (about).

Yes, the checkbox "Origin at center" is un-checked (empty).

 

BUT: I just got an idea, what could have caused the offset. Some time ago I checked the accuracy of measures of my prints and found them slightly to small. So I increased the "Steps per Unit" for all axis.

Original values were: M92 X78.74 Y78.74 Z200.00 E836.00

New values are: M92 X79.38 Y79.86 Z200.00 E854.00

 

I guess by changing the "Steps per Unit" I have messed with the center-position as well, right?

That (horizontal)_ offset is "by design" and should not affect printing larger models. The offset is there because the nozzle is not in the middle of the printhead.

OK, Thanks!
