help, printing off bed

I have been trying to print a stand for my ps4, it is in 2 parts and I arranged it in slic3r so it fits well within the print dimensions but when I start the print it starts halfway across the bed resulting in some of it printing off the bed. Can somebody tell me what I'm doing wrong? any help would be much appreciated

It's very hard to say what went wrong without seeing your STL and gcode files. I assume you homed all the axes before starting the print?

Thanks for the reply. Yes I went through the same procedure as I normally do, this is the first large object I have tried to print though so I'm using more of the bed, It just keeps printing off to one side. I'll see if I can get the files uploaded.

This is the STL I downloaded from thingiverse and the first part of the G-code I generated in slic3r.

That gcode looks ok to me, it prints from X49 to X174 and from Y13 to Y186. Those ranges should be on the bed. However, for large prints in the X-direction, bear in mind that the centre of the bed isn't at X=100, it's more like X=120 depending on your build. So you should measure where it is and put that in the slic3r Printer->Bed centre setting.

Ok thanks, I'll have a look

the print centre in slic3r is set at X100 Y100, looks like this is the problem. thanks for your help, I've been scratching my head over this for a couple of hours now

Cura does not allow changes to the bed center position, so I run a small G file as follows:

G1 X112 Y91.4
G92 X90 Y0

Substitute your actual bed center for the X & Y values. My Y position is off because I moved my Z pillar to provide more clearance between the fan backwash deflector and the Duet enclosure (it still reaches the edge of the bed OK).

When slicing large prints, don't forget to change the "skirt" parameters so that it does not attempt to print the skirt off the bed.
