Topic: Centering objects on bed?

I notice when RH loads an object to print, it has it in the center of its 3D view of the bed, but on my actual solidoodle bed, the object is much closer to the right hand side of the bed (become obvious when printing wide objects and the skirt runs off the edge :-).

I can manually move the objects in RH, but is there a better way to fix this? Is the bed geometry defined in the printer definition in RH?

Re: Centering objects on bed?

That line about "if supported by firmware" bothers me :-). Certainly the endstop switches aren't going to move, so when it homes X and Y it will still have the head in the same physical location as always. Maybe I'm just overthinking things and should just try making some changes and see what happens...

Re: Centering objects on bed?

Think about it this way it is all backwards.  At the endstop it is at 200 not Zero.  So just move for example the X starting from the end stop toward the left and count mm's as you move across till it either stops or hits something.  if it just stops then X needs to be a larger number.  If it hits something then X needs to be a smaller number.  If the bed is 200 mm's then when X is against the stop the nozzle should be perfectly in line with the right edge of the bed.  RH should show 200mm's  when you move it to the left it should reduce the number to zero.  At which point the nozzle should be perfectly in line with the left edge of the bed.

Re: Centering objects on bed?

I have found a work around for my problem. On sli3r settings/extruder tab, I changed the Extruder offset to 50.Even tho it shows off the bed in RH/gcode tab  it now prints about center.

SD3, E3D hotend,linear bearing on x/y axis',pillow block bearing on y conneting rod, ball bearngs on front y axis, fan on y stepper motor.
