Hello,
I have a problem when printing large objects.
My printer is anounced to can print Objects up to 200 x 200 mm.
I wanted to print some letters and the size of the object ist aprox. 170mm in width, see picture 1 which was taken from the screen from repetierHost 1.6.0. ther is everything inside. Then I slice it with slic3r -Slic3r-1.38.4-prusa3d-win64-full - see picture 2 . After that return to RepetierHost - see picture 3. And when printing the object the last "n" in the first line causes some trouble when printed and the head ist rising up for a few centimeters and the Object ist missbuild.
Please give me a advice where I can / should change parameters or use another version of which software - in this case please tell me where to find / download.
Thanks in advance.

Hi,
Maybe you can move the model or reduce the scale?
As shown in the picture, the size can be adjusted

Hello,
in the meantime I have installed the newest Version of Repetier-Host (2.1.6) and with this the slic3r 1.3.1 on a laptop.
In the printer-settings - Bed shape the size of 200 x 200 mm.
When the printhead ist at home-Position, it needs to got to x 24 to be at the left starting position on the bed.
I have left the Origin for x and y to zero.

If I now start printing an object with max. x=180mm then the printer starts with the skirt which is set 2mm distance from object. It goes at y= on the bed for aprox. 180mm from x=home then lifts the head 0.25 mm (one layer) higher, goes to y = 180mm, goes then to x=0 which is 24mm beside the bed and there it comes to y=0 again.
There are 2 problems: the first is where to set the distance between x home and the left boarder of the bed which are approx. 24mm. I tried to set the Origin x to 24 which changed nothing when printing.
the second problem ist the lifting of the head when reached 180mm = the max. x-size of the object.
Please can anyboy tell me where to change the settings, so I can use then max. width of the bed with 200 x 200 mm and the complete printing to land on the bed.

The advice with adjusting the size I tried - if I go to scale to Maximum - the Object changes to 200 x 200 mm size. But this is not what I want. I only want to print the size of 180mm because the size of the letters shall be in that way.
If you can give me an advice what to fill in the right parameters for 200x200 mm bed and the "starting gap of x" with 24 mm, I hope then it would work.

Thanks for any advice.
I will start with testing again on next Wednsday.

Hello, I did some add. testing - the problem (second) of lifting the printhead in the right area is solved, the cable to the fan in the printhead was too short. sorry - my fault.
concerning the printable size I tried the following parameters:
slic3r:Bed shape:size x:220 y=200
Origin x:20 y:0
RepetierHost printer settings:
x-min 0 x-max 260
y-min 0 y-max 210
width printing area 260 (x)
y: 200
z: 180
with these parameters it works and the letters are complete on the bed.
Which parameters would you use ?
And can you give me the average speed-parameters which should be used for this printer.
Thanks for any advice.

Hi,
I am glad that your problem has been resolved. If you are using repetier-host, the parameters are set as shown in the figure, and the speed is the default. You can also refer to pictures.After setting, you can click this place to center the model without setting the print position.

Hello, I did some testing and now it works as it should. today I printed a object with 195 x 195 mm.
Thank you.
