Hi All
I am trying to print an item that is 200 mm long. When I try to print with this dimension on the x-axis, it is being cut off at 180 mm.
I have looked at the printer shape in the printer settings, it says X Min 0, X Max 200 and bed left -38.7. I am loath to make any changes that might cause any damage.
Could anyone please tell me if these settings are correct and how to find my missing 20 mm of print area.
Using move axis, the print head travels 0 - 200 ok.
Many thanks for any help.

On the Y axis you only have 180mm but on the X axis you should get 200mm. But if your object is 200 mm long you can’t print a skirt as if would fall outside the boundaries.
Thanks Raby
The thing is that it cuts the skirt off at 180 at well.
I am beginning to wonder if I am positioning it in the right place on Repetier.
My early results indicate that on-screen in Repetier, your actual print area starts 40mm (4 grid squares) from left, 20mm from front and right, and 15mm from back. In theory, to print 200mm you will need to eliminate any type of skirt, brim, raft, etc. which you can do in the config. In reality, however, I noticed that my X direction only printed 198mm or so, so if this is common to all K8400s, this may also impact your goal.
Hello
i had the same problem, i wanted to print a main board cover/cooling duct but it was to large.
after searching i changed some settings in the firmware and now i can print 215 mm long.
You can make it even longer, but watch out for your pulleys and printhead, test it first in repetier manual mode.

how about rotating it 45 degrees over the z-axis in repetier while placing? diagonally it should have a theoretic length of about 180 * 1.4 (square root of 2) = 255. of course idk the rest of the shape:)
Hi,
is it possible to post the pics again or make a reupload?
Or can someone wirte it what to do to get a bigger Print Size?
Thanks a lot!
PUSH!
Really no one here who can help??
I remember some months ago there was a post with pictures how to hack your setting for larger buildsize, but I can’t find it anymore. It’s somewhere, I think, in the category Improvements…
To achieve this, you’ll have to make some modifications at your own risk :
Change the parameters in the configuration.h file of the Marlin firmware :
// Travel limits after homing
#define X_MAX_POS 200
#define X_MIN_POS 0
#define Y_MAX_POS 200
#define Y_MIN_POS 20 change for 0
#define Z_MAX_POS 190
#define Z_MIN_POS 0
To let the Y axis travel to 0 you’ll have to set the small fan horizontal to let it pass above the X clamp (but this will lower the flow on the printed piece and the PEEK tube).
In Repetier/ Printer Settings, go to the tab : printer shape and change :
X max to 215, bed left to -25 (Warning : this wont work for the 2nd extruder) and Bed front to -1.
With these modification the print size of Extruder 1 will be 200x215 instead of 180x200.
Thanks!
Will try it soon!
Sorry the configuration I gave you is not complete :
Here is the right one to get the full surface:
In configuration.h :
// Travel limits after homing
#define X_MAX_POS 215
#define X_MIN_POS 0
#define Y_MAX_POS 200
#define Y_MIN_POS 0
#define Z_MAX_POS 190
#define Z_MIN_POS 0
//Manual homing switch locations:
// For deltabots this means top and center of the Cartesian print volume.
#define MANUAL_X_HOME_POS 215
#define MANUAL_Y_HOME_POS 200
#define MANUAL_Z_HOME_POS 0
Repetier/ Printer Settings / printer shape :
Xmin 0 - Xmax 215 - Bed left -25
Ymin 0 - Ymax 200 - Bed front -5
Print area width : 240
Print area depth : 200
Thank you very much for help!
Everything is working fine!
Very valuable information, thanks
