Extruder runs into Part after Printing...
-
I can't answer with confidence for simplify3d but Slic3r has configurable gcode that it adds to the end of print that includes moving the head out of the way and disabling heaters. I'd be looking for something like that in your slicer.
-
Thanks. But I already checked that. Added: in Slicer:
M104 S0 T0 ; turn off right extruder
M140 S0 T1 ; turn off bed
G1 S2 Z5 F100 ;
G1 S1 X-205 F1200;
G1 S1 Y-265 F1200;
M84 ; disable motorsSo doesnt seems to be the Problem. Could it be some routine at the DUET Board?
-
As @DocTrucker has said. If you take look at the end of the gcode file you've printed, you'll find a command something like G1 Znnn. It's quite normal for slicers to be configured to raise the print head (or lower the print bed) at the end of a print and it sounds like yours is going the wrong way.
Edit. Was typing the same time as you. -

Unlikely. Can you post the last few lines of the gcode file you were printing.

I just checked. Nope seems to be correct:

; layer end
M104 S0 T0 ; turn off right extruder
M140 S0 T1 ; turn off bed
G1 S2 Z5 F100 ;
G1 S1 X-205 F1200;
G1 S1 Y-265 F1200;
at the end of the File.
And positive Z in Down not up on my movable Printbed. Works with all other Perimeters too. So no Idea what he is doing, from my side...Also he doesnt Home X and Y as commanded, he just raises Z instantly after the last Print step.

@glockster Ok. The reason is that the gcode commands in the file are all absolute (as is normal) That is to say, the positions are all with respect to home which will normally be zero for all axes.
So the command G1 S2 Z5 F100 will try to move the print head to the position 5 mm above the bed and as the prior position was 87.75 mm, it is going to get nasty. So what you need to do is add the command G91 prior to the G1 Z command. This will change the coordinate system from absolute to relative, meaning that the subsequent G1Z 5 command will move the print head by 5mm from where it happens to be, rather than to 5mm above the bed.
HTH
EDIT. If you want to move X to -205 and Y to -265 as well, you need to either do that before you add the G91 command then do G1 Z5. OR do this:
G91 ;set relative
G1 Z5 F100 ; lift head or lower bed by 5mm
G90 ; back to absolute
G1 X-205 Y-265 F1200 ; move head to X-205 and Y-265 -
Great, Thank You!
Will try and leave a feedback. -
It worked fine. Thank you guys for the help!

@glockster Glad that fixed it. Can you edit the title to mark this thread as "Solved".
