Geeetech

Hi I am an (older LOLS) Aussie girl and VERY new to 3D printing, but have recently successfully put together a Geeetech Prusa i3 kit. However I have really had to research every step of the way and finally, after about a month, I have been getting some fairly good prints. HOWEVER, the best print I am getting is from one of the first STL files I dumped into Repetier, sliced with slic3r (the integrated one) and then saved to SD card. Problem is I have altered my slic3r settings several times since I originally saved that file and don't remember what they were at that time. Now I want to replicate those same settings for other files not printing so well, which probably, (but not definitely) slic3d with different settings. My config h file has remained consistent while doing doing these tests.

My question is - is there any way I can find these settings from the saved file on the SD card (the gcode file)? I see the temps, but the nozzle width (have several), layer height, speeds, etc? I am guessing they have to be *somewhere* in there as how else does the machine know what to do???

Thanks!
Jan

Hi,Jan
You're so smart.
Yes,the Gcodes in every line stand for different "command".
You can modify the Gcode to modify the corresponding printing settings.
And i guess you may wanna read this article about "Gcodes":

Thanks William, yes I am aware G-code is a series of commands to the printer. However my problem is that I don't see anything anywhere relating to the information I seek regarding nozzle width, layer height, speeds, etc. The G codes that are there are seem about temperature, fans, retraction and movements of axis. I cannot paste it as it exceeds the allowed message characters, but I uploaded here if you care to look. https://dl.dropboxusercontent.com/u/42779103/gcode.txt I would be grateful if you can tell me where to look.

Thanks
Jan

No worries,Jan
As far as i know,I quote two line of your codes to describe it:

G1 Z0.3 F7800
...
G1 Z0.56 F7800

"Z0.3" means the first layer height is 0.3mm,while "Z0.56" in the next line means your layer height is 0.56-0.3=0.26mm,and "F7800" means your travel speed(non-printing speed) is 7800mm/min,which means 130mm/s.

G1 X76.753 Y80.357 E0.15217 F1800

In these codes,the "F1800" codes mean your printing speed is 1800mm/min(30mm/s).
As for the nozzle width,i have no idea about it in the G-codes...

Ah, excellent, exactly what I needed and information hard to come by. Thank you SO much!
