        <title>Home positioning and jerk details</title>
        <description> Hi gize, how you all doing? Im trying to build my first 3d printer and as i am on my final steps, im having a few issues that im not findind the answer.

1- home position: Every time i start a print or just click on home position on pronterface, (The Z goes fine, down until it hit the endstop and then stop) the X and Y goes until the end of the heat bed instead of stoping in the middle. I thought of just hand positioning on the print, but then i realized each layer of the print goes back to the home position, so that wont work. I tried looking for a topic, but i could not find any one that would help me, so if any one know what to do, i would appreciate it! Also, im a newbie, so try to write as much information as possible, even if it sounds so basic for you (i will leave my configuration file here). 

2- What should i put on X, Y, Z and E Jerk settings? I am using a less potent motor the Stepper motor 28BYJ-48.

Thanks for the help guys!

Ohh and of course, if you gize see by chance any mistake on my configuration, please just leave it a note! Thanks :)</description>

            <description><![CDATA[ "the X and Y goes until the end of the heat bed instead of stopping in the middle"<br />
why  would you expect it to stop in the middle?<br />
<br />
0,0 is front left of the machine (presuming I3 type machine), and this is what its trying to locate<br />
<br />
If "middle" is an exaggeration and you means its out a few mm from the 0,0 position <br />
<br />
if so change your positions<br />
<br />
ie <br />
#define X_MIN_POS 0<br />
#define Y_MIN_POS 0<br />
#define Z_MIN_POS 0<br />
#define X_MAX_POS 120<br />
#define Y_MAX_POS 120<br />
#define Z_MAX_POS 100<br />
<br />
eg if X is left is -5mm left of 0, then set X_MIN_POS -5<br />
<br />
"but then i realized each layer of the print goes back to the home position" <br />
this is also not normal behavior..  normally printers only home at the start of each print job. (but it could be made to do that, would normally be a slicer setting)]]></description>
