        <title>strange Z height.</title>
        <description>Fairly new to all this and having fun de-bugging my printer.

right out of the gate I got a couple of really nice prints. I currently have a strange problem with my z height.
I have my bed well trammed in all around. I&#039;m using slic3r with a .3mm layer height. The first &quot;wipe&quot; move is great- nozzle lays down a nice bead and then moves in for the print and nothing sticks to the bed. I tried adjusting layer heights, raising bed temp, hairspray on the glass etc. I finally realised that the z was jumping up after the wipe move. I paused the print on my last attempt and sent M114 command. i got a return of .95 for Z height. I put a -.9 offset in sclic3r and the print came out fine.
Any ideas on where this wierd offset would be coming from?
Thanks,
Peter</description>

<br />
Repetier automatically installs Cura and Slic3r so there isn't a different version to download.  You can choose it from the software after you get it installed and launched.<br />
<br />
See here:<br />
[<a href="http://www.repetier.com/documentation/repetier-host/slicing/" target="_blank"  rel="nofollow">www.repetier.com</a>]<br />
On the main screen there is a tab for Slicing.  On there you can choose Cura, Slic3r, etc.]]></description>

            <description><![CDATA[ I manually set in the gcode my z axis to start at 000.60 and it was damn close to the bed but still off.  im thinking home is about 000.30 or 000.40.  If I can just get the printer to figure out its home setting for the z axis I think it will solve this issue. ill continue playing with it.]]></description>

            <description><![CDATA[ just FYI when I hit z home.  it trys to keep going past the home area.  it hits the limiter and tries to keep on going and the motor buzzes as it gets stucks trying to keep going.<br />
<br />
UPDATE so I got it zero'd with that program.  It was at a good height while centered.  Even though the home keeps trying to go lower.  <br />
<br />
HOWEVER<br />
<br />
now the printer wont print it moved the extruder all the way left to the stop that stopped fine then the z axis tried to lower itself.  So I take it that may be a setting in the code of the file again.   but im not sure that is just what happened on first run.  I'll await your return sir.  Until then ill continue to try playing around.]]></description>

            <description><![CDATA[ those look good actually see where you have homing offsets you could try adjusting the Z one see if you can get it down to the bed that way but before you do if you go to the manual control tab you should see the controls and hit the z home icon and see where it ends up if it is close to the bed then good I'll be back in at around 5 uk time.<br />
<br />
Did you install Rep host with Cura if so we can configure that and should be good to go if it homes ok]]></description>

            <description><![CDATA[ we may want to reset the board to factory defaults before we start so I make sure it detects that z axis limiter on its own.  and is it best to start the screws at the top before testing that then let them come all the way down to the switch?  it did not specify when they had me turn it on and do that earlier.]]></description>

            <description><![CDATA[ its under config at the top<br />
and then its fairly obvious just hope that board has an eeprom on it (I Think it does) if you can try and get a screen grab of page and we'll see where we go I need to go out now and will be out for a few hours so not sure if you'll still be around when I get back?<br />
<br />
If you can get thos grabs I will attempt to do a Repetier config for you and send you the Configuration.h which you will be able to put into the config tool and then download all the rest of it from there.<br />

            <description><![CDATA[ sorry it was already set to that by default.  For some reason it just keep starting the print at 0.29 on the z axis instead of coming down close to the limiter switch which is where the bed is.  The 0.29 is about 1/4 or maybe closer to a 1/2 an inch higher than the bed looking at it currently.]]></description>

<br />
try changing the G28 lines to be G28 ; this should then move all axis to the Min endstops (Just wonder if having 2 separate lines in there are affecting it in some way) The other thing you could do is to clear out cura completely and re-install the latest version of it which is 14.12.1<br />

ah how do I do that?  I am totally new to this as per my post.  I am using Cura 14.07 and just using the files they provided me on the disc to do a test run of the printer.</div></blockquote>
<br />
You can open one of those gcode files in a text editor or notepad and cut and paste the first few lines if it is an STL file then your cura is inserting the lines and may be set wrong <br />
<br />
also check the screen shot of my CURA attached and make sure the start codes are correct. Doesn't look like Cura has a manual cmd function (I Don't use it so not that familiar with it)]]></description>
