My feeder runs too slow and my bed starts printing 10 mm behind end stops. Ahead calibrate nice but when it starts printing it lift the head 10mm above bed.
Have to calibrated the extruder? I'm assuming that "feeder runs too slow" means it's not pushing out enough plastic. To calibrate your extruder you need to make a mark on your filament somewhere above the body of the extruder, tell it to push a certain amount through (20, 50, 100mm) and measure how far the mark moved. Then you use that ratio to adjust your steps/mm for the extruder in your marlin code, recompile, upload, retest, repeat as needed. The way I do the measuring is I stick a post it note or tape to the filament far above where it goes into the extruder then I measure that distance with my calipers. Then I tell it to push 50 mm of plastic and measure the distance again. If I ask for 50 and only get 25, then 50/25 = 2 and I change the steps/mm in marlin to be 2x whatever it was.
As for the endstop issue, I don't have a clear picture of what's happening.
The problem with the Z being 10mm above the bed ... so when it starts a print it moves up 10mm and then every layer after that only moves the right amount based on layer height? If that 10mm is only for the first layer, it sounds like you have a Z offset configured somewhere that you don't need. If your Z endstop is actually at the Z=0mm mark, your offset should also be 0.
I have check everywhere. Like i say i am bad at programming. Looks like extruder is sorted for now. But my printer go to x y and z nice but when he starts printing he lift up 10mm above the bed level and start printing. Why. I check configuration H file and see nothing wrong. Dont know where else to look.
As you can see in last video. It print nice but size different from what it must be. The printing is 9mm bigger than it should be. I am working on that.
That means your steps per mm for the x, y and z are not correct, take a digital caliper, put the head on a point, mark it. Move head like in the x axis 100 mm in pronterface. And measure exactly with digital caliper if it did do 100 or more. Say if moved 109, use the triffid hunter guide to do the math with the correct distance in the formula and put those steps into the commandline with M92 Xxx where xx is the correct new steps. I think from my head it was old esteps x distance expected / distance moved.
So say old steps per mm is 80, and has to move 100 and did 109 is will be:
80 * 100 / 109 = 79.3944 steps per mm
But always write old values down before storing permanently.
Use M501 in the command line to see all the numbers. Way below in the eeprom memory it says M92 X80,Y80,Z710.04
Now after you wrote those down, you type M92 X73.3944 and i always use 4 digits behind the comma to be more accurate.
Use M500 to store and recheck the alignment.
Repeat these for the X the Y and the Z and even the E.
Save them all, recheck and you should have the right steps per mm and no more wrong sized prints. If it still does, your hardware, the printer has been build wrong and needs extended rechecking!!!!!
That explains also why the Z axis is about 10 mm above the bed. So recheck everything, do not think ow it is ok, check it all, calibrate it as everybody has done and you must have a right printer. The firmware works perfect if i look at the video so its calibration errors.
Thanks to all the Guys that help me Especially Wvantoorn for do the software on my printer and kmcgerald for info. Thank you Grog for MRL. without mrl community my printer would not work.

Thank you
I select extrude 20mm then he
I select extrude 20mm then he only extrude 3mm
Please use the blog from
Please use the blog from richrap, slicer is nicer. And use the http://reprap.org/wiki/Triffid_Hunter's_Calibration_Guide.
After that, no more problems.
That's the one.
Yeah this is the guide I used to calibrate my printer.
Thanks for helping guys .. I
Thanks for helping guys .. I hope to be having the same problems in the near future too :D
NOOOOOO GROG DONT!!!!!!! I
NOOOOOO GROG DONT!!!!!!!
I like you alot, but please RTFM!!
Just kiddin, if your printer doesnot work, ill fix it for you
