Printed Object Scaled 200% on Z


Recommended Posts

Posted · Printed Object Scaled 200% on Z

I don't know why,

all my object show perfectly 100% scale on all axis,

but when I export on the SD card and then print on the Ultimaker Original,

all the prints get stretched on the Z axis, becoming taller by 200%.

I solved it with a work around, scaling all the objects by 50% (0.5 on Z)

but there is something wrong that I want to solve.

Is somebody there that can help me out?

Cheers

G.

Check the jumpers on the Z stepper driver area. In the red circled area, it should be like this - the first 2 jumpers installed properly and the 3rd jumper not used (it's only connected on one side meaning you could just as well throw it away and it does the same thing).

edit: 2 installed 3rd not (previously said 3 installed 4th not)

    Ok, this is what I have done:

    - I did Switch off and unplug the printer

    - I removed the fan wooden plate

    - I toke a look on my jumper settings that was: 1-2-3 --> OFF-ON-ON --> no setting correspond to this combination :-/

    - I did move the jumper settings like you suggested: 1-2-3 --> ON-ON-OFF --> 1/8 of speed if I remember well

    - I did switch back on the printer AND the printer Ulticontroller and the Extruder Blu Led are not working anymore.

    ... really don't know what happened so, I did try to go back to the old configuration, OFF-ON-ON, nothing ...

    still not working.

    - The green led on the circuit board it work fine, it's on, but the ulticontroller won't work

    - I did try to connect the printer VIA USB and the ultiController work ! ... weird, I'm confused.

    Any suggestion? :-/

    Thanks

    :-((

    with the AC Adapter

    the printer Blue LED and the Ulticontroller

    are not switching ON anymore,

    but the circuit FAN and the circuit LED are ON.

    and because via USB it's seems to work everything,

    I launched a test with USB + AC Adapter together connected.

    I runned a bed levelling wizard with Cura,

    and it work fine, even the ulticontroller it work fine,

    BUT

    in the moment I disconnect the USB cable, the ulticontroller go OFF,

    and the blue led on top of the extruder too.

    Another problem to solve ...

    somebody can help me out?

    To get a clear answer to the POST question,

    I just printed a cube of 1x1x1cm from Cura,

    and it came out with the right scale, so the jumper settings

    I assume solved the problem.

    Thanks a lot

    For some reason the Arduino isn't getting power; it should be powered from the Printer's power supply on all printers made in the last couple of years or so - but the earliest ultimakers needed to have a patch cable added to power the Arduino.

    Otherwise, the Arduino is only powered when plugged into USB - as the USB link provides a 5V power feed that is enough to run the arduino.

    All of that said - I presume your printer used to work ok without the USB plugged in? Most likely something got dislodged when you took the cover off the electronics - but I'm not exactly sure what to check. Perhaps someone else can help diagnose it.

    How old is your printer?

    I just bought the printer, it's 5 days old.

    It was working perfectly before the Jumper FIX.

    It was getting elettricity from the AC Adapter and everything was going fine.

    Something got messed up, but I don't know what ... :-/

    I discharged (like always) my body to avoid electrostatic currents.

    I didn't touch any other cable.

    I did get back on the jumper setting to see if it was the jumper.

    Is it possible to lock the power switch from the Ulticontroller?

    There are options inside the ulticontroller, now i'm not at home,

    I will check later.

    Thanks for your help by the way! ;=)

    The circuit diagram, and board layout are here:

    http://reprap.org/wiki/Ultimaker%27s_v1.5.7_PCB

    There is a zip file at the top. It contains the "brd" file which is the layout. Also the "sch" file which is the schematic.

    Both files can be opened by eagle software which is free:

    My understanding of power:

    External power supply is 19V. This goes to the stepper drivers and heater.

    19V goes through a 12V regulator. The 12V goes to the arduinio and the arduino converts this to 5V.

    The 12V might also go to one or more fans (bottom fan and print head fan)? Or maybe the fans use 19V?

    I think the 12V regulator is probably broken. If I remember correctly it is IC1 and is very easy to destroy as it gets very hot. I would check the voltages at IC1 (the part that is lifted up into the fan air flow).

    Should be 19V, 0V and 12V at the 3 pins.

    edit: correction - IC1

    In the top left corner of this photo it shows IC1 and just to the right of IC! it shows a jumper which is the jumper that brings power over to the Arduino. Check that jumper also.

    thanks for the answers.

    I will have to debug and study the situation

    Talking about the Ulticontroller menu, I do have one more menu voice NOT explained in the

    WIKI (http://wiki.ultimaker.com/UltiController#Restore_failsafe)

    named: "Switch Power OFF" inside the menu "Prepare"

    What is this option for?

    I did try to change it, but I didn't notice any change.
