Geeetech

Hi Gingko,

Yes, it seems A.
Hmm...
Thanks a lot anyway. I am keeping in touch with a guy (Lei) in Geeetech.
He also suggested me to check with multimeter.
I don't know what to do now, except replacing extruder....

I heard that every 3D printer owners have frustration in the early stage like lots ...

For not heating problem, do you have a multimeter?
Try to test the voltage of the heating rod, when heating it should be 24V.
You can also check if the wiring of extruder/heating rod loose or damaged or any kind of poor connects, for example, the female interface of heating rod.

Z goes up:

Hi MachielK,

I just tested the firmware you provided at 'Thingiverse' and it works fine I guess.
Although all the menu was in German, I could translate with Google Translate.
It says....

heizen fehlgeschlage
drucker stopp
bitte resetten

which means....

heat failed
printer stop
please reset

Wow ...

Hi MichaelK,

Thanks for the info. But, well... I am pretty sure that I used the right firmware.
Because, when my printer boots up, it says 'A10' and I downloaded A10 firmware, filename was 'A10' from this website.
Anyway...

I just visited the website and it is already versioned up to 1.1.9.
I will ...

Firmware:
Yes, I followed the instruction using Arduino 101 and A10 firmware from this website.

Auto home:
Yes, it was acting like that before updating firmware.


I don't know what other problem this machine has. Honestly I am not trying to do anything else.

Hi,

I found another problem after firmware update.

When I set 'Go Home', printer head goes up all the way up and does not stop until I cut off the power.
Please have a look at the video I recorded.

hmmmm. please help.

Thanks for detail explanation with a photo.

With you guide, I experimented several things. But it still doesn't work.
Wiring and software seem OK.
Anyway, please have a look at the photos with my description.


Before doing anything. LED is not splashing.

But I think it may not be the problem of firmware.

You can loosen the screws of mainboard box, check if there is a light flashing near the extruder wiring slot when heating nozzle.

Or, you can check if the wiring of the hotend heater loose or not.


Yes, I totally agree that it doesn't seem to ...

Yes, I just did it with big doubt.
The reasons I am saying 'big doubt' are
- It worked when I got it: if it were firmware problem, it shouldn't work from the begining.
- Using old version of Arduino??? : yes I could upgrade the firmware amazingly with old version.
- I got A10 just 5 days ago, too ...
