Geeetech

Hi,

I've buyed my first 3D printer and it's a Geetech !
The build was easy and everythings is well explained with the instruction manual and the videos.
But, i got an issue with the electronic parts.

I've wired everything correctly (checked twice, wired once) but after turning on, the power supply make a weird noise and the small LED on it stopped shine.

So for troubleshooting i've check the topic on your forum.
- fuse OK
- launching the power supply disconnected from the load(GT2560) : 12 v
- Connected on the GT2560 : 0v

After that i've tryed to use my lab power supply and, same problem, the GT2650 does not start ( no LCD, no Light ).
- The power supply give 20A at 12v
- Power supply disconnected from the load (GT2560) :12 v
- Connected to the GT2560 : 12V

For testing my GT2560 board :
- Remove all the wires
- Remove stepper drivers
- Connect on the PC : Not detected by Arduino IDE
- Checked in dmesg (im on linux) NOTHING

My guess :

Power supply does not support the load - > Dead ?
Even with external power supply, the mainboard is not working -> Dead too ?

My question : What can i test ?

I've ordered this printer from GEEEtech shop on ebay, can i get replacement parts ?

You should contact sales to sending you a new mainboard

You think that the only problem here is the mainboard ?
Should i contact the sales by Ebay or using this website ?

Should i contact the support via ebay or via this website ?

Contact the support via email, it might take them some time to respond, guess they are pretty busy.
I just had a faulty board and ordered a new one. My old one would not power up when plugged into my Usb port.
The new one just goes on straight away.
Hope this was somehow helpfull for you

Either directly through the website or your reseller if you used one.

Had a similair problem, after providing some tests they will make you do with a volt meter, they shipped me a new board.
Now printing very happily. Currently upgrading the Hot Bed to a MK3 Black Alu, and 24v.

Hope this helps.
