Geeetech

ok, here is a photo.
Now I will contact Geeetech for a replacement PSU. So I hope for goodwill, because the printer is only half a year old!

Well, well...
One resistor (R23) has no leg

I cared more about the outer photo. Especially in a place with a label. To see what it is.

that's right, R23 only has one leg left. Also R28 is broken. For the white material on the electrolytic capacitors, I first thought that one of the capacitors had burst, but it is probably an elastic adhesive. But during the desoldering, I noticed that there is a cold solder joint on a connecting leg (both capacitors are ok.).
Here is a picture of the type of PSU.

Hi.


Thank you.
Now we all know what to avoid.
This is a budget version, which is worth avoiding with a wide arc

Yeah, it's white. It's glue. Its purpose is to absorb mechanical stress, and it will keep large elements in place. In this way, the leads will not be torn out of the component and PCB.

Hi,
Your printer is the old version and it uses the 12V version PSU.
The new version PSU is the 24V type.
We suggest you upgrade it to 24V PSU as soon.
You can find it at:
viewtopic.php?f=92&t=61498

I would like to do the upgrade to 24V, but I can not find the required spare parts (except the PSU), neither under the name nor under the specified order number. Is there a complete upgrade kit?

You can contact the sales at first.
Then ask them the 24V upgrade kit for A30.
They will give you more help.

and it was: the heating bed!

after I installed a new PSU the message came again and again after a short time:
Error Nozzle-0-Temp, the printing job has stopped.
When I replaced the temperature sensor and the heating cartridge one after the other - no change.
Luckily, yesterday came a new heatingbed from Geeetech - switched to 12V, installed - and everything works well again!

Hi.


It was a nasty malfunction. But you did well, and that's why I'm happy about it.
