Geeetech

Hello Folks,
after more than a year of having the printer in storage, I finally have time to look at it again.

Sadly, my extruder has sagged a lot. I already bought a new aluminum holder from the GeeeTech store on Aliexpress, but can not find the part which attaches it to the two linear bearings ...

Hello,
no, for me, neither of them worked.

Hello,
yes - the axis can be controled from both LCD and Repetier.

The Extruder can be commanded only from Repetier.

Hello,

My test sequence is:
a) Preheat ABS, wait until heat is reached

Strangely ...

Hello,
big thanks! They just confirmed intent to send a new printer controller and extruder mount!

In the mean time: could you please tell me which GPIO pins correspond to the individual stepper drivers?

Hello,
thank you so much for your response. Please permit me to note the following:
a) Cable connection to MoBo is correct, as the board would not heat up otherwise. But this is not a big problem for now.

Big problems are:
a) Motor drivers work, but the extruder still doesnt. We, IMHO, are looking ...

Hello,
I now installed the new firmware, but the extruders still don't turn. This is weird, as the motors themselves work perfectly!

Picture of wrongly crimped cable. This seems to be a common error, maybe your supplier was tired.

Fortunately, here is the repair instruction. When looking at the silver part of the cable from the top, you will see something which looks a bit like an erected hook which ...
