HK Turnigy Fabrikator - Upper layers not solid

[PhilippG]

I think you have your hot bed and fan connected backwards. D9 is connected to the fans. D8 to the hotbed.

I have connected them the way you described it.

I even disconnected the cables and connected them to another 12V supply to see, if the labels were correct and if there might be a shortcut anywhere.

The mechanical connection is right.

I even flashed the firmware you uploaded to the printer, but still the same issue.

UPDATE:
I completely disassembled the Control board to get to the Arduino Mega.

Digital Pins 8 and 9 seem to be shorted.
I tried with a custom sketch:
Both Pins Low: 0V
Both High: 5V
One Low, the other High: 2.5V

The measured resistance between D8 and D9 with the Arduino off is < 1Ohm.

I thing my Board is broken.... replacement is on it`s way...

PROBLEM SOLVED!!!

I pried of the pinheader for D8 and D9 on the Arduino and discovered, that the metal-contact of D8 inside the pinheader had one half of the contact in D8 and one in D9, so it bridged the two pins.

A faulty pinheader caused all of this.
I desoldered the header and added a new one. Now my printer runs like a beast :-)

I have flashed the firmware joop posted. I seems to work better than the original one!

Thank you to everyone, who tried to help

Hi just got mine together today. I lit up and I went to move the extruder and the screen went all white.
What did I do and how to fix?
Can't find the troubleshooting section in HK "Files"
