Mac connection problems with the k8200

Hi all,

I have problems to connect my printer…
Have a Mac hope someone can help me!

I build the printer up and install the driver and Repetier-Host.
I Chose in printersetings:
Port: usbserial-A…
Baud Rate: 250000
Stop Bits: 1
Parity: None
Transfer Protocol: Autodetect
Cache size: 63

All work, but the Extruder temperature is always 0.
So the k8200 dont start printing because it thinks the extruder isnt on.

I tryed to change port on virtual printer and see there the extruder temp. and heated bed are on same temp. bz 20 degres.

Did sombody had the same problem, or knows how to solve it.

I’m also using a Mac with the same settings and it works flawlessly.
Are you sure all NTC’s are connected correctly ? Also check if there is no short circuit in the wiring.

Checked it allrady. I switched the temp. pins (from extruder an heat bed).
When I chose “Virtual Printer” both diagrams go on room temperature but the motors don´t work.
So the NTC`s are working.
I have a problem in settings I think. Today I tryed it at work on a Win system, still the same problem.
First I thougt it´s the Controllerboard, get a new one, all the same…
