Loading Marlin on a new controller

[ibyt8bits]

One driver on my cheap Chinese knockoff of a Prusa I3 died.  I bought a replacement controller with replaceable drivers:

KINGPRINT KFB2.0 Controller Board for Reprap Mendel Prusa I3 Kossel 3D Printer.  I followed the youtube.com video Marlin v1.1.8 3D Printer Firmware Complete Config - 2018 - Chris's Basement and edited the Configuration.h and Configuration_adv.h files.  Compiled it using Arduino IDE but had to export the binary and load it manually using the following command: /usr/bin/avrdude -p m2560 -P /dev/ttyUSB0 -c wiring -b 15200 Marlin.ino.with_bootloader.mega.hex.  I connect using Prontorface and get the following output:

I checked the both thermistor's resistance.  Both read 124 ohms.  Rechecked all the plugs.  

What's killing my printer?

Just a guess that it's expecting an E-stop button attached and you do not have one attached? If that's the issue, you could either change that firmware setting, or jumper-wire the e-stop pins together.

Ryan,

Thanks for the reply.  I went to pins_KFB_2.h  file and changed all KILL_PIN values to -1.  The pins.h already defines the value as -1.  I've looked all over the board for a physical pin. Did not find one.  Recompiled Marlin and loaded it, but still get the same read out.   I am using the REPRAP_DISCOUNT_SMART_CONTROLLER.  Is there a kill button setting in that?

Any other ideas?

Ken

No idea, sorry. Try doing a clean Marlin install from an online configurator to see if the error is tied to your firmware compile or to hardware?
