Thanks for your help, I am now able to talk to the board and have it recognized by repetier host.

I am not using this board at a 3d printer, only cnc mill, so I have no thermostat hooked up, therefore I have installed a 100K ohm resistor to the “T0” on the board per the assembly instructions. I am trying to make sure motors are working and pots set correctly, but am unable to have any manual control over the board. I keep getting a new error message telling me “extruder switched off. MAXTEMP triggered!” and then after that an Error code of: “Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)”

I have googled the above and tried a myriad of different tweaks, but to no avail. If I’m missing something easy (more than likely the problem), if someone could point out my bonehead mistake, I’ll keep pressing on.

Thanks again for everyone’s help with my issue.
