Hello , Newb here. Just bought 2 , very nice Bridgeport and Jet mill retrofits , with Microkentics Steppers and PICO Universal Stepper cards , from the estate of a friend. Machines are very nicely built.
They sat idle since 2013, the Cmos batteries were dead . Ive been working on the .ini file of the Jet mill , to correct the homing sequence.
Everything was great , fixed the Z Axis homing . Powered down the control to plug the A axis in . Now on power up , it will not load Linuxcnc 2.4.5.
Is there a way to decode the error message , to see what i need to change, to return functionality ?
   The computers are bare bones machines, no network capabilities , just USB.  
             Where can I look , or were do I Start ? 

Thank you. I tried both V1.04 and V1.11.

But I couldn't make servo drive move in LinuxCNC main screen.
I didn't see any error on screen,  but servo drivers didn't become "Servo On" state when I pushed "PowerOn"

Where do I need to check ? ( I used to use another tiny LinuxCNC system and machine , but it was stepper.., I used step conf. )
Do I have to set some servo parameter from switches on servo driver ?
( No load is connected to servo motors for now. )

Servo Driver Panel shows "20ry" (2 is blinking.)


I tried both V1.11 and V1.04 and this configuration,

I have 3 sets of Lichuan Servo (Driver+Motor), I want to use them as XYZ CNC.
