It took me a while but I dug out the stg card and installed it. In the ini
file I had to ask for

EMCMOT = stgmod.o

First I had to locate the stg address and edit the following line for it.

STG_BASE_ADDRESS = 0X200

Then tkemc or xemc would come up but not out of estop. The error messages
reported in the startup terminal when I ran tkemc said that there was a
problem with axis emable. So back to the ini and I wound up with the
following.

; First axis
[AXIS_0]

TYPE = LINEAR
UNITS = 0.03937007874016
HOME = 0.000
MAX_VELOCITY = 1.2
P = 1000.000
I = 0.000
D = 0.000
FF0 = 0.000
FF1 = 0.000
FF2 = 0.000
BACKLASH = 0.000
BIAS = 0.000
MAX_ERROR = 0.000
DEADBAND = 0.000
CYCLE_TIME = 0.001000
INPUT_SCALE = 4000 0
OUTPUT_SCALE = 4000.000 0.000
MIN_LIMIT = -10.0
MAX_LIMIT = 10.0
MIN_OUTPUT = -10
MAX_OUTPUT = 10
FERROR = 1.000
MIN_FERROR = 0.010
HOMING_VEL = 0.1
HOME_OFFSET = 0.0
ENABLE_POLARITY = 0 *
MIN_LIMIT_SWITCH_POLARITY = 0 *
MAX_LIMIT_SWITCH_POLARITY = 0 *
HOME_SWITCH_POLARITY = 1 *
HOMING_POLARITY = 1
JOGGING_POLARITY = 1
FAULT_POLARITY = 0 *

When I had done this for each axis, it came right up. I don't have
encoders hooked up but will try that soon.

Good luck with your project.
