Therein lies the rub, Ron. The stock generic.run requires a bit faster pc
inorder to live comfortably with your 200 MHz processor. If your
generic.ini looks like this. (move the file browser to /usr/local/emc and
click on generic.ini to bring up an editor)

; Name of motion control program
; EMCMOT = steppermod.o
EMCMOT = freqmod.o

Change a couple of values in /usr/local/emc/generic.ini as follows.

; Base task period, in seconds
; PERIOD = 0.000016
to something like

PERIOD = 0.0005

and a bit further down

MAX_VELOCITY = 0.200
DEFAULT_ACCELERATION = 2.0
MAX_ACCELERATION = 2.0

You may also need to look at

INPUT_SCALE = -4000 0
OUTPUT_SCALE = -4000 0.000

Now if the motion controller looks like this.

; Name of motion control program
EMCMOT = steppermod.o
; EMCMOT = freqmod.o

Then you will have to comment out PERIOD (put a ; in front of it) and
reduce either/or input scale and max velocity until you get a combination
that will let your PC live.

Hope this helps. If you'd like me to talk you through it, sit down at the
pc and call me. (email for my phone number)
