if you have a quick look to the dyn4 Manual it says clearly that all Input signals are isolated.
also the example wiring diagram of the analog Input Shows nothing to connect AIN- to somewhere else
as the analog out ground of the source.

so why are you trying to create Problems ?

i would prefer to run AIN- and AIN+ directly via 2 wire shielded / twisted cable to the Motion Controller and
put shield on Motion Controller side to GND. the analog Input of your dmn dyn4 is isolated so do not connect
AIN- to Signal ground bus.

i had a look to your Profile XML. Looks fine so far.
only in motortuning is a 0 for Step Pulse (all axis).
IMHO there should be something from 2 to 5.

Looks like your machine has a BOB witch Needs Charge Pump enabled,
so the Step Pulse might not be necessary, but you can give it a try.

next step would be to check pulse signals and Charge pump Signal via oscilloscope
i think and also check the signals to be 5V not 3.3V, because older parallel ports used
to be 5v and newer ones 3.3v.

That is the only idea i have for the Moment.

normaly you put  all chasis grounds to your earth potential.

for a anlaog Signal you use a two wire (twisted) shielded cable from the
source to the Destination and shield should be wired to the GND of the source
(of cource i hear all the voices witch say do no do this), but for a good start
it was the best soluition for me for the last 35 jears.

the G-code is ok, just wanted to see that there is a F value at the first G01 move.

just ideas (i realy do not know what the problem is):
-parallel port 5V - 3.3V Problem
-mach3 Version Problem

if you say machine just sits there dro are moving, is the g-code window also going throug all the lines?
have you tryed to do machine moves by entering in MDI Input?

can you post your  g-code file?

I have played a Little bit arround, you can a custom Screen witch has the double width of your single Monitor and enlarge the Mach3 window over your two Monitors.
thean you can have (by copy paste) both on the new Screen.

if you go to diagnostic page you can see Machine Coords.
if one of These is out of the range you have defined in Config -> homing/Limits
you are not allowed to turn softlimits on, that is what the errormessage means.

you can  use your Y- and Y- Switch as reference (home) Switches.
just use the same port/pin Setting for home Switches.


have a look a chapter 4.5

after you have homed your machine you can use softlimits and slow Zone.

to bring your 0/0 (home) for a part into the Center off your table you can use G54 and following
work Offsets.
