Mach3 and G-Rex / Problem with Grex and MPG (analog in/out also)
« on: June 22, 2007, 12:47:24 AM »
Hello, It's been a while since I messed with my Grex and so far I am not having too much luck.

I downloaded the latest Mach and the firmware files etc and flashed the Grex.  All is up and running.

I think, though, that something isn't quite right.  I am trying to get the MPG to work and the analog in/out working.  I have it all hooked up and settings correct, but when I flash the Grex I get the following message....

I followed a post from Chaoticone to configure the MPG. 
When using the Grex monitor I still have never seen anything from the encoders.  I also tried to set up the analog stuff with the same results.  I am beginning to think that I am not actually flashing my Grex and that is why it isn't doing what I tell it to.

I also have connection issues with Grex.  EVERY TIME, I must...

1.   Start Mach3
2.   Plug in the Grex
3.   Type in the IP for the Grex
4.   set temp address
5.   restart discovery
6.   repeat 4 and 5 again

and then it will continue working continuously.  If I shut down Mach3 but not power down the Grex, then when I run Mach 3 again it will connect fine.  Something is going on during the boot up of the Grex (set to 3 seconds boot delay).  If I power up the Grex before I start Mach 3, It will crash Mach3 every time.  I have installed two versions of Mach in the last few days and I don't suspect a corrupt install.  I get the following message ALL THE TIME!!

Bottom line is that I have everything running fine (digital in/outs, motor step and direction on all 6 axis).  I just can't get the analog and encoder/MPG stuff to work.  I have messed with this for 3-4 hours now and I think something is not quite right.

Please offer up any advice.  I would like to get this working before I pay for the Grex license.
