Art,

I have everything working on my 3D printer except no movement on Y axes.
X pins 7 and 1
Y pins 3 and 8 ( I tried switching them but same thing)
Z pins 4 and 5
A pins 17 and 16.

Moch 3 same computer works fine.

Any help?

Thanks
Jerry

Great, I have time this afternoon, will configure again everything and try the MPG and let you know.

Pablo:

 As of last nights version, yes, it is turned on. Set the MPG count and encoder number and it will send a message each time the increment is
equal or more than detent.

  If you switch the X and Y settings, does the Y then move when you try to move X? Does X move when you try to move Y?

X Moves when I try to move Y
nothing moves when I try to move X

I switched the pin assignment only.

Well, that proves its not Mach then. :)

 OK, so we need to know why pin 3 doesnt work ( Im assuming the STEP pin is pin 3? )
Well ignore the DIR pin as if it was bad the motor would still move, just in the wrong direction.
So search for any signal you may have turned in in other motors, or outputs that is set to pin3.
Its about the only thing that can stop you. The pin will not be set to step unless no other pin uses it.
  Pin3 is a bit in the 8 bit area of pins 2-9 , so theres nothing particularly special about it, so I cant see
anything other than 2 possibilites, the Y axis isnt working or the pin 3 signal is getting overwritten by an output
or other motor..

Any chance its that?

Pin 8 is step but I tried switching 3 and 8 no go.

All outputs are disabled.
All inputs are disabled.

I will keep playing with it.

Thanks Art

The Index number is real HI,  like 25018  when jogging motor #1
Motor #0 is 3221

Art,

What would cause the a motor to move in darwin? It makes no difference whether the motor is enabled or not. I have had trouble with this since 1.145 although I never tested versions 1.15 or 1.16. Version 1.18 does this as well.

The index doesnt matter, its just a count of how many steps it has moved since turn on..
