in mach go to config, general config
make sure a axis is checked as angular if your working a  as a rotary axis
if its not broken yet, fit more gadgets!

also in mdi screen if you issue g1 a10 f100  you are only asking for 10 degrees of movement. if axis is at that position it wont move (check on a axis dro for movement in numbers)

type G90 first to set mode to absolute movement
try G0 A350 F1000
then G1 A100
should move 250 degrees if you have steps per right

OK, I want to list to you what I have done.

1. I set the Galil plugin according to the .pdf.

2. I enable all my home and limit switch's (they trigger nice when I push them)

3. I enable the A-axis in config>ports and pins>motor outputs. (only the A-axis since that is the one I'm testing)

4. I calculate my counts/deg, which is 1000.25 counts/deg. And I put this number into "Motor Tuning".( to test this count, with the reset button off, I move the A-axis servo motor by hand and the DRO's are correct for the deg I move the motor.( I picked 10deg to test it with)

5. I then calculate the velocity. I want the A-axis to move 5deg per sec., so I times 5*60 and I get 300. I put 300 in the velocity box in "Motor Tuning" and I set the accel to 30deg/sec (10% of velocity).

6. I then save the settings then restart Mach3. I go back to "Motor Tuning" and use the arrow keys to move the motor. It is VERY slow at these settings, I have to put my hand on the pullys to feel the motor moving.

Does this seem to be correct? I tried MDI and the A-axis still wont move, when I hit enter I get the "Default Beep" out of the speakers from Windows.

Hope this INFO helps.


Thanks,

Aero

I checked that and it was set. In config>general config I have "Angular Properties" and "A-Axis is Angular" is checked. "Rotational" ,in the same window, is set to "Rotational Soft Limits".


Thanks,

turn rotational soft limits off. as you havnt set them up
(these get set up in config/ homing)

OK, I made an .avi of the motion on my A-axis, along with a SS of my "Motor Tuning" Screen.



Click here for the video: http://www.chill-a-hz.com/images/cnc/a-axis.avi. Notice the jerk, I was holding down the up arrow key the whole time.




Here is the SS of my "Motor Tuning". No matter where I set the velocity or accel I get this motion. I can turn it way down and you can see it, but I still get no motion in MDI.


Thanks,

Aero


EDIT: the velocity and accel are not set to my earlier post, but I turned them up so you could see the jerking.

I can make the motor move with the jog/MPG window, but it only moves .011 when I click the 4+ arrow, even if I change the "cycle jog step". It wont move every time I click it, I have to wait a few seconds between clicks to make it move, and even then it is touch and go.



Thanks,

Aero

Look at the calculated G force!  Almost 13 Gs!  Your acceleration is still too high.  We humans black out a 4 to 6 Gs.  :)  And I think you are blowing the controller's mind.  Set your accel to get a G force of less than 1.

have you set the setup units in mach to your preferred measurement? mm or inches?
config, setup units. set once and forget.
it may be that your getting 25.4 times less movement than you think you want?

ive pulled 4g in my plane- noooooooo dont want to do that again!
but -3 g feels much worse.

Heh...  I bet -3 does feel worse!!!  :)

The units could be one issue.  But getting that acceleration correct is going to make things a lot better.
