Title: Problem with A and B axis DRO
Post by: 1000ipm on February 05, 2011, 11:28:36 PM

I am currently developing a mach screen for my foam cutter. Have some questions about a couple of things.

1.  The axis I have setup on my controller are X-Y and A-B.  When I create the DRO's for the X-Y axis - no problem.
     The axis responds as it should - when I click on it I can enter a value - hit enter and the DRO changes.
     When I add the A and B DRO windows I get no response when I run the g-code. When I select it - type in a value hit enter-
     The value immediately changes back to 0.000.  I'm confused ????

2.  Is it possible to set up the tool path window to just display the X-Z movement without the Y.

3.  Is it possible to have the A-B axis in a tool path window - I currently don't see an option under the settings menu.

Thanks for your time -

Kris

If you don't have the A and B axis enabled in motor outputs in ports and pins, you can't change the DRO's.

Someone else will have to confirm it, but as I said on CNC Zone, I don't think you can change the toolpath display. It's always XYZ + rotary(optional), and that's it.

My first post on this subject so be gentle.  I have tried to get my A axis slaved to X to jog off of the pc. It only turns X but I can bring the MPG on the screen and I can click on the 4th axis and it moves fine. So I was wondering if I could get a screen to combine X and A so I could jog them together by clicking on one button to do both. If I use Gcode both X and A run perfectly it is just jogging them that is giving me trouble.

If your g-code is:

G1 X10

then both X and A move together, but if you jog X, the A doesn't move?

You have A slaved to X in Config > Slaving? Did you restart mach3 after slaving.

Are the motor tuning settings for A exactly the same as for X?

As soon as you slave them, they should jog together when using the X jog button.

also, the A dro will be inactive when slaved.
It won't show movement and will not accept entries.

I have A slaved to X in the config. The motor tuning has X the same as A. I only get a slight motion on A when I jog off of the PC. I can see A and X on the SS Data Monitoring when I attempt to jog off of the PC. I can use Gcode  G00 X10 and both axis move together correctly I can also use the MPG to make either the A or X move.

I noticed that the SS Data Monitoring is showing both A and X when I use the MPG but only X moves. If I curser to 4th it turns.

A bunch of email and the problem has been solved. The newest plugin solved the problem. I had to delete the old dll's that were defaulting every time I turned on Mach3. Once I did that the newest SS Plugin did the trick.
