Hi Jason,

This didn't help.  I've also run windows update.  The machine has been updated to SP3.

Flash Screens / Can't get Mach Nation to work

« on: April 10, 2009, 02:40:09 PM »

I'm having trouble getting the Mach Nation screen set to work.  Here's what I've done since
starting try to figure out why is doesn't work for me:

1) Installed current Mach release in a new directory.
2) Deleted old flash.dll and copied new flash.dll into plugins directory
3) Installed and reinstalled latest flash plugin
4) Verified that flash plugin is enabled in Mach config.

A screenshot of the result in Mach is attached.  The DRO's can be typed in, but the buttons don't work.

I can open "Mach Nation 11-20.swf" in firefox and it looks fine and the screen buttons work.

Any suggestions?

Thanks in advance.

General Mach Discussion / Milling arcs and circles on a cylinder

« on: July 12, 2006, 11:52:39 AM »

Hi,

I'm a new Mach3 user and need to mill arcs and circles from the surface of a cylinder.  I have a rotary table connected to my machine as the A axis.  According to the documentation, G2 and G3 work in with X&Y , X&Z or Y&Z planes.  So it doesn't appear I can program the motion directly.  I have been exploring "Formula Axis Correction" to map Y motion to A rotation and am running into enough problems (these are described in another post) that I'm thinking this is not the right way.   I'm guessing someone must have done this before, but haven't been able to find any mention of it from searching the forum.  Has anyone done this before?

Is Formula Axis Correction a new feature?  It seems kinda buggy (or perhaps I'm just trying to use it in an inappropriate way).

Thanks in advance.

David

Regarding the PI problem.  I think there is a bug or two in the expression evaluation.  I did the following tests:

PI                works (returns 3.14159...)
PI + 2           doesn't work (returns 0)
2 + PI           works
(2 + PI)        works
(2 + PI) * 2   doesn't work (returns 0)
2 * (2 + PI)   doesn't work (returns 0)

General Mach Discussion / Formula Axis Correction

« on: July 11, 2006, 02:07:45 PM »

Hi,

I am attempting to use formula axis correction to map Y positions to the A axis of my rotary table.  I made:
A = (Y * 360) / (1.125/3.14159).  If I enter y=.1 in the formula dialog and press Test, the result is 10.1859.  However, if I enter g00 y.1 in the MDI panel, the DRO shows 10.1875 at the end of movement. 

1) Why is the DRO showing the wrong value?  It appears that the bigger the value I enter for y in the MDI panel, the greater the error in the DRO at the end.

2) The rapid speed of my A axis appears to be incorrect when formula axis correction is enabled. It appears that the A axis may be picking up the rapid setting from another axis.

3) Using PI in place of 3.14159 in the above formula does not work in the formula axis correction dialog.  The result is always 0.

Suggestions?

Thanks in advance.

David
