General Mach Discussion / Wrong move when executing macro.
« on: December 29, 2009, 03:04:30 AM »
Maybe the subject does not describe my problem correctly.
The problem is the following.
I have a program which includes a macro.
Is named M1001 and placed after the first G00, is to wait a few seconds and after that energize an output.
The macro is executed correctly.

This is the M1001:
code ("G0 Z0.00")
While ismoving()
wend
ActivateSignal(Output1)
SetUserLed (1001,1)
wait = GetUserDRO(1041)
code ("G4P" & wait)
While ismoving()
wend
SetUserLed (1001,0)
code ("G4 P0.2")
While ismoving()
wend


Now if under ActivateSignal(output1)
i place ActivateSignal(output2)
to have 2 separate outputs,although the screen shows the right path,
the machine does not follow the path.
Usually, if lets say we have rectangular, the shape is left open about 20mm before ending.
Or other times only one dimension (usually at Y axis) is not correct (10-30mm shorter).

Then, by removing the second activation from the macro,
it comes back to the proper path.

Have you seen this problem again?
Any ideas-comments would be helpful...

General Mach Discussion / Image LED on Mach3Screen.
« on: December 08, 2009, 08:15:24 AM »
When using "screen4", we can use bitmap LEDs by showing the bitmap path to the properties of the LED.
Where is that setting in Mach3Screen? I can't locate it...
Thanks,

General Mach Discussion / Designing problem on Screen4.
« on: October 12, 2009, 04:16:19 AM »
Have you ever seen the following problem on Screen4?
Sometimes when saving the .set file and open it with mach3,
the whole screen has moved down usually about 100 pixels.
Sometimes more than the size of the screen!
Is that due to any mishandling of mine?
Or is that a bug?
Have you seen it?

Also, when designing a wizard, the bitmaps are not shown on screen4.
I have to move all files to mach3 folder to design it and then back to addons folder to see it with mach.
Any comments on this?

regards,
giannis

General Mach Discussion / Wizard for editing a ready tap file.
« on: August 24, 2009, 06:19:58 AM »
Is possible to make  a wizard that can edit a ready shape?
My will is to recalculate a ready shape and change the dimensions of this shape.
For example
if there is a line G01 X20 Y0,  i want to add 5 more units to X axis and 3 to Y axis (these values will be on user DROs), so it will be G01 X25 Y3
Can that be done?

General Mach Discussion / "Plasma torch" and "marking torch" offsets.
« on: July 25, 2009, 08:09:11 AM »
Do you have any ideas on how the following will be done?
Suppose that we have "plasma cutting" and "plasma marking" torches, both to a machine.
First the marking should be done and after the cutting.

The G code has "macro" commands before and after marking.
The Zero point is given at the cutting torch.
So, before marking, there should be an offset movement (this will be the distance between cutting and marking at both axis).
And after marking, also there should be a movement back to the original values.

Has anybody faced that?
Any ideas would be helpfull.

I allready have tried the following:
This is before marking:
a=GetOEMDRO(83)
b=GetOEMDRO(84)

c=GetUserDRO(2012) 'axonas X offset plasma
d=GetUserDRO(2013) 'axonas y offset plasma

e=a+c
f=b+d

SetDro(0,e)
SetDro(1,f)

code "G0 X" &a
code "G0 Y" &b
While ismoving()
Wend


And this is after marking:
a=GetOEMDRO(83)
b=GetOEMDRO(84)

c=GetUserDRO(2012) 'axonas X offset plasma
d=GetUserDRO(2013) 'axonas y offset plasma

e=a-c
f=b-d

SetDro(0,e)
SetDro(1,f)

code "G0 X" &a
code "G0 Y" &b
While ismoving()
Wend

General Mach Discussion / V3.042.20 and over "Run reverse" problem.
« on: July 24, 2009, 07:52:44 AM »
Have you noticed any problem on "run reverse" button (OEM 279) on versions 3.042.20 and over?
Or something is happening to my pc?

General Mach Discussion / Enable 1-6 Signals. How to innitialize?
« on: June 17, 2009, 06:19:07 AM »
The enable 1-6 Signals are activated when pressing the Reset button.
How to make them not to be activated when Reseting?
Are these outputs being deactivated by the program (by itself) for any reason,
or only by a brain or a button?
If you have any idea, please share it...

General Mach Discussion / Non linear axis measurement...
« on: May 27, 2009, 02:46:26 AM »
This might be a strange post, but if you have any ideas, please share them.

I have constucted a rotating bracket (see the attached schematic).
The movement is not given on the rotation axis (red dot),
but by a gear-pinion sytem at the edge of the bracket.

I want to measure degrees at this axis.
The movement method causes non linear measurement.
As the bracket goes to the edges of the pinion,
i need to travel more for the same change on degrees.

Can i touch the measuring system?
Or can you think any way to solve this problem, without changing the moving method?

General Mach Discussion / When Homing limit switches do not work...(?)
« on: January 27, 2009, 08:47:26 AM »
I can see that while homing, the limit switches do not work.
Why is that?
Is there any specific setting about that?
The homes and the limit switches are in different input in my machine.

PoKeys / More than 20 outputs with pokeys & mach?
« on: January 26, 2009, 03:41:53 AM »
As i can see in the "output settings" on mach3,
there are no more than 20 outputs# to be used.
How can i have more outputs?
I just want to use my pokeys to activate and deactivate 40 outputs.
