VB and the development of wizards / Re: About a delay routine with G4

« on: April 12, 2008, 02:01:01 AM »

Sorry, i will be more specific.

I want to create a time like "preheat time" for an oxygen torch.
So at the starting point of the shape that i want to cut i put the following code:

• ActivateSignal(Output 1)
• wait = (GetUserDRO (1037)*770)
• code ("G4 P" & wait)
• followed by the code, eg: G03 X100 Y100 I25 J25

This delay routine works fine (for values from 0 to 27 at the DRO)
and the user can "escape" ( i mean can stop the Dwell) by pressing DoOEMButton(0) or with DoOEMButton(288).

When a value greater than 27 is put, the Output 1 is activated,
but the movement never starts (which shows to me that hangs to the dwell).
At the same time if i press "DoOEMButton(0)" still does not do anything.

Only if i press "stop program" it stops and i can start from the beginning.

So, my problem is why cannot perform Dwell, when 28*770=21560msec and over is set.

Any information would be helpfull...

VB and the development of wizards / About a delay routine with G4

« on: April 11, 2008, 05:39:41 AM »

I have made the following routine:

wait = GetUserDRO (1037) * 770
code ("G4 P" & wait)

But when i set in the 1037 DRO value bigger than 27, the system enters the routine and never stops.
If the value is lower than 27 works fine and by pressing the DoButton(0) escapes the routine.
With 28 even the DoButton(0) does not stop the routine.

I also did the following:

Dim wait As String
The reaction is the same.

Any ideas?

General Mach Discussion / Move in X and Y axis with a button.

« on: April 08, 2008, 04:10:30 AM »

Good morning!
Please help me on the following:
By pressing a button, i want to move in X and Y axis a standard distance and then zero both axis.
All i want to do is: to place a laser pointer above the machine's head, pointing at the material and showing where the 0,0 point should be.
Then i will move the laser point to the wanted 0,0 point and i will press this button described above.
So, the machine will move to the original head's 0,0 (where the tool is positioned) and will zero the x and y axis.
Any advice would be helpfull.
giannis.

« on: April 03, 2008, 03:36:54 AM »

Hello everyone!
I need some help related to the slow jog button.
With OEM button 111 and 112, i can change the percentage (%) of the jog speed by steps of 5% up or down.
The guestion is how can i change this step to 10%.
And how can i make a button that will set -lets say- 20%. Then by pressing onother button, to go back to 100%.
Thank you in advance!

General Mach Discussion / Re: How to calculate the kerf width for plasma cutting?

« on: September 14, 2007, 08:26:56 AM »

I did exactly what you suggest above.
But now the program stops at the G41D1 command,
by showing white the next command on the screen,
and with no error generated. Just stops there waitting.
Should i make any configurations? (I tried a few things in the general config menu, but nothing...)
  Please help!

Maybe i cannot understand exaclty what you say.
I put in the code before the G41 or G42, the G54 command:
.
.
.
G54
G41
.
.
.
I set at the fixtures (that very helpfully you uploaded) the kerf width that i want for axis X and Y.
Then i load the code.
The shape is a rectangular 200x200 mm.
So, i am expecting the cursor to go to 3mm around the shape (if the fixture is 3mm) which means 203x203mm.
Am i right?
Does it need anything else?
Because it does not work.

First of all thanks for replying.
OK, my nesting software gives G41 when CW and G42 when CCW and G40 at the end.
So, now, mach recognizes the kerf on/off and stop? And where can i set the kerf width?
Because (if i understand well) kerf is the gap that plasma leaves on material through cut.
So, if i have a rectangle shape of 100 x 100mm and the kerf width is 3mm, the path should be at 103 x 103mm,
and the final cutted rectagle will have the 100 x 100mm.
Can you help on this?
