General Mach Discussion / Re: Set Z to zero automatically?Auto tool zero questions

« on: February 20, 2008, 01:27:42 PM »

   Whoops, my error  on the lack of updating the ZProbePos ..I had OEM trig 1 set to the same pin for cycle start. 
I should have guessed that when I saw the start led flashing at the same time as the probe led    but I figured it was another mach "feature"

Thanks for that Greg,

though there could still be cause for concern..

I've been testing these scripts just letting the G31 run to the end and of course it still thinks its done its job, I think some more scripting needs putting in there..

Another thing is that if your dro is reading a large number then G31 Z-20 is a long way before it stops - if it can get there, so that needs to be incremental. If it's not incremantal and your dro is reading smaller than -20  i.e, -100 then it goes up 

 here's what I put..
>
If GetOemLed (825)=0 Then
Code "G91"
Code "(Put Plate in Position)"
Code "G4 P5" 'Time to get to the z-plate
Code "G31Z-20 F" &ProbeFeed
Code "G90"
While IsMoving()


But this assumes that the machine was in G90 state before hand and wants to go back to being G90

Is there a list of variables in Mach that hold the current active G codes? That way it can be collected before the start of the macro & put back after the macro

There's gonna be that day when you're not using abs and it's bound to be an expensive tool/job 

Shoving different numbers in the dro and trying out the macro usually works  I can't put my finger on what exactly how to replicate it but stepping through the macro I found that when it goes haywire it hasn't updated the ZProbePos variable, I'll try some more to make it repeatable but early tests seem to indicate that it screws up if I don't jog the Z axis after changing the dro.....  oh ver 3.0 arts last

Has anybody else had this?

Questions/problems.... sorry guys...

I don't know if it becasue I'm playing with the script on a laptop without the Mach driver installed (laptop don't have a PP so no point!) As I understand a G31, it moves the given distance, in the case here 5, unless the probe is triggered. I'm finding that it just keeps going, anyway I'll try it on the machine shortly...

Some other bits that strike me are the fact that the script puts the machine in G90 and doesn't take it out again - ok easily added, but is there a catch all "something" I dunno what, to check and store what all the active G & M codes are and then at the end after runing the script put them back as they were.

I did not know what to expect when i opened that Dwg.
So if you have a knob I have a Cannon   Here is the Dwg. I have trouble with and as far as I can see it has the correct perameters.

ah hum, yes perhaps should have given it a better name 

I can't see anything in your cannon when I open it with autocad 14 but I can see it when I drop it in Vcarve - The problem could well be that there are other things in the file as well, there's things in it that look like a light bulb and light written on them amongst other things..

yosefi83 - opening your file in Vcarve all I see it a load of circles

here's a sample dxf for you to open it a dxf viewer, it's just a top half profile and that works for me, as long as it's one continous string of lines & curves it works

hmm a chuck representation would be good, though I guess that will come at revision149

There doesn't appear to be anything in the dxf...

Mornin' (wel it is here!)

I like it...but, there's always a but;),

after you've changed the stock size etc the mouse dissapears and I have to wiggle it about to find it again

Nice triangles but when the stock is nearly the same size as job it's ahrd to select one of them.. how about putting the stock arrow on the other side of the ruler?

and.. when I bring in a dxf it doesn't drop in as the size I drew it - is it me or the s/w?  seems to me that if I bothered to draw a shape I would have drawn it the right size and would want/expect it to be the same size in LT

perhaps a box popping up on loading asking whether it's imperial or metric and where do you want the origin - chuck end or free end

If I try to change the diameter of the job it says enter max dia bigger than what I drew it as, therefore I can never make what I drew, well ok adding 0.001 won't make much difference

and numbers not in the boxes as above

btw whats that scale bar sort of thing up on the right hand side?

I await the next version...at this rate you'll have it done by the w/e

OK,

the Z..
The numbers stay the same it just shrinks if you put a bigger stock size in & vice versa, I suppose thats natural

those origin arrow don't show up very well in green against a blue background

I've just imported a dxf but it didn't import it the size it was drawn, is there something I'm missing?, I changed it ok but it's not very lazy (ok I know it's early days yet ) oh length was ok

Here's another one - when stock is same size as job the pentagon goes brown.
A box showing max dia & length would be handy while I'm on  a roll... how about a origin splot you know the white circle with 2 oposite quarters in black.

bonne chance

psst the help file's a bit thin

Hmm, I'll try & get the Z to change and let you know how I did it

Let the user (god bless them ) define his stock sizes. but otherwise that's exactly what I was thinking

Hi Art,

Yeah that done it!

my 2cents..

change the pentagons to triangles pointing at the scale and make them dragable, I found myself wanting to move them just to see what happened to the image

Here's an idea.... have a table of standard bar sizes (metric and for those across the pond, imperial so 2 tables, user definable) and dragging the triangle jumps from one stock size to another and inicates the current size of stock when the moves moves over the triangle

When you click on the pentagons (now redesigned as triangles ) to change the size make the numbers in the box highlighted so you can instantly enter a new number (hey it is supposed to be lazy )

I found it unnerving the Z scale changing when I altered the stock size etc - though I'd changed that as well!

go to it art! looks like a fun thing 2 do
