General Mach Discussion / reading excel files in Mach 3
« on: October 06, 2008, 10:16:12 PM »
I have several excel files, one with  x y pairs with several thousand points for linear interpolation and another in polar coordinates in degrees and y axis.  How do I import this into the g code editor? I quess what I am asking is how to import excel files into Mach 3 or how can I convert these files to g code that can be used by Mach 3?

Graham,

I downloaded latest Mach release and installed and now formulas are working as they should.  Now Maybe I can figure out how to use them.

Thank you once again for your help.

Graham,
YEs, I am using licensed version of Mach 3 and it has been working fine except for this formula feature.  My version is 2.60.  I thought that I had updated just a couple of weeks ago with lockdown version.  Boy It looks like I might be out of date.

I really appreciate the time that you have spent with me today.  I'll see if I can reinstall & update.  It looks like my frustration has been in the basic malfunctioning of this feature in Mach.

Thanks,

Woodeye

Graham,

I rebooted computer and Mach 3 set up formula for X as X*2 enabled formula and then entered G00  G91 X1 in MDI and I got a move in A of 1, go figure???

Graham,

What I meant to say is that is what I show except for DRO

yes, that is same as what I show also. However when I enter the test I get the error I mentioned previouslly and when inputing in MDI the formula is not applied even though I have it enabled.

Graham,

I tried the formula function X*2 as suggested by entering this on the line for X in the formula axis correction box under functional cnfgs and it doesn't work.  I tried it several times and also the same formula for y as Y*2 and it either does nothing or returns a dro as if no formulas were enabled.  Also strange results where even though X1 is entered in MDI, DRO shows motion in A.  When attempting test in formula axis  correction box I get error found on position 1  General parser error blocked!  So I apparently have a problem with Mach 3 and using the formulas.

Thanks, Woodeye

 I used the circle as an example to try and make myself understood but I wish to go beyond that example to patterns that might encompass the entire surface or most of it and that would require rotation of the A axis due in part to the fact that my cutter would be restrained by my X-Y table (Taig mill) upon which my rotary table (Shurline) is mounted. By incorporating the A axis motion I figured that I could generate patterns that would wrap around at a given distance from center.  Don't misunderstand me, I really do subscribe to the kiss method as well and am in no way wanting to complicate things beyond what they already are.

Could you provide guidance or where to find information in regards to using the axis formula corrections in Mach 3?  Is there any written material on this anywhere?  I mean, like do I enter a formula in the formula axis correction line as provided in the dialog box under function cfg's and where do I find the format to use.  I envision formulas such that I could state that X is a percent or fraction of Y or visa versa and when I generate a code that would otherwise create a circle, I get an ellipse instead.  I have tried in vain to enter any sort of formula that would affect any motion in Mach 3, all I get is errors in my attempts.  What I am looking for is basic information in using formulas in Mach 3.

Thanks, Woodeye

Graham,

Ok, I have that.  Now, imagine that I want to cut a series of these 20mm circles around a face that is able to rotate on the A axis, this would form a ring of 20mm circles, the spacing and overlap dependant upon the number of these 20 mm circles that I cut, as well as the radius of these circles from the center of the rotation of A axis.   I know also that I could simply advance A for each subsequent 20mm circle, but is there not a way to coordinate the motion of A and Z to scribe the circle?  In other words substituting the motion of A for Y, which in itself being rotary, would require some sort of interpolation being that the feed would be constantly changing as the cut moved near center and out again.  I just thought that the formula axis correction could be used to make this adjustment in order to scribe a circle on the end of a cylinder held in a rotary table.

Thanks, Woodeye

Graham,

I am also a newby when it comes to this forum and how to navigate and get around.  I noticed that there is an icon that show you on-line, how does one set up a chat session or is this taboo?  Struggling here to come on board.

Thanks, Woodeye
