OK I HAVE READ THE RENISHAW MANUAL ON THE 4TH AXIS MACRO AND IT SAYS THAT IT WILL FIND THE SURFACE ERROR AND ADJUST THE OFFSET BUT CAN NOT GET IT TO MOVE THE ROTARY (A AXIS) ON MY MACHINE WHAT AM I DOING WRONG???

T1 M6:
G43 H1 Z3.;
G65 P9832; PROBE ON
G0 B45<---- THIS IS THE CODE IN THE MANUAL IT MAKES NO SENSE MY AXIS IS A BUT I DON'T WANT IT TO MOVE TO 45 DEGREES
G65 P9810 X0 Y0 Z.250 F10.;
G65 P9817 X2.0 Z.250 B5.0;
G65 P9810 Z3.0;
G65 P9833; PROBE OFF
G91;
G28 Z0;
M30;

TO MAKE A LONG STORY SHORT I WANT TO PROBE ALONG THE X AXIS AND SEE HOW MUCH IM OFF AND HAVE THE PROGRAM CORRECT THE A AXIS ANGLE SO THAT I DON'T HAVE TO INDICATE IT EVER TIME.

Take a look at this pdf section 9-2:

I think it is what you are looking for.

thats where i got the example from but it doesn't work

[danh818]

The example is showing the rotary as a B axis. Just change it to A and input your desired angle as the number value.

Here is what I use to reset 54 A0 position when using a pneumatic 5c closer on my rotary.

it probes both point z1 - z2 but it doesn't make the a axis move after its done. i used g55 as a starting point for my probe so that i didn't smash it in to anything i just eyeballed the x and y and set them i did however probe the z position so the probe wouldn't crunch the knee.

i don't really understand #5224=0(RESET G54 A AXIS BACK TO ZERO) and how do you know #5224 is A axis variable

also you are using 9818 which is a Y location move i need mine to move in x because the knee is sitting on a rotary. so wouldn't it be a 9817 ???

[danh818]

Yes, I am using a P9818 to correct for an A axis located along X, so my probe travels in Y.
You need to do something with the values that your P9817 macro records. Hence in my example: #5224=#189 (recorded value from P9818 macro is set to variable #5224 which is the G54 A value.) You can find a list of variables in the machine manual, or look up the pdf online, for me its on page 127 & 128. You should also look at page 36 of the Inspection Plus pdf.

Hope this helps.

Dan im a little confused im on a horizontal Haas EC-1600 so to correct my A axis on my rotary table don't I have to probe in x???? My fault that might have been information I shoulda have included in main post. My rotary table lays parallel to my spindle. It has a knee bolted to it and im trying to probe the knee to make it straight every time I bolt it up instead of always having to indicate it in.

[danh818]

Yes, you should be probing in X. Although having said that I have no experience on a HMC. I run a VF2 and the program that I posted was mainly as an example of syntax. My rotary is mounted with the platter parallel to Y and rotating about X (the standard-ish setup of the rotary on the right end of the table), therefore I probe in Y to zero A.

You're on the right track, but you still need to do something with the data that the probe is recording in the variable register. Remember that the probe can only keep one data set in that register at a time, so you need to decide what variable to 'copy' the recorded value to eg., #5224=#189.

[heavenlykid]

Dan im unclear on what the variable does and what is page 36 of the inspection plus manual i have it printed out i don't have a pdf copy and my pages aren't numbered they are all in chapter like 1-1 1-2 etc etc. i think your talking about the variable outputs i can see all of those and i know what they mean but i dont understand is how to use the data it collects to correct the degree of the axis.
