Greetings Guys; Dean, I have that probe built, many thanks for the idea, and now waiting on digikey for the optical stuff, I bought 5 of them so I can make some limit switches too. Here I'm working from memory, the printout is out in the shop, so I could have the numbers wrong. One concern I have with using the G38.2 function is noted in my copy of the rs-274d manual, and it doesn't say much about storing the results except to note something about the 5199-5x00 range, which I'd assume one could access via the Z#5199 etc syntax. What strikes me as a rather severe limitation to this concept is the apparent lack of just using a logfile for the results, which could then be made into a surface mesh for visual checking in a wireframe program, and finally manipulated back into a gcode file, the idea being to take a pattern to carve, where you only have the x/y params, and by comparing the x/y params to those in the probed mesh file, find the closest matching x/y position in the surface mesh, interpolate and add the appropriate z values to the otherwise 2 dimensional file. The end result probably to be carved with a diamond tipped burr moving at, in my machine, about .01" a minute so as not to bend or wear the burr before the job was done. The spindle max is 2000 rpm for this machine. I'd like to be able to write a gcode program to probe say a floor plate from my hunting rifle, on about a 0.010" grid, so the result mesh is going to be around 1.5" by nearly 6". That's a boatload of points, and if not made acessable in a file format for further use, seems rather pointless in the end. Is there a solution for this apparent problem, possibly even conceptual because I'm not visualizing the problem correctly? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
