Re: [Emc-users] touch probe routines
My preferred probe calibration protocol: clamp a known diameter hole (ex. dial bore gage master) to the machine table determine XY location of the hole (test indicator in the spindle?) with the probe in the spindle use a calibration routine to determine where the probe calculates the hole XY location and the diameter of the probed diameter the calibration routine uses the known diameter of the probe tip, the known diameter of the hole, the dialed in XY location and the probed XY location to determine the apparent diameter of the probe tip and the adjustment values to correct the probed XY location to the dialed in XY location. These values are saved for future use. I don't have a probe on any of my EMC2 machines or I would work on this protocol. thanks Stuart -- dos centavos -- All of the data generated in your IT infrastructure is seriously valuable. Why?

Re: [Emc-users] How can I create my own functions table for named subroutines
In the past I have thought that it would be great to have a feature in EMC2 like the C pre-processor, that would do some automatic replacements to allow the original G-code to be more readable. It seems like two threads here can collide, and the solution for the thread on substituting A for E could give us a solution to the named subroutines problem. the previous solution used filters in the ini file: This is my filter section in .ini [FILTER] PROGRAM_EXTENSION = .png,.gif,.jpg Greyscale Depth Image PROGRAM_EXTENSION = .py Python Script PROGRAM_EXTENSION = .gcode Extruder gcode png = image-to-gcode gif = image-to-gcode jpg = image-to-gcode py = python gcode = E2A This is E2A that was run from outside of AXIS before #!/bin/bash sed -e 's/\( E\)\([0-9]*\)/ A\2/' $1 Guru comments on this? Here we just have to adjust our sed line to get editing scripts from a file like so sed -f subroutines.sed $1 now we can have scripts to replace text subroutine names with the numbers EMC2 seems to like so much, IE: s/rectangular-pocket/500/ s/peck-drill/501/ s/leave-a-tab/502/ Now you can use whatever names look good to you, and before EMC2 sees the code, it will be changed to a simple number. It will only replace the first instance of the phrase on each line, so if you put the subroutine name in a comment at the end of the line, it will survive sed, but will let you keep track of subroutines in AXIS.

I've seen these edge locators with an inside corner and a hole centered over the intersection of the sides of the corner. I don't know how to make one of these fixtures accurately. A good one is probably somewhat expensive. Steve Stallings had a $120 touch probe made by Wildhorse Innovations (I think he paid $140 but they have reduced the price.) It is modeled after the patented Renishaw probe that recently expired. It has a steel ball machined on the end of the probe rod. I figured I could find a ruby ball with a drilled hole somewhere relatively cheap and make it even better. Anyway, Mach is set up with some routines for probing edges and the center of holes, and this has apparently been done to some extent in EMC, also. There seems to be a hole finding routine in nc_progs. The center of a hole needs no information about the probe, just that it is centered to the spindle and the ball is spherical. To pick up an edge of a part directly (without the above-mentioned corner fixture) the routine needs to know the diameter of the probe ball. And, then, it would be most convenient if it could do the same thing the touch-off button does in Axis, for both X and Y. This would be really convenient, as I always fumble with whether I should enter +radius or -radius for the touch-off value. I have to always do G1 F10 X0 Y0 after touching off to catch when I have done it wrong. Jon -- All of the data generated in your IT infrastructure is seriously valuable. Why?
