This takes the XY perimeter tracing routine, and turns it into a surface tracing routine that works in the XZ plane.I began writing Probe-It to be able to provide functionality in Mach3 I didnt see provided by any other options, even after much searching in forums and on the web.

It serves one simple yet important purpose Test your probe out and verify the big LED on the Mach3 screen lights up when you activate the tip before you do any probing This verifies your probe hardware, wiring, and Mach3 portpin setup. When you create a calibration table, you probe the ID of an accurate and round gauge ring that you provide the actual measured inner diameter. The probe routine builds a table of compensated tip diameters for every 10 degree angle directions. The compensation can correct for probe trip deflections, backlash, etc and results in the ability to probe parts and perimeters very accurately. You can select from two methods of calibration depending on your probe. If your probe tip is mechanically centered to the shank (Prefered), then run option 1 to create a table that compensates for tip deflections and backlash. If your probe tip has mechanical runout, use option 2 to create a calibration table that includes an XY offset for the tip to shank error. This method is less ideal, as you must re-install the probe at the same angle everytime. In addition, you must be able to center your spindle to the gauge ring BEFORE running the option 2 calibration routine to get the correct offsets measured. All of the routines provide dimensional measurement info (CMM like usage) and the option to zero the axis to probed features (setup). Data may be saved to a CSV file (CMM like measurement recording) or to a DXF to build up CAD file of probed geometry. You can also rotate all the probing routines by an angle entered in the part rotation DRO. Artsoft H 3 Cnc Program Full For ReproducingUp till now Ive not found an easy way to get accurate 2-D profiles recorded into something usefull for reproducing a 2-D or 2.5D type of object, which is mostly what is required for reverse engineering of simple parts The 3D bed of nails routines in the bundled Mach3 Wizards are great for probing away at a coin or a toy car and giving you a point cloud, but if you accurately want to reproduce a profile shape, say a guitar body, or hole patterns in a plate, etc the bed of nails route wont really get you there. Points recorded are either saved to a CSV or a DXF file (or both at once). The probing routine attempts to always probe squarely against the perimeter of the object and used the tip correction look-up table to be as accurate as possible. When the routine runs into an abrupt change, it will attempt to interpolate the corner as a 90 degree direction change and record a point at the assumed intersection. This may not be fully accurate, but it is easy enough to edit the DXF files to fix the geometry, and the interpolated guess points are indicated by circles to highlight them. ![]() The only thing done after saving the file from Probe-It, was to open in ACad, and fit a circle to the wrench profile using 3-points so that a diameter measurement could be made.
