  • Too Big To Function?

    Hey guys! Quick question if you don't mind.

    We just got a probe tip that Extends 30MM with a tip size of 5BY30MM. We run a program that requires the tip being set at A90B180 to measure a hole. But when it changes and moves, it errors out saying that there was an unexpected probe hit. So you have to wiggle the tip to get it back to function(keep in mind there's usual NOTHING around it. It's floating in air and errors out). My theory was that the whole thing is too big, seeing that the stem looked bigger and longer than our old tip, and the bulb at the bottom is waay bigger. Anyone have any ideas?
    I feel a lot better now that I've lost my mind.

    You probably need an extended force module.

      I run a 5by75mm on a med force module carbon fiber shaft on a 7,10,7
      i agree check your module

        Agreed. If it wasn't erroring when it rotated but just when it was moving you could probably get away with decreasing your speed to avoid 'air triggers'.

        I run a 4X20 tip with a 40mm extension on a medium force module all the time without trouble. If you look in the renishaw catalog it gives recomendations for max tip sizes/length for standard, medium, and extended force modules.

          Are you using TP20 modules? If so you need a medium force or extended force module.
          I used to be high on life but I built up a tolerance.

            Sounds like you need to slow your speed down. I'm currently using a 4mm 40mm long with a low force module without any problems.
            Out of all the things I've lost.... I miss my mind the most!

              Go to a medium force module I run 40mm steel ext. 5X20mm tip no problems
              move speed 25 touch speed .75

                Yes, I am using TP20, but I am not exactly sure what modules are in PCDMIS...a little help?

                How would I access them to change them? Are they in the probe build?

                  What color is the plastic on the module???

                    Its the removable end of the probe secured w/ magnets. The type will be written on it. Make sure if you change your touch speed to apply it to every part of the program in which you use that long probe and to recalibrate at that speed as well.

                      The modules are what the stylus screws into. There are low,medium & extended. They are 900 bucks a pop from renishaw. With your length you probably need the extended module or try carbon extensions & slow the machine down

                          It says TP20 STD FORCE
                          5M0124

                          So I'm guessing that's standard force? How would I make sure that that force is being used in the program?
                          And by the way, what does the 5M0124 mean on the module?
