HELP error calculation deflection matrix

Error calculation deflection matrix after completing calibration for some tips. what is it?
  • After the lower matrix calibration, I'd check the reset tip button on the qualification dialog box.
    That returns all tips to the theorical nominals before calibrating.
  • Do you get this message after "lower matrix is completed"? Please do a machine start, then press OK, but wait...." then I get a SHUT down or OK prompt
  • So your options are shut down or OK, right? So I think I would wait 15 seconds or so and then press OK. Sounds like this is the same message you get anytime there is any probe deflection error or anything like that. I always just say OK to this message. This kind of thing changes all the time with different versions so, as I said before, you might be seeing different prompts than what I would see in 2012 MR1. Whenever I have done this the procedure has been very straightforward.
  • here is the message. I did like you said this time, without doing a machine start after lover matrix completed, altogether Hexagon tech told me that it is wrong and I need to follow the exact instructions.

    What about the reset probe option, is that applies to each probe file? So do you do this to each probe or you only do this to the first one?

    That IS wrong! I am saying the same thing that the Hex tech is saying! You should follow the prompts and do exactly what they say!
  • Ok I will redo tomorrow. Thanks for all your help
  • I still get the calculation deflection error, not with all tips and not with all angles, just some. I recal with slower touch speeds and speed and it works.
  • Ok, so how about the other suggestions that were offered here? Is your stylus heavy or unbalanced? Have you checked the ruby to be sure there is no damage or that it isn't loose? Have you cleaned and oiled the kinematic spheres on the puck? What are you using for a touch speed? If you are using a touch speed of 2mm/sec and your stylus meets the length and weight requirements you should not be having this problem on any angles.

    You should also check that you return data setting and other probe options settings all meet the manufacturers specs.
  • I had this problem intermittently for about a year with a LSPX1M with 100mm extension and 1.5 X 20 probe. DEA controller. Service guy had to tweek a couple of parameters in controller that had to do with timing of wrist rotation or something like that.
  • Ok, so how about the other suggestions that were offered here? Is your stylus heavy or unbalanced? Have you checked the ruby to be sure there is no damage (YES) or that it isn't loose (YES)? Have you cleaned and oiled the kinematic spheres on the puck? ( cleaned with alcohol, not oiled, what kind of oil do you recommend?) What are you using for a touch speed? If you are using a touch speed of 2mm/sec and your stylus meets the length and weight requirements you should not be having this problem on any angles. ( I use TouchS-2mm/s, MoveS- 250mm/s) All my styluses under 105mm.)

    You should also check that you return data setting and other probe options settings all meet the manufacturers specs ( I did chk it with Hex. service guy over the phone) .


    Thank you
