Hi all. first post here... Big thanks to all the contributors of this forum, i can spend days reading discussions here.
I have a renishaw omp40-2 on a Haas vf2ss with OMI and would like to speed up in cycle probing using 9812, 9814, 9834, etc.
Currently there is a G04 P250 at the beginning of almost every subprogram, including 9832 (turn on probe), 9833 (turn off probe), 9810 (protected move) and the measurement routine itself. all those G04s add up and slow down the probing routine considerably, especially if you are doing multiple routines. is there any issue with just removing the G04 from all of the subprograms? what is it there for?
Another possibility is optimizing the probing feedrate with 9836, however, they have seemed to omit that program from my control?? what the hell, Gene? Inspection plus manual says "defaults are good enough for small/medium sized machines". :willy_nilly: I would like to try it at least. I will call up renishaw tomorrow AM and see if i can get them to give me 9836.
Finally, any discussion on one touch vs two touch probing? I've read Renishaw TE412
(link) which suggests two touch probing for accuracy. This is because the machine has a 4 ms (typical) loop time and so the measurement uncertainty scales linearly with feedrate. However, TE412 also talks about another type of skip which interrupts the controller instead of waiting for it to refresh allowing for an immediate response (and repeatable so it can be calibrated out). Is this a hardware deal or software? The second method would allow for single touch probing while maintaining accuracy, but something tells me will not be a possibility with a Haas.
