Need Help!! With school project
« on: March 29, 2010, 09:34:36 PM »
Sorry if this doesn't work!!
I'm having a little problem with the M98 & M99 codes. We are doing a pattern of 3 in a row of the letter (I). And if I put a end of program (%)
at the end of the M99 I just sits there and repeats and repeats then I end up canceling it and then I only get one (I). And if I put a L3 on the first M98P0207 I get three patterns at .435 inches apart which they should be .900 inches apart. What am I doing wrong. So here's the code. And I'm using Mach to run this. (trying to run this) and the machine at school is a HAAS M1 mill. Hope the picture work to get a better idea. And I hope this makes sense. Thanks

Search the forum for G52 command, this allows you to write your sub in absolute and call G52 X? Y? as local datum point. Use G52 X0 Y0 to cancel the shift before you issue the next.

Thanks Graham
   I will check out the G52 search. At least I have a direction to go and see if I can get more confused than I already am ;D.
Thanks again
