no safe Z in local system rotated
« on: December 05, 2010, 10:44:02 AM »
Yesterday, I had the opportunity to take advantage of the LOCAL SYSTEM ROTATED feature as offered on the MDI screen. I rotated to 180 deg. To my surprise and to the breaking of a tool, both the STOP and GO-TO-ZERO functions did not use SAFE Z. After double checking the safe Z status, I confirmed that the Z axis did not change from its current position when using either of these functions.  After rotating back to 0.00  degrees, operation returned to normal. I did not try any other angle. 

Is this the correct operation? I am using the latest locked-down version (Mach3 R3.042.040)

Thanks, Bill

yOu are correct, it does not work . Never did. You should have gotten a message stating that safe Z does not work in Coor Rotation. There are other things that don't work with G68 as well. IT would be perfect for plasma cutting BUT a major function like RefZ does not work when rotated. Most cutters use the RefZ to find the TOM.

Now along with SafeZ and RefZ I can,t figure what it has to do with G68 THe Z is NOT rotated just X/Y. I guess Art just wanted to make it simple to develope. Shame thought it does limit its use.

NOW with all that said what did that have to do with you crashing the tool.  An old saying in CNC maching is IF you programmed yourself into the box you need to program yourself back out of the box BEFORE your next move(;-) 

Been there before and that is why I never use the safeZ it helps you develope some BAD habits in programming AND will crash a few tools all on its own from time to time.
