General Mach Discussion / Mach Version 3.043 G52 does not work
« on: March 14, 2009, 02:59:39 PM »
I just installed ver. 3.043 and now my G52 offsets no longer work.  Anyone else have problems with G52?

General Mach Discussion / G52 with Tool Radius Comp (G41)
« on: June 22, 2008, 12:58:20 PM »
Hi All,

I am new to Mach3 and I am trying to get tool radius comps working within a G52 offset.  I have reviewed some posts here and understand that the display in Mach3 does not show true G52 offsets during a cycle run.  However, the issue I am having occurs in the machine coords and does happen during a real machine run.  I have slammed the limits :-[ .  Basically, for this exercise I am trying to machine a series of 4 circles in wood at 4 locations.  When I run the code below without G41/G40 everything works fine.  However, when the tool comps are included in the cut code, the first part runs fine but the parts run under G52 offsets have a shuttle in X just after G41 is activated.  The tool does a rapid shuttle to the original offset position and back before running through the circle code. You can see the event in the graphics window and by watching the machine coords.   I appreciate any comments.

Thanks,

Eric.
