Ron,

The attached .JOB file shows two operations. I am doing a .625 hole on the top and bottom faces of a 1" sq tube using a line of holes using the circle function. The first hole operation has Ztop of 0, Zdepth of -0.130. The second operation is supposed to have Ztop of -0.875 and a Zdepth of -1.100. The operations list seem fine, but the GCode is not working. Ztop on the second cut is still 0.0 instead of what I specified.

That is NOT what your operations show. (;-)  Both have a Ztop of 0.000.

Just a thought, (;-) TP

You mean this operation? Hence the bug report.

Ok, I just found a bug. We added Ztop but forgot to add it to the Job string. Its in the internal data struct but not fully added to the code.

thanks

Ok, that was an easy fix. Brian will be updating the installer file tomorrow.

I checked and it was wrong on all 4 hole operations.. All fixed now

Yay! I will watch for it.

I just looked at your job file and it shows Ztop 0.000 for both operations ??

(;-) TP

I just looked at your job file and it shows Ztop 0.000 for both operations Huh??

yes, that was the problem. Ztop was not being saved in the job file, and it was not being passed to the gcode generator.  The same thing was happening to all 4 hole operations.

There is a bit of a problem on those ops. The Drill cycles do not have a parameter for Ztop, they always start at Z=0 Only the circle and circle pocket can have a non zero top.

Ron a Drill cycle can have Ztop anywhere +/- it does not have to start at Z0 The ztop is defined before the Cycle call and retracts back to where ever you want with the R value.

The G98/99 also control the R values so you can have Ztop defined at teh start AND the G98 will retract back to that point in lue of the R value.

NOW IF you do not define the Rvalue then Ztop will be Z0 and the retract will be Z0 which is NOT always correctly  applied as to G98/99 mode
 
Just a thought, (;-) TP

Ok, we already had that in the code R is set as wxT(" R ") + gcFmt(a.Ztop + jobS.Clear)
