I'm glad you got this working, but you've lost me.  Adding the values as you show shouldn't generate a useful position.

Consider the below hole; Yellow is the ref point, green is the selected point and top of stock, and red is the depth 

    

I setup a drilling postblock to mimic your math

pdrill$
	"Ref. Z position (Abs.)             : ", *drl_ref_z$, e$
	"Selected Z position (Abs.)         : ", *drl_zdrl_z$, e$ 
	"TOS Z position (Abs.)              : ", *drl_tos_z$, e$
	"Depth Z position (Abs.)            : ", *drl_depth_z$, e$ 
	*e$
	"Ref. Z position (Inc.)             : ", *drl_sel_ref$, e$
	
	zrefhgt = drl_ref_z$ + drl_sel_ref$
	*e$
	"Sum of drl_ref_z$ and drl_sel_ref$ : ", *zrefhgt, e$

And that resulted in the following output.

Ref. Z position (Abs.)             : 60.
Selected Z position (Abs.)         : 50.
TOS Z position (Abs.)              : 50.
Depth Z position (Abs.)            : 20.

Ref. Z position (Inc.)             : 10.

Sum of drl_ref_z$ and drl_sel_ref$ : 70.

 

I don't understand how a value of 70mm is useful.   

Are you using a 5 axis drilling toolpath?

I think you are making it more complicated than necessary. There are variables (pre defined) available to do what you want without calculation. Pay attention to incremental and absolute.

As Zaffin_D suggested the documentation is indispensable here. Especially the newer (after 2017 or 18) portfolio has a dedicated drill cycle section. You need to see what pre defined variables are available on the custom drill NCI line

The predefined variables are not mapped correctly. Some are absolute and some are incremental adding the incremental values to known absolute reference values make them absolute as well. turns out this was a mapping issue and my calculations are working. 

 drl_init_z$   (clearance height)                          Mapped value
 drl_sel_ref$  (retract height)                            not mapped
 drl_sel_tos$  (top of stock)                              not mapped
 drl_ref_z$    (referance point in space for top of hole)  Mapped value  
 drl_depth_z$  (hole depth)                                Mapped value

drl_sel_ref$ & drl_sel_tos$ get output from mastercam as inc values.
I am using the calc's below to calculate these variables based on a mapped value
 
zrefhgt = drl_ref_z$ + drl_sel_ref$
ztoshgt = drl_ref_z$ + drl_sel_tos$

FYI I'm new to post writing and open to advises if I'm doing it wrong. 
 

I am trying to write a custom drill cycle to do some 3+2 moves and probe points on a surface. I am using a 5 axis drill tool path with a custom drill cycle.

I have it working mostly how i want to but the Z values are coming out wrong. Any advice would be appreciated machine is a Mazak Variaxis.

now I get this output from the post and it still falls over when it sees letters, apart from the Groupcom it's pulling in from somewhere. 

(groupcom 2568542.)

Hey Team, 

I am trying to output the Tool manufacturers code from the tool settings into the G code. I have it working when the tool code is numerical but when the tool code has letters in the code it stops outputting after the Tool manufacturers code after the first letter is hit. 

ex. 78987t8987    post will output 78987 and stop. 

pardon the bad coding I am hacking and learning as I go.

Thanks in advance.  

fmt  "TC=" 25 groupcom     # out put the tool_op$ Manufactuers code

if prmcode$ = 20002, groupcom = rpar(sparameter$, 50)

It has been reported and they are looking into it. 

I have sent this to QC at least 5 times

Hey Gs

I see the error from time to time and just close and reopen MC, It's annoying. today I sore a case where every time the simulator launched the error occurred.

"Unknown error has occurred " (most brain dead error name ever) 

This issue was caused because all of the machine simulator default machines were removed from the MC2020 shared machine sim folder. 

The  "5_5AXGEN_VMCTTAB" cannot be removed from the folder. It is used by the Mastercam verify machine simulator as a default machine. 

put this one machine back in the MC2020 shared machine sim folder and the simulator works again.
