I'm running a Nakamura Super NTJX and am using the B-axis to make an ID groove. I keep getting a 0319 "The end point command is illegal in drilling cycle"alarm. The lovely alarm book expands on this to say "Although ^i or ^k travel distance is set to 0 in a multiple reptitive canned cutting-off cycle (G74 or G75), a value other than 0 is specified at U or W

Machine is a 2 spindle machine with lower turret and upper B-axis milling spindle. Groove is being cut on the right spindle

Program is

G0 Z-.2
X2.29
Z2.39
G75 R.002
G75 X3.365 P800 F.004

Z2.353
G75 R.002
G75 X3.365 P800 F.004

It alarms out before it starts the first groove at G75 R.02

Thanks in advance for help,
Chris
 
Change the R's in the first G75 lines to R0020

I just typed in your program in my machine using negative Z numbers without the decimal points in the first G75 lines and it ran.

That doesn't sound like what the alarm is referring to though? But it ran on my Fanuc 0i-TD. Assuming you have a Fanuc control?

Sorry 31iA controller
Changed the R's, still alarmed out.
Z's need to be positive because its workng on the second spindle.
Deleted the entire section of code and rewrote it, no help.

G74 is pecking on the Z. G75 is pecking on the X. The alarm is mentioning "The end point command is illegal in drilling cycle" but your code contains X movements? Something is screwy. When you git this sorted make sure to come back and tell us what it was.
