I'm getting a strange SUM error on my VMC40 w/88HS control.

N1 O103 ( HEAT SINK)
N2 (NO SPACERS, 1.25 PROJ LH)
N3 G90 G80 G70 G40 G17 G0
N4 (SPOT DRILL)
N5 M6 T6
N6 S2000 M3
N7 H6 Z 0.5 M8
N8 G82 G99 Z-.37 P10 X0.15 Y-0.24 E1 F20.
N9 X3.4
N10 Y-4.24
N11 X0.15
N12 G0 Z 1.
N13 M5 M9
N14 G80

The program stops at line 12 and when I do a SUM I get the message "Bad Z or...". The strange thing is that the coordinates displayed in the SUM message are X -3.452 Y -1.398 Z -9.797

Anybody got a clue where this is coming from and how to correct it??

You have a space between your Z and the Z number:violin:

Unfortunately that isn't it. I had copied and pasted program from a spreadsheet but when I checked the actual program in the 88HS there is no space...it's typed as Z1.

[carbidecraters]

Oh, sorry you need to put your G80 in before a Z move

[rdoty]

Just to make sure I went out and deleted line 12 and re-typed it. No difference....still get "Bad Z or R0 in canned cycle call. N=12"

[carbidecraters]

Ok so you dont have a R number for a return plane that would be R.5. Add that.

the R value shouldn't be an issue here since the fixed cycle does all the positions before the fault. a G80 inserted between N11 and N12 should fix it. at N11 you are still in the fixed cycle and you can't drill upwards. the Z always has to be lower than your initial plane. this would be my program if you need the fixture offset.

Cancel your drill cycle at line N11.5. the Z move at N12 is telling the control to drill upwards and it can't do that.
