Program on lathe stops on random gcode was created by Anonymous

Hey
I just recently converted my old lathe to a CNC
i decided to use LinuxCNC and now when i run a Program it randomly stops at N23.
If i remove that line it runs till it gets to N29, then N35... and so on.
What am I doing wrong

Are you missing the feed rate ?

Clive is right, there is no feed rate set anywhere in that gcode so it will stop at any G1 it encounters, but it will spit an error saying exactly that it is missing a feed rate value.

Even if i ad a F100 for example at the end of (N21 G0 Z1.164) to make it (N21 G0 Z1.164 F100) it still stops the program at that line.

Do you have feed override down at zero?
Does it happen with just this program?
Can you jog ok?
Does the machine home ok?
Does this MDI command work? G01 X100 F100

I think with G96, constant surface speed, feed must be f/per rev. F100 or F200 could end as rapid move or is just too fast to be done.
