I got my CNC to read and accept code from the Behind the tap reader module. I can get code into the cnc.

Now I just sent a simple program, like

G20
G28 X0 Y0 Z0
M3 S1000



But when I try to start the program in memory mode, I get an alarm 14.


Sometimes it will say

2.14
5.14
4.14

but always alarm 14. Any Ideas?

what control is on your machine ?

Have you tried hitting reset when you go to memory mode. I get alarm 14 when I load a program in edit and then switch to memory mode without pushing reset. Simple but gets me quite often.
