I am getting this alarm and have honestly no idea why. Here is the program


( FACEMILL )
( PROGRAM NAME: AFM1 )
( DATE=DD-MM-YY - 19-07-11 TIME=HH:MM - 11:53 )
( X ZERO IS LEFT EDGE OF PART)
( Y ZERO IS BACK OF PART)
( Z ZERO IS LOCATING SURFACE)
G0 G90 G17
G15 H02
N10 M01
NAT2
N20 S10000 M3
N30 G0 G90 X-.375 Y-.1875
N40 G56 H2 Z2.
N50 Z1.1 M8
N60 G1 Z.9 F120.
N70 X1.81 F80.
Z.8
X-.375
Z.76
X1.81 F60.
Z.75
X-.375
N100 M5
N110 Z8.
N120 A0.
N130 X-22. Y12.
N140 M02


I have also included pics of the setup I am using the vice on the right.

It alarms out on the boldfaced line. All I can say is WTF? It is an Okuma VMC4020 with and OSP 100M

Thanks!!!

VMC4020 with and OSP 100M
check the "info" button (must be most left right bellow display) maybe some more information

Machines these days have "look ahead". The line the program stops on is usually not the line that is causing the alarm. On line 120 I see a call for A0. Does this machine have A axis enabled?

[Algirdas]

1. F60 could be too much for A axis.
2. A axis has some limitation ... Don't remember exactly now. It can't be rotated more, than ... times one direction. Must be rotated oposite or some workaround

Hey thanks guys it was the A axis trying to take that feedrate. Added a G0 z3. after my last X move and worked fine. I have been running that program with a few changes to the z heights and x travels just to do some quick facemilling for over a year and now today it decides to be moody. Thanks again.
