Why this error?

Hi folks,

I'm puzzled, the following file has a line of gcode that I have used before without any problem.
The last two files I have tried to loaded into LCNC generated this message:

" Line 15 Cannot use axis value without a gcode that uses them".

I have used this before with no problem, what have I done wrong and how can I correct it?

OS= Hardy Hero
Release= 2.5.2

Thanks

Hi

It is on line 14, so near line 15 not on it!

G80 is part of Modal Group 1, so using it cancels other model commands in the group.

Because all the motion commands are in this group, you need to set either G0, G1, G2 or G3 after calling G80
to start movement again

regards

Got it!

Thanks

Something just occurred to me.

I thought G80 canceled canned cycles, NOT motion commands.

Have I missed something here?

You can prove it to yourself by putting G1 in front of the line, the code works again.

"Modal commands are arranged in sets called modal groups, and only one member of a modal group may be in force at any given time. In general, a modal group contains commands for which it is logically impossible for two members to be in effect at the same time - like measure in inches vs. measure in millimeters. A machining center may be in many modes at the same time, with one mode from each modal group being in effect. "
