I'm trying to run the following code:
T2 M06
G90
S436 M03
M08
G01 G43 X1.75 Y-.45 H02 Z.1 F200.
G83 X1.75 Y-.45 Z-1.8814 R.1 Q.125 F2.15
G80
M09
The spindle rapids to Z.1" (above the part) and starts drilling. When it reaches Z-.025", it stops moving. The spindle continues to turn, but the axis no longer moves.
I've run code like this hundreds of times before without any problems. And my MiniMill runs the same code just fine.
To get around it, I had to modify the code so that the block before the canned cycle uses G00 instead of G01.
T2 M06
G90
S436 M03
M08
G00 G43 X1.75 Y-.45 H02 Z.1
G83 X1.75 Y-.45 Z-1.8814 R.1 Q.125 F2.15
G80
M09
Does anyone have any idea why this would happen?
