Hello all,
I have faced strange issue with Haas mill. The problem was spindle orientation while tool change having umbrella type ATC. The drive lugs supposed to parallel with X-axis while it goes for tool change, but sometimes in a while the drive lugs are little bit off (approx. 10 deg. angle from X Axis Viewing from top). The part was using five tools until final finish, and this issue was happening in a same tool (3/8 Tap). Even though the program has M19 for spindle orientation, but the processor was ignoring it sometimes. We did some changes in program END and it worked.
-The Program we were using before

-After changes

M19;

Is anybody has idea about why it ignoring M19 before and why not after.
