Hello all,
I have a question about recalling alignments and proper practices regarding that. I have encountered problems when recalling alignments where it appears that the 6 DOF's are not locked in or something is going wrong with the alignments. I will post some general code to show what i mean by this.
When programming certain parts, they call out theoretical offsets where I offset from my abc alignment like shown in the code. What I usually do (not shown above) is re-establish the ABC alignment completely then at the end add my offset. I've always wondered if I was doing too much work wasting time level, rotate, translate every single alignment or if the above code is fine where I recall A1 then just offset.
