Am I alone here in thinking the pierce delay setting should belong with the tool, and not with the machine/post processor? You have to create a new machine and load it for a different pierce delay setting, or just edit the code for each effected part. I prefer it was under the tools Cutter tab in the tool library. Granted, I imagine if you’re cutting just one type of metal in a narrow thickness range, it really doesn’t matter that much.
if you use sheetcam, the pierce delay is in the toolset. I believe the only option you have in fusion is right before you post process.
Bit late to the party but in Fusion360 this can be in only the POST, MACHINE or OPERATION or a combination of them (rules do apply)
if you wanted more than a global control over it, then it would go in the OPERATION and would be settable per-operation.
