Issues with BitZero & subterranean bit plunge

[RichM (Rich Morris)]

Hi Walt - coincidentally…

Z Zero merely a suggestion on occasion

Not sure what happened, but CM chose to ignore what I set as Z Zero. This was run #3 of the same project, where the previous 2 cut as expected, but after resetting zero for X/Y and Z then starting the job the first cut plunged beyond the limit of the end mill and ruined the board segment. Afterwards I did a rapid to X/Y zero, which was correct, then still annoyed and petulant in the moment had the machine rapid to ‘where it thought’ Z zero was (+6mm), plunging again it snapped the already ruin…

Since your issue is predictively repeatable, you may want to contact Support and walk them through your process so they can recreate on their end and hopefully provide info and/or a long-term solution.
