Had my Iconic 6 for about a year and getting into some larger projects for my daughter's classroom (she's a second-grade teacher).
About to start a sign that will take 26 hours to carve. I've looked but haven't been able to find any recommendations on how long a project should run before setting a break point. Any suggestions?
If anyone knows otherwise, please correct me, but Axiom only seems to specify that the machines are designed with extra-long duty cycles in mind and I can't find any limitations. I have an AR8 and the spindle is water cooled; if the iconic is water cooled as well, it's probably fine to let it cut in a single run as long as you feel it's safe.
I have another machine where one of the bearings on the Z-axis failed and the spindle plunged into the workpiece (plywood in this case) during a semi-attended job. The friction from the collet against the wood caused a friction fire. I was in the air-conditioned part of my facility and just happened to walk back in to check on it. Saw the flames shooting into the dust collection system and the smoke billowing everywhere.
The fire died down as soon as I shut everything down and reduced the airflow, but it smelled like smoke for weeks and the collet nut nearly friction welded itself to the spindle.
Accidents can and do happen, so just make sure the machine is isolated enough to not cause a problem if a catastrophic failure occurs, or make sure you're watching the job in shifts.

I have the iconic 8 and I stop it and save my progress anytime I step away for more than a minute. This is for reasons already mentioned but also because I still don’t trust the unit. It has no error or fail detection and I’ve ruined a few projects on optimistic trust. I’ve learned to use an air compressor and blast air into the rear vents of the spindle housing and it’s the only thing that has prevented sudden stalls of the spindle. (Still waiting on that fix, Axiom). It’s easy to restart your project after any number of pauses.
