Hi John LaBaff,
Please check and confirm the Safe Z and Home Z values specified in your calculated toolpaths within Carveco Maker.
Thanks for your time and consideration.
Safe Z 1.32093
Home Z 1.9011
Hi John LaBaff,
Your specified Safe Z and Home Z values are almost certainly too high. Please edit the Safe Z and Home Z values in your calculated toolpaths to 0.2 inches, then re-calculate and re-save your toolpaths.
After doing so, please load your new toolpath output files into your machine controller software and test under safe conditions (dry run, air cut).
Thanks again for your time and consideration.
Hi John,
I am an SO3 owner and this issue of Z axis crashing is known about but not resolved. There appears to be a software conflict between Z axis position and BitSetter determined Z height values, which you have to use when using Carbide Motion, especially if you want to initiate a tool change in the middle of a job.
You can try to contact support Carbide 3D. I have done with out resolution. I have seen this many times referred to on the Carbide forum as a user error. A friend of mine could not make his own 3xxl work and after 13 months of trying, he eventually got his money back by opening court proceedings.
I have experienced BitSetter related Z height issues with air cutting and inappropriately long tool measurement cycles. My latest was an unscheduled catastrophic crash of the Z height after successfully cutting two blocks of wood. Carbide 3D no longer respond to my support enquiries. This is the reason I am using Carveco and will hopefully move to CNCjs or similar soon.
At the minute, I am looking at changing the 8bit controller supplied by Carbide 3D for a Duet 3 controller. The image shows the workpiece I had ruined as soon as I had finished the initialisation routine and tool measurement on my SO3. It happened at very high speed and could be considered to be a dangerous unplanned and unspecified or programmed event.
The imaged plunge and cut occurred in about 1 second. The wood was beech and I was using a 2 flute 1/4" Amana carbide cutter at 20,000 RPM. The cutter just caught the edge of one of my modular vices and without an emergency stop, I would have seen the cutter plunge through my SMW fixture tooling plate as well. Good luck with Carbide 3D.
