Troubleshooting (Haas ST-15Y)
Program/CAM Problems
When I start drilling a hole the live tooling motor turns on and the main spindle doesn't turn.
You have the "Live Tool" checkbox selected in the Post Processor tab of the tool you are trying to drill with. Uncheck this box to use the main spindle to drill with. Usually this happens if you are copying a drill bit from the mill tool library to use it on the lathe.
Drilling with one of the live tool spindles is usually a waste of time because the main spindle is much more powerful. Only use the live tool spindle if you need to drill off-axis.
