Re: [CAD_CAM_EDM_DRO] Newbie - Help & Clarifications

I have to agree with Dave here. You risk damage to both the machine
and yourself by disabling or removing these switches. the risks
involve more than human error. But like the poster below I've seen my
share of people permanently injured because they thought that a human
error was beyond them.

Thanks
Dave
