Purchased an old Larken CNC in May, running Mach3 on XP.
When I booted up the computer today, all Mach 3 configuration settings were gone. All input and output signals disabled, pins and ports set to 0. Smooth stepper IP set to 0-0-0-0. Home and soft limits disabled and set to 100/-100. Any way to recover the lost settings? Would a system restore do it?
