I'm not sure I follow. If you have the SS externally powered and turn off the external power supply it will of course shut off and the PC won't see it any more. If you have the SS powered by the USB cable it should always show up.
I have *not* tried several things (had a job to run today) -- USB cable is unchanged, computer is unchanged, etc. Much to try before I truely throw my hands up.....
Oh -- I checked, this is a recently shipped SS board that have the cap and the resistor next to the USB port on the SS removed.
Hanging it up for today.
Q: When the plugin is scanning for the SS USB device, what exactly is is looking for? The device had many enumerated properties, one of which is not getting picked up... sometimes. The device is clearly being recognized by Win7, as evidenced by it showing up in dev mgr when plugged in and then going away when unplugged or powered down.
Based on the error messages it is pretty clear it's related to the USB comms. Once the FPGA gets initialized, it's all good until usb comms drops.
Time for dinner. Managed to get cut job done, though it took 5 tries to run roughly 12,000 lines of gcode. Should have taken, with tool changes, 90 minutes, worked on it 5 hours.
