Have you tried a new (or different) USB cable?
Yes. 3 cables that have worked on this machine before.
Have you tried starting up with only tinyG connected, no other connections (to motors, pwm spindles, etc)? Could be a noise source is corrupting tinyG ground, which becomes PC/laptop ground when USB cable inserted
Perhaps your Vmot PS has gone bad? tinyG will run with simple 12 – 30 V supply, e.g. a spare laptop or router supply that you ‘trust’.
I really wanted this to be it. Ive disconnected everything from the TinyG, tested my power supply, and put a new clean wire between the TG and PS, and I am getting the same result.
If the bootloader is ok, then I should be able to hit it with new firmware within 3 sec of startup right? Windows alerts me that the USB is not recognized a second or two after the bootloader process is done, so there might be a chance of flashing it that way. Not sure how I will know what port it is on?
