I was working most of the weekend with my TinyG. Sometimes fristrating, often a lot of fun. Until my TinyG stopped talking to me.
I was getting ready to rehome after my spindle hit a hold down. First I moved the spindle to Y=0, and it did that. But when I issued x=0, nothing happened. Then I noticed that TinyG stopped talking on CoolTerm.
I power cycled the 24V supply for the TinyG. I restarted my laptop. My card is in a metal case, with a big fan on it. Nothing has moved or changed about my power supply or electronics.
The PWM red LED is on solid, and so is the blue power LED. The RX light blinks when I hit return, sometimes he TX. No response on CoolTerm.
How do I reset the board? How do I test to figure out the problem?
Sounds like yolu have done most of the right things. Most likely the USB connection between the board and the host is at fault. You can try the following steps - in roughly this order. Once we found a bad USB cable. Wasted quite a few minutes on that one. Are you on Mac, PC or Linux?
- Power cycle the TinyG board. Let the power LED stay off for a few seconds before turning it back on
- Physically disconnect the USB and replug
- Disconnect coolterm session, rescan ports, and reconnect
- Kill coolterm terminal and generate a new one. Saved settings is helpful.
- Kill coolterm and restart
- Reboot your host.
It sounded crazy, because I did I did everything you said except for disconnecting the cable. But I followed your instructions. After reconnecting the USB cord, everything worked correctly.
No idea what could go wrong with the cable between issuing a Y command and issuing a X command. But everything is working again.
Thanks for your help, Alden.
