I'm completely stumped. I connect tinyg in CP but when i go to jog

I’m completely stumped. I connect tinyg in CP but when i go to jog it just flashes the tx and rx lights on the TinyG board. I have no clue why its not working. I’ve reset it, restored defaults, and even updated firmware to ensure it was up to date but I’m still getting nothing. Any ideas? Sometime when I first connect it will work for a minute and I will have movement and the motor lights lit up but then it just stops working all together. I really dont want to buy another TinyG, i havent even been able to cut a single part yet. Help please!!

Checked your power supply?

yeah, everything is hooked up right. pwr is good. im afraid the tinyg i got is a potato.

the transmit and receive lights flash when i click on a axis to jog, it just doesn’t seem to be sending to the motors cause I get no movement and the m1-m4 lights don’t light up.

is the a command i can type in to see if im actually connected to my com port? it acts as if it’s connected but i think it may be messed up somehow
