tinyg and cnc has been working fine for about 2 weeks. Then today started to cust some simple work. Then 5 minutes it just stops moving. Since I was using chilipeppr I thought a network issue. But with a direct connection it did it repeatly. Some times 5 minutes, others 20 minutes. Then I noticed the SPDR light next to the powerlight flashes. It locks all control of the board. Only way to reset is to power cycle. Any ideas? Bad tinyg?
