I think that it might be a heat problem, it had been really hot here for the past few days and I have been running my machines a lot. I have two of the same machines and one started having this problem a few days again, just today my second machine is having the same problem... you think it could be caused by the heat? I will switch out the motor for a new one to see if the heat just killed the motor, I hope it didn't affect my driver. But I need to get things up and running fast I run a small business off of these machines and I need them up and running! If anyone has suggestions for me to try please let me know!
