I bought this used Summa F1612 back in 2021 , but I've been experiencing an error with it lately. Despite reaching out to several technicians, they're all suggesting that I buy a new machine. They've quoted me a price of 12k for a brushless system replacement. The issue is that the machine will shut down unexpectedly in the middle of a job, showing a fatal error related to the X-Motor or Encoder. Unfortunately, it won't recover from this error on its own. I could really use some help with this problem. Any assistance you can provide would be greatly appreciated.
