I wasn't aware about the frame issues until I tried for a while to fix the drives. When I got the drives fixed and things still were not right is when I chased it back to the last place I would have expected...the frame. The frame is the main selling point and why I went with this machine. I don't use it for my livelihood and have limited amount not time to get on the machine...so I have had it for a while. Trouble shooting these kind of issues an hour at a time once a week when I have free time has proven almost impossible. I have spent a tiny amount of time trying to cut and the last year and a half of my free time trouble shooting.
