[How to disable the thread break sensor?]

I'm going to lose my mind if I can't turn this thing off. It used to work but now using a micro thread and it doesn't like it.

Thank you Jim.  Clean with alcohol, I assume? 
I had edited that post but it didn't complete. Can you also tell me how to fix my thread sensor adjustment. It has started beeping allot and I've tried various amounts of wrapping around the wheel. That, coupled with the intermittent beep that I've never actually figured out - it is all annoying.

The laser light on the panto side flickers and is very easily turned off. I gently tap and rotate the cable to get it to come back on. Usually stays on while running the machine, but now I'm having trouble with that. Has the light failed and I should replace it? Thanks in advance,

[Stitch problems on top]

Thank you, Cagey! I didn't get notified of your reply. I think you're right about gradual increase in needle. I get panicky. Also I have slowed way down, loosened needle thread tension and lengthened the stitch. It's going much better. I have a second quilt to do for thIs lady; I'm going to try a different thread than the Innovatech (first time use for me). I also prewashed her wide back hoping it would improve the 'hand' of the fabric. I'm nursing the machine thru these two quilts; it worked beautifully the day before I started this one. Hoping it is bad thread and bad fabric. Because most off my troubled is moving right to left, I fear I need to replace the encoder wheel. How hard is that?

[Stitch problems on top]

I put in a 5,0 needle and turned it about 2 minutes to the right of center because that's worked for me before. The top and backing fabrics are cheap Joann's. Everytime I have stitch quality issues it is cheap or stabilized knit fabrics. I wish I could find a tutorial to help me understand what is happening. A $20000 set up shouldn't be so finicky about fabric quality? Should it?

[Stitch problems on top]

I am having problems with random skipped stitches, loose stitches and thread breakage on top. Needle is new 3.5. thread on top is Innovatech, bobbin is Deco Bob. Ideas?

[Needle noise in one direction]

After winding new bobbin I began having trouble. Needle breaks, needle thread fraying, bobbin thread breaks; threads are so fine 50 in needle and bottom line in bobbin. After tweaking tension it is sewing better but is making a popping or hitting sound when I pull the machine towards me. I've quit for the night and am worried it's going to break another needle. It is better if I slow down, but is dense quilting I'm doing. Also, I am in manual mode. I have an appointment for maintenance next week but hate to not work for six days.... Any ideas? I know I should do my own maintenance but who has time to learn another thing? I be too busy learning creative stuff! TIA!
