fat letters HELP

[horsestitches]

I have 2 of the exact same machines doing the exact same designs and as far as I know all of the settings are exactly the same...but one is sewing the totally different.
The last design I had loaded was just lettering and the lettering came out about 3times wider than it was supposed to be and all jaggedy. I thought maybe the hoop wasn't on there securely and changed hoops, tightened the arms and clips...no better. Greased and oiled the machine..nothing. Checked bobbin tension and material thickness..nothing.
I have absolutely no idea what to do now and not sure how to find a tech.

My machines have done this to me once as well. Very frustrating!!! It turned out that I needed a tech. The problem was the cables that run underneath the grey covers at the top of the machine. The tension was off on the cable which allowed the machine to make bigger movements. This resulted in wider columns on this one machine, so lettering looked aweful. Can't tell you for sure this is it, but it's something to look at. Good luck!!

Thank you very much, now I just need to find a tech.
