I wrote in January that I was having problems with ruler quilting on the tumbling blocks mini.
At that time the problem was pressor foot pressure — try as I might, I was unable to get the pressor foot to lift enough to allow the quilt sandwich to move. I was using MonoPoly in the needle and Invisafil in the bobbin and it’s possible that tension issues might have contributed (although I had used those same threads with the walking foot quilting and had no problem at all).
Today I was quilting En Bourgogne and decided to try some ruler work on the B blocks. This time I am using Gütermann polyester in both needle and bobbin. I made a test run at the edge of the batting and the foot moved easily — I didn’t take a photo, unfortunately, and I pulled out the thread before starting on the quilt itself. Confident that the previous problem had resolved, I made a start on one of the blocks in the middle of the quilt. The result was … not good.

Apart from the issue of moving the quilt while keeping the ruler still (which caused uneven stitching) and the extreme difficulty in getting the foot over seam allowances, the tension was way off — the bobbin thread was being pulled right through to the top. And yes, I double-checked that the pressor foot was down while I was quilting (it’s not easy to tell with the ruler foot). I’m pretty sure that I’m using the correct option within the ruler work menu — it’s a thin cotton batting with not much puffiness, as you can see from the walking foot lines I quilted earlier.
Has anyone had similar issues with the Janome 9400 or 9450?
I’d take it back to the shop where I had the upgrade installed, but they’ve moved since January and, while the technicians are the same, all the front staff have changed and I’m not confident that there is anyone there who has actually used this machine.
