You know how passionate I am for free motion quilting with rulers. So when I heard that Janome Canada did not recommend the ruler foot be used on the Janome S7, MC12000, and MC15000 I wanted to figure out why. I'm pretty sure I have sold the Janome ruler foot combination to owners of these machines and haven't had anyone come back with problems, so what was going on?
Since I work in a Janome dealership, I had access to the S7 and shot a video with my new iPad mini. The mini made editing my video a lot easier than I have been doing it before, so hopefully I will do more videos as soon as I get a camera mount for it.
Watch the video first, but the main issue is the ease of which the presser foot can be raised because these machines have an automatic/electronic presser foot lifter system. It's still an aspect of the lack of clearance between the top of the thick edge of the ruler foot and the bottom of the needle clamp. As always, with any ruler foot, make sure the foot is down when the needle is down and conversely, don't raise the foot when the needle is down.
With this electric lift, it's very easy to accidentally fail to follow this cardinal rule of ruler foot use. Janome Canada says they will not cover any damage to these machines (S7, 12000, and 15000) if you use the ruler foot on it. (I haven't heard anything from Janome America.) I believe the damage would be that of throwing the machine out of time, but I am not entirely certain. This isn't a huge issue to fix, but we don't want to take the machine to the shop.
I think it's doable to use the ruler foot with these machines but that's a risk you've got to decide to take for yourself. I wouldn't want you to do anything to needlessly risk your machine.
My ruler work blog linky party is still open and we've had some incredible work shared through it, so go visit the participants and if you've got a post to share on ruler work, now's the time to do it!
