I read on a topic that someone plugged in a dimmer switch and then plugged their sewing machine into the switch and you can control the needle speed while you are FMQ. Well last night I bought a dimmer switch and tried to use it but my machine kept faulting out. I have a Singer Q7469 electronic that I do my FMG on and I don't want to short it out. Anyone else have the same problem or any others? Maybe I shold try it on my Singer 401.

That sounds risky to me. I don't think I'd do that.

I remember that post. In fact, I still have a note on my desk to buy one. hmmmm Maybe I'll hold off on that now.

variations in power can be damaging to your machine. i would not use the dimmer switch without checking with the machine manufacturer.

I would not do that to my computerized machine. They are built to work on a certain amt. of power. Even most of the newer light bulbs are not meant to be used on dimmer switchs.

Wouldn't that be hard on the motor?

I think that would be similar to the refrigerator issue we had when we first moved into this house.

The home inspector pointed out a couple of outlets that needed GFCI's installed. One was for the fridge. The sellers had an older top freezer fridge. Our new side-by-side w/ice & water in the door was not keeping cold enough. After several calls the repairman talked to the manufacturer to be told the computer wouldn't work with the GFCI. We had to put a dedicated outlet behind the fridge to solve the problem.

So, pretty much makes since that you wouldn't want the power fluctions on ANY kind of computerized equipment.

Now a vintage machine is a whole 'nother story - just like the seller's vintage fridge LOL

I agree, my electrically inclined brother says this MAY be fine for older machines but NOT for the computerized ones.

Oh my goodness, I would be so afraid to do that to any of my machines; it just doesn't sound right. :shock:

Isn't there a speed adjustment on your machine? Most machines have them. I put mine on half speed when doing FMQ and then put my pedal to the metal. Works great.

I would not use a dimmer or a router speed control on any machine that has any computerized functions in it.

I wouldn't hesitate to use one on a vintage all-mechanical machine - one that has no electronics/computer in it. (Your 401 is one of those)

If you have a jackrabbit machine, a router speed control is a magic piece of equipment for helping you to learn FMQ. No matter how hard you press the pedal, the machine is only going to go as fast as your pre-set speed. Cheap and easy way to get the hang of coordinating all that activity. :)
