Hello everyone

I have a quick question about the need of a "EMI" filter with a Tiger Saw Mod.

A friend of mine just purchased a nice looking TOM, with an installed (but non working) Tiger Saw Mod. The motor's plus side is wired directly to 12V on the power driver board, and the motors minus side is wired to J126-3. As far as i can read this is normal when using 1.4H with a new security chip. A new 1.4H ROM was supplied with the machine (but not installed), and the seller told him he just needed a new security chip to make it work.

But i read a couple of places that connecting the motor through a EMI filer is strongly recommended?

So my question is, if any of you are running the motor without a filter? And have any of you actually had bad results when NOT using a filter?

Not that i think it matters, but i am going to make him a U6 with the SOREN modded 1.3X ROM. This ROM has the Tiger Saw mod ported from 1.4H and on top of that it has some other improvements. And using this 1.3X (modded) it should work just fine with his existing security chip.

I added a post, and only had 2 jams since, in a couple of years. Before that I had them quite frequently.

But I would definitely still recommend Sorens ROM, as it have a couple of really nice features. Especially if you want to add an easy DIY Tiger Saw mod.

That looks awesome!! Really nice quality and craftsmanship

I would make a new mod, using a simple 12V computer fan motor, and hook it up to the powerboard. Then install Sorens latest 1.3 custom ROM with support for a tiger saw mod. Works even better, and doesn't require any extra switches or anything. It really is quite easy to do these days.
