Domino 500 - Scraping/rubbing

[TD5]

Domino  500  new, after  30-50 dominoes  the  carcasse  under the  cutter has  signs of  movement/rubbing  on the
plate. Is it normal that oscillating part is touching the base ?
Must I trim something ? there  is some secret about this problem?
Thanks to all for support and help.

Using DC?

I checked mine and there's no markings like that.

I just checked mine as well........No marks either!!!!

The thin Stainless Steel plate is very close to the oscillating mechanism on my Domino, so perhaps yours has had a slight knock on the plate, pushing it up slightly and therefore rubbing on the moving arm....??????!!!!! Check the plate is still perfectly flat, just to make sure.

Check with Festool Service. I doubt that is normal as I don't see that kind of wear on mine.

The marks are too coarse to be metal-on-metal. So you simply had debris between the cutter sweep and the base. As was mentioned above, make sure to use a vac with the Domino.

That said, even for debris, those marks are pretty coarse (far apart). That means the debris was fairly large in size. Make sure you are not plunging too fast. Also, inspect the tip of your bit to make sure it hasn't broken off. It is not totally uncommon for a new user to break the tip of the bit due to plunging too fast. Many new users that are accustomed to using a biscuit joiner will operate the Domino as though it too was a biscuit joiner. It is not, and it takes a little bit of retraining to change habits from biscuit to tenon.

I think that if you hear the bit screeching, you're plunging too fast. It's an oscillating router bit and it should sound like any other router bit.

You don't want to dwell because the bit gets too hot rubbing against the sides of the mortise the bit's making and excessive heat can cause failure. You don't want to plunge too fast, (screeching sound), or you're taxing the bit and it could fail. If you have an overheated bit that gets plunged too fast, well...

I've been guilty of both but have tried to get Zen with both the 500 & 700. I think I've got it. It's different for every material and every piece but it's a "feel thing".

I've done a lot of demo's with both machines with a lot of people and some people are Naturals and have it perfectly, first plunge. Others need a little practice.

Another thing that I think comes into play is fatigue. I know when I get tired and have a lot left to do, I tend to push the limits to eliminate time in the aggregate. It can cause problems.

Trying to shave a little time off every plunge is not the best way to save time overall. Let the plunge be the plunge. Trying to save time in the 'set up and process' works better, in my opinion.

I use always CTL and Oneida cyclone with all Festool machines.
So no debries, marks on the base are the same of the body: one is oscillating "against" the other.
Sure.
Probably first dominoes were too fast  but now it's clear to listen to the sound and adapt the force.
No bit is damaged, all mortices are perfect! 
One day or another I'll send the 500 to Festool repair center for a check.
Thanks to all for replies.

I had what looks like a similar problem with scratches and also running very hot (http://festoolownersgroup.com/festool-tool-problems/domino-running-hot/msg252419/#msg252419 - scroll down post)

I sent mine back to Festool. They polished the aluminium die casting part of the spindle and that seemed to cure the problem. Quite high tolerances so I guess a few units are a fraction off.
