Help Domino xl 700 slowing down.

[mino]

What I would do is take it to a dealer I bought it at, along with a piece of wood with me to do a "live" test.

Since you have the tool only shortly, it can be a technique issue or anything in between. Also, it may help calling Festool and asking for an EXPLANATION of what may be causing the slow-down as per the video and/or whether that can be "as expected" under some
(which ?) circumstances.

Also, no one is infallible. Including the Festool service technicians.

You can have encountered a fault/issue/limitation which is simply not "seeable" by the standard checklist Festool service does. No matter how extensive their checks are, they can never catch everything. We already saw this happen with the pins "moving" in the Carvex, making the blade wobbly - the standard battery of checks Service does on a Carvex simply did not check for that type of a probem => hence could not "see" the issue. Your can easily be similar, or even unique to your specific tool.

Either way, do not give up until you understand and/or resolve the issue. It is no Elder Wand, with its own psyche ..

EDIT:
Looking at the video this seems like a speed sensor issue: The tool notices the speed dropped too late (i.e. when it already dropped too much) and thus adds power too late.

I have a Festool DR20 drill and it behaves the same when used at (too) low a speed - the feedback loop from the speed sensor in it is just too slow and does not react fast-enough to maintain consistent speed. For the drill this is normal, as it is not designed to operate at such a low speed (think 100 rpm). For the Domino it would indicate the speed sensor is "noticing" only when the speed falls too much and then needs to overcompensate. I do not have an XL so not sure what sensor is used. But this can be as simple as some chip stuck at the wrong place giving a Hall sensor false readings. IMO this does not look like a "power" electronics issue as it clearly has enough power to recover the speed once it "decides" to do so.

Last point, I do not believe Festool service would be trying the tool on a piece of wood/under prolonged load -> their default checks would thus be very much expected to miss this type of a problem and not every technician would (necessarily) understand how to troubleshoot this, even with a video attached.

Best you give Festool USA a call, instead of a "written" discussion in tickets where it is all so easy to lose track of what is actually being communicated.

If you ask me, the onus should be on Festool to record a video of the machine's running when it was at its place for fix for the second time, and show it to you that nothing was wrong. In fact, I think that should be the STANDARD procedure in cases like this. No good customers would send their machine in TWICE for service if it is working properly. (My brother's luxury car dealership sends him a short clip showing their technicians working on his car everytime his car is in for an oil change, etc. -- miminal work, added customer satisfaction (or reassurance)).

Well, a DOMINO even in the XL variety, costs about as much as a regular service check for luxury car ... and has about 100x less profit per sale/customer to fund such extravaganza. However nice it would be.

The way these "serialized/optimised" service processes work is they depend on the customer to "raise hand" and raise a (specific) concern ideally via call-in and/or ideally an email *followed* by a call-in.

This is not to say stuff cannot be improved - it always can - but we often forget Festool is no Apple as far as their profit-per-sale goes. Not by far. Most their prices go to salaries and R&D. Treating every customer service request like a Mercedes dealership does would force the tools costing 10+ % more atop what they already cost. Sadly.

You clearly missed the point.

It's about using the simple (cell phone video) technology that's already there to keep customers engaged and happy. The customer advisors (all car dealership here -- luxury cars or not -- have them) take a 10 second clip, and text their customers. That kind of cost is not even a recognizable fraction the car dealerships assign for TV, newspapers and marketing.

Of course, marketing and keeping customers loyal is a complex subject in this changing world.

I sure did.

Over here we have one car service center which offers to record the whole service session. The technician would setup cameras as applicable, a clerk then does a short edit (making sure no confidential/private data in it). Last I heard they charge about $200 for that service - on demand. When reading your post that is what I had in my head ...
