Had the opportunity to test the new ddf40, and was eager to finally do quick and accurate shelve pin rows... but what a disappointment it was when I did this with a low kitchen cabinet. The rows are misaligned by a millimeter or more! I used insert “k” for the 32 mm spacing. After finding out rows were misaligned, I measured the K pin, which is 4mm in diameter. Why didn’t Mafell make this 5 mm??? The current size allows for jiggle and therefore misalignment. I am so disappointed. The machine is very well machined with clever feautures such as two depth stops. Was hoping to replace my domino and Lamello classic for this red monster, also for being able to use dowel connectors such as these : www.knapp-verbinder.com/en/produkt/quick-set-2-parts-dowel-connector/. Niw I am Not so sure anymore. Does anyone know a work around for the k insert- other than buying the expensive guide rails? Also does anyone have experience with the Knapp connectors or other non glue dowel systems? Would love to hear. Thnx

I don't have the DDF, but have seen it used at a Mafell demo. I think the idea of the 4mm pin is so it doesn't damage melamine finish pulling in and out of the hole. If you pull the DDF in the direction you are working down the board, it should give you 32mm - (i.e., if you are working left to right, you need to insert then pin then pull the DDF to the right) - if you do not do this you will get 31mm. It's done by design - it would get pretty tiring fast trying to line up a 5mm pin in a 5mm hole and then removing it without causing damage.
I have connectors similar to hose you link to, not sure if they're the same brand or not. A pair of 8mm holes is all you need, works very well.
Persevere with the DDF - you'll fine once you get the hang of it.

Thanks for your reply. What you describe is actually precisely what I have done after I first noticed the wiggle in the pin. I own the first gen domino and it has the same spring loaded pins as the Mafell, so I am Used to referencing of an initial slot/ hole by inserting the pin and pulling along the working direction. Still could not get it perfect building the second cabinet. This was a row of 640 mm , not too much I would say. Maybe it’s me, I sure hope so. The plastic inserts seem not of the best quality though and I would love a more durable solution.

This is why I don't bother with the plastic add ons. The rails are expensive but super accurate.

I've been using the 'K' shelf pin attachment for quite a few kitchen cabinets now and I haven't had an issue with shelves being out of allignment with each other and all the concealed cabinet hinges have gone in no problem. As aas mentioned i'm just always careful to push the DDF40 to one edge as I work and make sure that the direction is repeated on the opposite piece. Saying that, IF Mafell were to release a metal version of the 'K' pin I would purchase it in a heartbeat.
