I have the Festool Dominio DF700 but sometimes need to join 18-20mm wood, I wanted to get the Seneca plate and use a smaller cutter, but I am not sure if it would be best for me to get a biscuit jointer instead maybe Makita or DeWalt, as the Seneca plate is quite expensive I have found this thread WARNING ABOUT USING SENECA ADAPTER WITH XL700 DOMINO, but it is 5-6 years old and was wondering if things have changed regarding the Festool warranty and gearbox problems, has anyone on here used the Seneca plate and small cutter with the Festool DF700
