Welcome to the forum, Anna, thanks for joining us.
Sorry to hear you are having failures but, be assured, you are not alone (for example, if you read through the forum, you will find that there are numerous stories of coleslaw 'soup'
)! Just about everyone has failures at some point and we all learn from them and share on the forum offering and giving thoughts, suggestions and advice.
I have the older model so cannot comment on chip times, but I have found, for instance, when chopping onions and garlic I turn to speed 5 then drop the onion and garlic through the lid and that seems to give a better finished result for me. As Judy says, when you get a chance, browse through all the recipes on here and you will pick up loads of ideas. Also, don't forget, many of us on here have had our machines for many years now and we have practical experience of just any problems you may encounter. Just ask us and you should get feed back fairly quickly.
