I have had my NOVA DVR since Feb w/ no problems at all. I have pretty much ran the gammit on it as well - from some small spindle work to spinning around about a 60lb slab to make a bowl from.
The other day I started turning a small bowl when all of a sudden the I was getting a fault error. It was about 11pm on Wednesday. I emailed Teknatool and went to bed. The next morning there was a response in my mailbox on a few things to try. (Which pretty much shocked me to get a response at all!) None worked so I called the woodcraft I got it from - they refurred me to the woodcraft tech number - I called them told them the info and they said someone would get back to me soon. I got a call w/in 15min from the person handling warrantee repair for Teknatool. I explained to him the problem, he gave me a few things to try w/ no success. He said that it was still under warrantee so they would send me a new head. He then asked me if I would be willing to try swapping out a new board first before having to ship out the head. I said no sure - and he fed-exed me a new board. I got it the next day by
10am - called him and he walked me thru how to swap it out. Still the same problem - he confirmed that the head was definately fried. And they would ship me out a new one on Monday.I spoke w/ the him today and confirmed the shipment was made. Should be here by Wednesday.
Its nice to deal w/ a company that stands by their product vs making you jump thru hoops.
(Not associated w/ them at all - just a happy customer).
