Hi Mike
Yes getting a bit better.
I found out why the platform was not tracking after 10-12 minutes. There is a material taped to the motor side of the metal plate - assists resistance. The plastic type tape had a bubble in it - so it stalled at that part of the cycle. Sent Brian some pics of it last night and he suggested that I unscrew - retape it down and should be okay. He will be sending a replacement tape. Excellent service.
He wants to give me a call to discuss.
Cheers Petra
