Hi Tom, Did you see my message about the same issue I had with my platter burning out a section?

I resulted in cutting a picture frame glass of 3mm thickness and put that on the platter, it works very very well. It also makes the platter flatter and easy to clean. I've ordered a spare traditional magnetic cover and will see how that works later.

Also I've played around with the slicer settings and that has made a tremendous difference to the quality output. Let me know how your getting on.
Regards
Steven
