Actually I never had this problem. Apparently strange if I read all these comments. Of course sometimes there is a warped blank, but it flattens perfectly when I put it on the warm cuttingtable. I use 2mm blanks, heating with the two Souri lamps and between 40-50 degrees C. I didn't have those kind...

I purchased a propagation heat mat , which is flat and heats to around 30c. Put a stack of discs on top of each other, eg: 20 disc pile.
