Hosting a quick topic on New Year's Eve anyway.Since yesterday the owner of a Flashforge Adventure 4.From the box a piece of cake to get this printer working. The first two prints have already been made, the well-known Benchy and an XYZ cube. Quality is fine.But I can't get the residual PLA off the heated bed.I can only get the printed object off with considerable force (hammer).The temperature for the bed is 55 degrees and that of the nozzle 220.I am now stuck with a bed with remnants of PLA that will not come off. Who helps ?Happy New Year everyone :-)Sincerely,Guus
