Hi. First Post, first question I'v been reading all posts about warping. But cannot find a solution. THe problem is only in the Layer that touches the Hot Bed. The rest of the print is perfet. Tryed with Low bed temp, brim, using a heater arround the printer, but always the borders warps and the first layer seem to be "melted". Setting. Printer Prusa I3-x No vents. Hot Bed to 50º (tried till 95º) Filament temp 240º Printed directly to Hot Bed (METAL, not glass) Using Hair Spray to fix it to bed. Speed 50mm/s Layers at 0.1mm Any Idea? Regards
