Hi guys ,
I succeed to break the plate , I wonder if I can replace it with simple glass plate I order from glazier or it is in any way special . Is it better to stick with glass or replace it with other material plate like aluminum ???

Thanks for help . I wish next printers will have sensor that stop the print in case filament is ended in middle of print ( to my knowledge in electronic it is not very big problem )

Hi
