I play on a server and I build a lot so I use schematica and i use frorge 1.11 version. The server allows the printer but always when i build with the printer some of the blocks i place disappear! This is very annoying... how can i fix it?

Try to increase the placement delay. This is usually caused by "high" ping to the server, the higher the ping the worse it gets. I haven't found a solution for this yet, sadly.
