QIDI PLUS 4 and PETG

[SPlatten]

I have a QIDI PLUS 4, set-up today and using PETG filament, I set the Nozzle temperature to 250 and the bed to 70, it started out well, but after an hour the print started to lift from the bed, what can I do to prevent this? Are the temperatures correct?

I tried glue but it takes so long before it starts printing the glue is no longer effective.

Print at the low end of the filament manufactures suggested temperature. I print Esun at 230-235 and Overture transparent at 240.. If still lifting then your initial Z offset (gap between nozzle and bed when at Z0 is too wide.
You may also want to slow your first layer down, I like to keep that no faster than 20mmS
you also need NO cooling unless you are printing tiny little items with very short layer completion times.

Thank you, I will give your suggestions a try.
