Hi,
I have a FLSUN V400 delta printer (30cm round plate) and I’m going crazy trying to find a solution to a bed_mesh problem, so now I’m asking for help.
The V400 has a bed_mesh probe.
The problem is that always in the same area of the first calibration point (the first that the probe touches on the plate X0 ; Y= -148) when I print the nozzle always remains too raised (I think about 2 tenths) and so obviously the first layer it doesn’t stick.
I obviously rotated the print plate but the error always remains in the area of those coordinates.
Anyone have any ideas on how to fix it?
Thanks for your help.

The only way to fix is to reduce the speed of the first layer at 40 mm/s instead of 60 mm/s like defoult of Cura setting for FLSUN V400.
