spooken to soon

I printed 3 medium sized object ok all together with around 300 x 100 mm. got a great print.

Just to check printed a small calibration 20x20 and all ok

tried to print a larger one 350x350mm and the x axis seams to block.

Teste with g1 x400 y400, after homing, and i the x axis always seams to block around 2/3 of the way.

i have testet with f parameter from 6000 to 1000, and always the same result.

I think that it needs more power source using this:

Can i use 2 diferent transformers, or must o change to a stronger power source?

Note: mi heated bed is powered with 220v with a SSR conetect do the board, and tests were made with extruder and bed off
