A user has reported a possible problem with the textured plate as follows - during the initial process of cleaning the nozzle, just prior to the commencement of bed leveling, the nozzle scratches directly on the plate (at one end), in order to be cleaned thoroughly, so that the bed leveling is performed correctly and assembling correct figures. The textured plate also has PEI surface at this area where the scratching takes place (see picture), whilst the cool plate does have bare metal area there. When the nozzle scratches on the PEI, it did happen that some of the material got into the nozzle and created a small clog. My picture show my textured sheet after having been used for while. You can see the area that has been scratched blank. Just be aware. I am not suggesting any solution. This is up to BL.

It’s almost like they have the cool plate or engineering plate selected instead of the textured pei. Mine doesn’t do that on the textured.
It should be doing this scratching on the plate just prior to commencement of bed leveling. If you opt to not use leveling, it might neglect this step. It is part of the start code - see here
G0 X128 Y261 Z-1.5 F20000 ; move to exposed steel surface and stop the nozzle
M104 S140 ; set temp down to heatbed acceptable
M106 S255 ; turn on fan (G28 has turn off fan)
and so on
