M563 P0 S"T0" D0 H1 F1

[jay_s_uk]

@sgk what problems are you having?

[A Former User]

@jay_s_uk when I print my pieces where the cubes are of a really bad quality even with my cr10 which is not in good condition I have better impression. I have changed a lot of things on my blv and always a shit quality excused me word

[jay_s_uk]

it’s the same if it’s not worse

Looks like you need to to flow and temperature calibration. Here is a website which may help you with that https://teachingtechyt.github.io/calibration.html

@oliof
I have done plenty of times

[oliof]

@sgk you have massive deformation at the bottom of the cube which looks like the heated bed is way too hot, and the extrusion looks very uneven but not spotty/spidery, except for the stringing. Maybe share the gcode file with us (you can upload it) so we can take a look.

@oliof
the deformation is the fan

@sgk what material is it that you are printing?

Looking at your gcode file you have set the bed to 90C. That is waaaaay too hot for PLA and I doubt your extruder temp of 195C would be correct if it was PETG or ABS.

Leads me to think that @oliof was right and the deformation at the bottom of the part is because it is too hot and the part is melting!

TYPE:Custom
M104 S195; set extruder temp
M140 S90 ; set bed temp
M109 S195 ; wait for extruder temp
M190 S90 ; wait for bed temp

but if I have but not 90 it does not adhere to the bed.

@engikeneer
and as we see in the photo it is already peeling off on the corner

@engikeneer I've been fighting for months, I've changed a lot of things but still the same I'm at the end of the line

[oliof]

@sgk what is your print surface?
