ender 3 pro dual Z

[dreamy elbow]

hello

out of nowhere after installing dual z my printer just started printing into the bed

the nozzle scratched the bed big time

anyone know why

its a splitter cable setup

I used wd 40 specialist silicone lobe as hirnspiel told me its good

lube*

[spark egret]

did you level it again?

[dreamy elbow]

i got bltouch

with a offset that should not be drilling into the bed

[trail swift]

Run the offset wizard

Did ypu square the gantry?

[dreamy elbow]

like use two objects to "level" it

or

[trail swift]

Yes

Both sides of the gantry

[dreamy elbow]

yeah

[trail swift]

At the same distance om the frame

[dreamy elbow]

i used these two random bottles the same size

idk I'm skeptical about this upgrade

[trail swift]

Did you run the offset wizard?

[dreamy elbow]

no

is the silicone specialist wd 40 good as lube

the gantry is very hard to push up or down

[trail swift]

Yeah thats normal

You know have 2 motors to push

[dreamy elbow]

the printer is making a very loud sound when I put all 4 legs on the table

well the sound is the same

as the normal idle printer sound

but its like 2x louder

[trail swift]

Yeah that happens with the dual z

[dreamy elbow]

do I need to change some firmware stuff before printing?

[trail swift]

Not necesary only if the motors have a hard time to move

But since you took apart the gantry

You have to change the z offset

[dreamy elbow]

why though

also with heated bed?

or not

[trail swift]

Nop

[trail swift]

Something i noticed when doing changes on the gantry

The offset changes

[dreamy elbow]

ok yeah the offset is different by a whole millimeter

wtff so weird lol

its fine since I needed to tune that bitch anyway

starting up a test print

bruh it prints normal now

funny printer

thanks for helping

check this ticket in a few hours if possible because there will probably be extra issues
