For some reason on the z it is autohoming towards the sky

lime rapids
#

suddenly or after firmware update?

#

if suddenly check if the endstop got stuck

#

@simple maple

simple maple
#

since 3 firmwares ago ive updated multiple times thinking it would fix it

lime rapids
#

hmm odd

#

do you use an endstop ?

simple maple
#

yes

lime rapids
#

check if it can move freely and if you have a spare part try that one

simple maple
#

the stop can move freely?

lime rapids
#

maybe its damaged they are often so super cheap that its horrible

simple maple
#

but why would that make the z axis go up

lime rapids
#

if your printer think its closed it always goes upwards till its gets an open signal

#

if thats never coming

#

it goes up

simple maple
#

ah ok

#

ok so i held down the z stop and it still moved down then uo

lime rapids
#

then either the z stop it self the wire or the connector is the error

simple maple
#

ok

lime rapids
#

there is also a smart chance something on the board failed but im unable to tell you what because thats extremly rare

#

you can try plugging in the cable into the x end stop and see if the problem follow

simple maple
lime rapids
#

damn it

#

have you tried plugging in the z endstop into x axis and see if that changes something?

simple maple
lime rapids
#

did you check the connection on the board?

simple maple
#

yeah its all plugged

lime rapids
#

that includes the connector sometimes the cabels are not correct in there

#

for fun unplugg and replug it

simple maple
#

ye still trying to meet god

#

when i find my old z wire for my e3 ill try htat

lime rapids
#

hmm

#

cable could be otherwise if you replaced everything maybe try an old firmware of reset the epprom

#

It really sounds like the phase is inverted to me

#

There are a few situations where the wire for a motor can get plugged in upside down somewhere, and it does this

#

If you invert the two pairs (red and blue, green and black) it will turn the opposite direction

#

It's unfortunately kinda common for 3rd party NEMA stepper motor cables to have the pins scrambled, and have to be taken out of the connector and switched around like this

lime rapids
#

But would that make it happen suddenly?

kindred grove
#

Suddenly?

#

It's trying to do the normal homing operation just in the wrong direction isn't it?

lime rapids
#

yes but suddenly not always

simple maple
#

Yall got firmware recommendations incase it might be a firmware issue?

kindred grove
#

My self compiled Marlin has been fantastic once I got over the immense migraine of setting it up

simple maple
#

Ok i tried another wire and surprise surprise it still wants to go to god

simple maple
#

Also just realized when it moves up it still reads as 0.00

kindred grove
#

Doesn't start counting until it reaches the homing switch

simple maple
simple maple
#

i need to try and figure this out as soon as possible

#

Have you changed any hardware or is it only the firmware that you have updated?

simple maple
gaunt furnace
#

What hardware have you changed

simple maple
#

the actual stop and wire

gaunt furnace
#

Is that since you have had the problem

#

Or an attempt at fixing

simple maple
#

yup

gaunt furnace
#

So you Z is reversed?

simple maple
#

ye

gaunt furnace
#

Can you get a pic of the steps per mm from the configure menu

#

To be clear, it was OK b4 you flashed new fw?

simple maple
simple maple
gaunt furnace
#

In the printer menu the is a screen showing how many steps per mm travel, I think it usually says 800 for x, y

simple maple
#

Where

gaunt furnace
#

Depends on printer and fw

#

Marlin 1 and 2 are different and some Enders display this differently as well
