sorry apparently this post has been considered as spam :s i will respond asap

@jay_s_uk

you were right i was on +Xaxis not - (facepalm)

Thank you

Sorry the span bot doesnt like it being posted

@jay_s_uk

So i know what you are saying but am i changing the

M557 X60:260 Y30:245 S20

to

M557 X217:260 Y30:245 S20 ?

@fcwilt said in Z axis not homing:

M561 ; clear any bed transform

What would i put for the M557 if it wasnt using an S value? i only put an S value because it feels easier to understand if i know the distance

235

sooo close now

ive recalibrated the Z probe, and redefined both the bed size and mesh size.

I have just one last issue it still wont hit the last point on the bed and throws out an error before continuing the rest of the G32 code

G31 P500 X-43 Y10 Z3.79 ; set Z probe trigger value, offset and trigger height
M557 X60:260 Y30:245 S20 ; define mesh grid

i thought it may have been the S value but that doesnt seem to make sense as 20 goes into 260

any more ideas?

@prior123 the Z probe can go further im just really confused why it thinks it cant

@jay_s_uk this has helpe massively! thank you.

How can i work out the true measurements essentially ive defined it all no with

M208 X60 Y-10 Z0 S1 ; set axis minima
M208 X235 Y235 Z260 S0 ; set axis maxima

however im not trying to define the mesh coordinates and i am continuously getting this

Warning: Skipping grid point X=200.0, Y=180.0 because Z probe cannot reach it

@jay_s_uk probably X-60 and Y-10

But i just changed that in the homeall.g and it doesnt seem to be doing anything

@jay_s_uk so should i comment out that line then? sorry im pretty unknown when it comes to programming

@jay_s_uk

the homing error is fixed but the x and y positioning when homing the Z via home all isnt working

@jay_s_uk This has stopped the warning sign! thank you
