This might help.

When set to ohms (orange on the left side, infact the symbol below the 600 may be intended specifically for continuity the arrow and the beep symbol), you can touch the two probe tips together and the display number should change, and maybe beep. Meaning there is a connection between them. Touch something metal and it should do the same. Touch two ends of a wire, same thing.

It will probably be easiest to remove the endstop from the printer entirely so that you can check the wire more easily. You'd basically want to touch one of the wires at the end that plugs into the printer, and the other end at the endstop itself.

@Phaedrux

Yeahhh .. . so i think its the actual endstop. Its really wiggly. . i don't think its suppose to be this way . . i just ordered some new ones, and new cables to dead this whole issue. by the time i'm done ill probably have enough supplies for another printer.

[gabrealek]

@Phaedrux BUT THANK YOU THOUGH!! NOW I KNOW HOW TO USE IT THE RIGHT WAY.

[Phaedrux]

Hmm, yeah wiggly isn't great.

There is a way to get up and running without a Z endstop at all though. You can configure it to ask you to jog the print head down so that the nozzle touches the bed to set the Z height. Manual probing.

You'd need to change your config.g

M558 P0 H5 F300 T6000
G31 x0 y0 z0 P500

And then in homeall and homez where it says

G1 H1 Z-405 F3000 ; move Z down until the endstop is triggered
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)

replace that with

G1 X150 Y150 F6000
G30

Then when you try and home it will do xy, move to the center(ish) and there will be a pop up asking you to move Z jog it down carefully and when the nozzle is just touching the bed, hit OK.

Pretty handy in cases like this. I used this the other week when I broke a BLTouch pin.

Haha, good luck with your first print.

[gabrealek]

@Phaedrux
I am SO SCARED. . lol thanks for the luck . . I NEED ITTTT

[gabrealek]

@Phaedrux okay so do is erase something out of my config? or rather where do i put this into the config

Okay i think i see . .

; Z-Probe
M558 P0 H18 F120 T480000 ; disable Z probe but set dive height, probe speed and travel speed
M557 X10:220 Y10:220 S20 ; define mesh grid

replace with

M558 P0 H5 F300 T6000
G31 x0 y0 z0 P500

[Phaedrux]

Replace with:

M558 P0 H5 F300 T6000

[gabrealek]

@Phaedrux

G91
G1 H1 Z-400 F3000
G92 Z0 ; change Z0 to match the actual Z co-ordinate at which the Z end stop triggers
G1 Z10
G1 H1 X-300 Y-300
G1 X5 Y5
G1 H1 X-6 Y-6 F300
G90

change to

G91
G1 X150 Y150 F6000
G30
Do i leave everything under this there or void?
G1 Z10
G1 H1 X-300 Y-300
G1 X5 Y5
G1 H1 X-6 Y-6 F300
G90

[Phaedrux]

For homeall try this

G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-300 Y-300 F3000 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 X5 Y5 F6000 ; go back a few mm
G1 H1 X-300 Y-300 F3600 ; move slowly to X and Y axis endstops once more (second pass)
G90 ; absolute positioning
G1 X150 Y150 F6000 ; move to center
G30 ; probe the bed
G1 X10 Y10 Z10 ; move to parking position

[gabrealek]

@Phaedrux YESSS !! it worked perfectly!!

[gabrealek]

@Phaedrux Hello again. Ive been trying to fix this issue all day to no avail. After i home my printer and start the print it does not go down to the bed. its about 2mm above and it doesn't print. Ive checked the settings in cura and i cant figure out where its going left. . . Ill post the first few lines. THANKS for helping me once again.

Did you change your G31 command in the config.g to have Z0?

yes

now you need to calibrate the trigger height of the probe

[gabrealek]

@Veti ok thank you . ill do it after my errand and keep you all posted

No probe involved in this case. Just manual probing due to a broken Z endstop.

[gabrealek]

@Phaedrux yes, I figured after trying to follow along with it. It’s working for the most part now though. I’m having some mechanical issues at this point. My feeding gears were all off and I releveled the bed. I’m about to try a print now. Thank you all for the consistent help.
