New to the duet COMPLETE NEWBIE

fcwilt

It's late here (11:30 EST) and I need to turn in. We can take this up tomorrow.

I'm working on my 6th, 7th and 8th printer.

Even so I still take it one step at a time.

Step one is always to get the WiFi working so I have access to the DWC where I can do the rest of the configuration.

Then I connect one piece of hardware at a time and verify that it is working as expected - that stepper motors turn, end stop switches work correctly, fans run, heaters heat, etc.

By doing that when something doesn't work I know exactly where I need to look for the problem.

@Phaedrux I inverted it and it went down so far it cracked the glass .

Ah nuts. Sorry about that.

I'm wondering if your Z endstop wiring is not correct.

Regardless of the ! being there or not, if it's electrically connected to the Duet it should report as stopped/not stopped and change state if the switch is actually clicked at the time when you send M119.

Can you post a photo of the endstop wiring at the board? The creality endstops should be wired to the 2 outside pins of the endstop connector.

gabrealek

@Phaedrux its okay. I can always get another . no worries.

Phaedrux

Ok, I can mostly see the endstops and they all look like they are connected correctly with the wires going to the outside pins, so that's a good start.

Now to make sure the wires are actually connected electrically.

Send M119 and see what the Z stop says.
Then hold down the Z switch and send M119 again while holding it clicked and see if the status changes.

@Phaedrux

Its being so mean

1/22/2021, 4:44:48 PM M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop
1/22/2021, 4:44:33 PM M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop

Phaedrux

So being clicked or not it's not registering? Just as a control, text the other endstops as well.

If that is the case that pressing the endstop isn't registering at all then there could be a break in the wire or poor connection. In which case reseating the z endstop plug on the board may help. If you have a multimeter you can check the wire for continuity and whether the endstop switch will complete or break a circuit.

@Phaedrux
Okay. So how would i test with a multimeter? As in where to on the Z? Im still new at using this multimeter , ill post a pic to know exactly which setting to set it to. Also which command do i sent to test only for Z? THANKKASSSS

Phaedrux

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
G31 x0 y0 z0 P500
M557 X10:220 Y10:220 S20 ; define mesh grid

@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

@Phaedrux YESSS !! it worked perfectly!!
