Don't feel too bad, 3D printing is probably one of the most complicated hobbies you can pick up.

[gabrealek]

@Phaedrux Okay. . so it tried to print again . . but . the extruder isnt going up or down . .

M574 Z1 S1 P"!zstop" ; configure active-high endstop for low end on Z via pin !zstop

Is your Z endstop the same as the other endstops? Your config has it as inverted signal, which could cause it to act as triggered even when it's not, meaning your homing is off.

Does homeall work to move all axis to their endstops correctly? Are you then able to jog all axis around correctly?

-x to the left, +x to the right, -y moves head to front of bed, +y moves head back, -z moves nozzle towards bed, +z moves nozzle away from bed.

[gabrealek]

@Phaedrux im not able to move to any - axis. I was able to this morning and i havent unplugged anything. Should i go into my config and change that?

@gabrealek said in New to the duet COMPLETE NEWBIE:

G1 H2 X5 Y5 F480000 ; go back a few mm

In your homeall can you change this line from G1 H2 to remove the H2 completely?

What does it do when you tell it to home all?
Does it move towards the endstops?

I'm not sure what you mean by not able to move to any - axis.

[gabrealek]

@Phaedrux whew . . Uhm so i went and took the "!" from in front of the zstop

M574 Z1 S1 P"zstop" ; configure active-high endstop for low end on Z via pin zstop

and now i'm able to move everything accordingly. It wouldn't let me use any of the negative machine movements. I dont know why it inverted it like that. . Do you think i should still go and remove the H2?

[Phaedrux]

Yes, still remove the H2. Glad that ! took care of the homing.

[gabrealek]

@Phaedrux i took off the H2 and it wouldnt let me home all it gave me

G28
Error: G0/G1: insufficient axes homed

I put it back on and homed all again and it homed correctly . . . idk whats going on.

[Phaedrux]

That's kind of why H2 shouldn't be in there. H2 will let it proceed even if there is a problem.

Looking at the printer from the front (so that the bed motor is at the rear) the 0,0 origin point should be the front left of the bed. -x should move to the left etc as I mentioned above.

We can test this without trying to home the printer first. Turn off the printer, move the print head and bed to the center point. Now turn the printer on and send g92 x150 y150 z1. Now you should be able to jog the axis around with the buttons to test that they move in the correct directions.

Then we need to know where the endetops are physically located on the cr10. IF it matches the ender3 the x should be on the left and y at the back by the motor. Is that right?

Then send m119 to get the status of the endstops. They should all say not triggered. And when you press them and send m119 it should say triggered.

@Phaedrux
yes. Z is still triggered .

[gabrealek]

@gabrealek

Endstops - X: not stopped, Y: at min stop, Z: at min stop, Z probe: at min stop

Y is triggered but Z is not at the moment and it still reads as "triggered". .

[gabrealek]

@Phaedrux They are all moving correctly . im about to move it to the center to see if its still triggered. .

Error: G0/G1: insufficient axes homed

Does this mean i have to home them all individually at this point?

G1 (H1) Z18 F480000 ; lift Z relative to current position
would this work?

[Phaedrux]

@gabrealek said in New to the duet COMPLETE NEWBIE:

So just the first H2 right?

Nope, just the one for the XY axis move. G1 H2 X5 Y5 F480000 ; go back a few mm

[gabrealek]

@Phaedrux So do i change the value for F480000?
As in go back a few MM i took it down to

G91 ; relative positioning
G1 Z18 F480000 ; 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 H2 X5 Y5 F480000 ; go back a few mm
G1 H1 X-300 Y-300 F3600 ; move slowly to X and Y axis endstops once more (second pass)
G1 H1 Z-400 F3600 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)

So now when i try to homeall i cannot, it gives me

G28
Error: G0/G1: insufficient axes homed

So now its

G91 ; relative positioning
G1 Z18 F480000 ; 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 F480000 ; go back a few mm
G1 H1 X-300 Y-300 F3600 ; move slowly to X and Y axis endstops once more (second pass)
G1 H1 Z-400 F3600 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)

@gabrealek said in New to the duet COMPLETE NEWBIE:

I think this should work. Since you have a Z end stop you can start by homing Z.

My printers don't allow for homing X and Y at the same time - so I don't even know if it is possible. If not just do them one axis at a time.

Add/Adjust F params as desired.

JOOC where did the 480,000 value come from? That is rather fast.

 G1 H1 Z-400 F3000
 G92 Z0 ; change Z0 to match the actual Z co-ordinate at which the Z end stop triggers

@fcwilt they were generated with the config tool . . what should it be set to?

The reason for the error is because you've taken the H2 off of the Z move at the start and end. Those were ok. I just wanted you to remove it from the XY move in the middle.

This would work, but @fcwilt provided a better option anyway that homes the Z axis first.

G91 ; relative positioning
G1 H2 Z18 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 H1 Z-400 F3600 ; move Z down stopping at the endstop
G1 Z5 ; back off
G1 H1 Z-400 F600 ; home z again slowly
G90 ; absolute positioning

F480000 is 8000mm/s which is really fast. But it wouldn't actually be able to use that speed because the max speed limit set in config.g is 6000mm/min which is a good cruising around speed (100mm/s)
