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.
-
@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?
-
Yes, still remove the H2. Glad that
!took care of the homing. -
@Phaedrux i took off the H2 and it wouldnt let me home all it gave me
G28
Error: G0/G1: insufficient axes homedI put it back on and homed all again and it homed correctly . . . idk whats going on.
-
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.

Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: at min stop -
@Phaedrux
yes. Z is still triggered .
-
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". .
-
@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 homedDoes this mean i have to home them all individually at this point?

would this work? -

Nope, just the one for the XY axis move.

@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.

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

G90 ; absolute positioningThe 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.

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)
-
@Phaedrux Okay.
With both of them my z wont go any lower than the middle. i cant get close to the bed at all . . -
If you send just
G1 H1 Z-400 F600in the console does it move the z axis down to the endstop or does it just sit there and change the z axis position to 0? -
@Phaedrux said in New to the duet COMPLETE NEWBIE:
G1 H1 Z-400 F600
It just sits there. when i press home z it goes higher. when i try to bring it back down it does nothing.
