Tips for adjusting Precision Piezo Orion

M574 X1 Y1 Z0 S0

Das something to setup, what style is your printer?

You need to Home first X and Y and last Z.

In the beginning dont use G28 only,

Use G28 X
Then G28 Y
Then G28 Z

Before you do, tell the printer style and where are the Endstops

[cabal2000]

@hevilp
Core XY.

G28 Z
Error: G0/G1: insufficient axes homed

[hevilp]

Okay:

; Endstops
M574 X1 Y1 S1 ; Set active high endstops
M574 Z1 S2 ; Define Z to use Probe. Home to Min

; Z Probe
M558 P8 I1 R0.6 F300 Z1

@hevilp
Nope!!
I only have it connected to the z-stop switch. This is correct right?
And also, which is the correct one i should clicked on Switch/Unmodulated/simple Ultrasonic etc...?

[hevilp]

No it comes to the z Probe connection, not the end stop z

Take a look at the wiring guide from duet for your Board

[cabal2000]

@hevilp
Will that makes more sense!! OK, 5v or 3.3v and Z-Probe_mod I am guessing!!

[hevilp]

I dont know your Board, but piezo can do 5v yes

[cabal2000]

@hevilp
I think I have that figured out BUT for some reason the z is not going up.

[Moriquendi]

I'm do not know the Maestro but...

To use the Orion as the Z-endstop and the Z-probe it must be connected to the Z-probe connector. As @hevilp says, your M558 should be...

M558 P8 (mode 8, digital, unfiltered) I1 (inverted, active low) R0.6 (wait 0.6s before Z-probe) F300 (probe at 5mm/s) Z1 (probe from 1mm z-height)

M558 P8 I1 R0.6 F300 Z1

Did you use the Duet online configurator?

I'm on holiday at the moment so I don't have access to my printer to check your config against mine.

@moriquendi So, do I just change the one line or take everything out I just add this line. Sorry for such noobs questions, very very new to Duet boards. And yes i did use the Duet online configurator. I used the "Switch" setting. And set all the endstops to Low End. Z to Z-Probe.

[Moriquendi]

@cabal2000 Just change that line in your config.g

Here's the relevant part of my config.g

; Endstops
M574 X1 Y1 S0 ; Set active low endstops

; Z-Probe
M574 Z1 S2 ; Set endstops controlled by probe
M558 P8 I1 H2 R0.5 F300 T6000 ; Set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height

The important parts are:

M574 X1 Y1 S0 ; X and Y endstops active low.

M574 Z1 S2 ; Z-endstop active low, controlled by Z-probe.

Do you have these lines in your config.g?

@moriquendi
What do you have in your homez?

[cabal2000]

This is what I have:

; homez.g
; called to home the Z axis
;
; generated by RepRapFirmware Configuration Tool on Mon Sep 17 2018 22:03:45 GMT-0230 (Newfoundland Daylight Time)
G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G90 ; absolute positioning
G1 X150 Y150 F6000 ; go to first probe point
G30 ; home Z by probing the bed

; Uncomment the following lines to lift Z after probing
;G91 ; relative positioning
;G1 S2 Z5 F100 ; lift Z relative to current position
;G90 ; absolute positioning

The head moves to x150 y 150 (center of bed) but when the z starts to rise the head is slowly moving to the left. It isn't staying on center

Perhaps you have axis skew compensation enabled in config.g? It's the M556 command. Not to be confused with M558, which configured the Z probe.

[Moriquendi]

My homez.g is the same as yours except for different dimensions.
