Tips for adjusting Precision Piezo Orion
-
Hi,
I am trying to setup Precision Piezo Onion (PPO) in a Duet 2 board... But i am having issues with fine tuning.
Things that DO work:
-
Duet decides the PPO correctly, I have tried to configure it as digital or analog. Both work. What do you recommend?
-
PPO, detects when something touches the Nozzle, I approach an object to it in an energetic way.
Things that DO NOT work:
-
PPO (this is mounted on a Duet Board), the calibration begins, and some points it does well, after touching the bed gently, it detects it and goes to the next point. But other points, it seems that it does not do us so well, the touch with the bed is much more "strong", even though it seems that the calibration manages to finish it.
-
The problems come when I try to do the "BED COMPENSATION" in which you have to take the height of many points. Some points take them well, others the touch is stronger, and at a given time, after about 20 points, stops taking.
I have watched videos of YOUTUBE, and it seems that PPO should have a screw to adjust the sensitivity, but the installed one does not take it, and the one that I am going to send you, that I did not think about opening it, but I have opened it to see if it had the screw, it does not wear either. So, what ... How do I adjust the sensitivity without this screw?

PS: it's "Orion" not "Onion"(which translates to "cebolla" in spanish)

have you looked at this.

there is a potmeter for adjusting sensitivity..However I never touched it and I use digital.The touch is very gentle. What is you configuration.maybe reduce the speed at which it decends -
Seems I got the same problem

Me too!...…………………..

Can you please describe the problem you are having?

Please watch my other thread.
I described it there. If you need more Informations, please ask me.

Hi guys.
Just installed my Duet Maestro. I was Ramps before this and truly not 100% sure on what I am doing. Little bit of a learning curve so to say.
What did you guys select when you were defining the Orion? Switch/Unmodulated/simple Ultrasonic etc...
And for the Endstop Configuration, Active high, active low, z-Probe??
Sorry for the noobs question but I am am a loss. -
@hevilp Can you please see my questions below. Thanks brother!!
-
Please take a look at the other thread, piezo reference. There is all you need.
You need
M558 P8 I1 R0.6 F300 Z1
Z1 is because Im using this as endstop.
Just do it with the command, its better to understand with the command instead over the
Gui. -

This is what I have at present.
; Endstops
M558 P1 I1 R1 F300 A3 X0 Y0 Z0
M574 X1 Y1 Z0 S0; Z-Probe
G31 X150 Y150 Z0 P100
M558 P8 I1 R0.6 F300 Z1I am guessing I have something configured wrong.

Try
This is what I have at present.
; Endstops
M574 X1 Y1 Z0 S0; Z-Probe
G31 Z0 P100
M558 P8 I1 R0.6 F300 Z1 -

M574 X1 Y1 Z0 S0
G28
Error: G0/G1: insufficient axes homed -
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 ZBefore you do, tell the printer style and where are the Endstops
-
@hevilp
Core XY.G28 Z
Error: G0/G1: insufficient axes homed -
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...? -
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
-
@hevilp
Will that makes more sense!! OK, 5v or 3.3v and Z-Probe_mod I am guessing!! -
I dont know your Board, but piezo can do 5v yes
