Hypercube Piezo Orion - I dont understand...
-
So, I have had this Duet WIFI working outstandingly in another printer while it printed parts for its Hypercube replacement. I have this thing all assembled and am working toward making this Hypercube operate even more outstanding than its predecessor. If it were not for my simplistic understanding of the config...
X and Y endstops work great. I have a similar one for low Z that the board acknowledges (lights the LED on the board) but does not stop downward motion.
also, when homing X or Y the bed raises 3~ inches - the board finds its X or Y and then drops again.
When homing Z the bed raises a few inches (no where near the nozzle/piezo and then presents me with this;
Not sure why this happens, should not the probe define its location? I have read and tried a number of examples like these ones;

What do you have in homeall?
The manual bed probing is presented when you have M558 P0, but your config shows P1 which I think is for analogue probes.
I'm not sure, but I thought the Pieozo Orion was supposed to use P8. What does the Piezo documentation say?
-
Homeall shown below;
In that last link i posted (from Piezo) it shows using P1, although the other examples show using 5 and 8 of which I tried as well.; homeall.g

What do you have in homez?
@soreloser said in Hypercube Piezo Orion - I dont understand...:
G1 X15 Y15 F6000 ; go to first bed probe point and home Z
G30 ; home Z by probing the bedYou should probably change the G1 position to move the nozzle to the center of the bed.
I believe P8 would be the right probe type to use.
After you change it and reboot send M558 in the gcode console by itself to see what the firmware thinks you have configured.
Then you can use these steps to try and test your probe safely

M558
Error: Z probe 0 not found -
Which version of RRF?
Which version of the Orion? Does it have the two rows of pins, one for analog and one for digital or just one row for digital? If you're connected to the digital pins on the Orion, you should use P8 for M558. If the analog pins, use P1. Also if analog, use I0.You have M574 Z0 and that needs to be Z1.

Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.0 (2020-01-03b3)
Its the newer version of the sensor, i have tried both sets of pins, right now using P8 on the M558. I will change the M574 to Z1 and see. thanks! -
Same;
i rechecked the wire connectivity and that it is properly oriented in the z probe port of the duet, all good (oh ya, and its wired to the digital part portion of the Piezo).
I turned down the sensitivity to see if it might be triggered prematurely, same. When i send the M558 code i receive 'Z probe 0 not found' , what should it be returning? -
Can you post your m558 command as it is now?

M574 X1 Y1 Z1 S0
M558 P8 I1 R0.4 F300 X0 Y0 Z0 -
Should i see some reference to the sensor in the status panel of GUI?

You are missing a few parameters like the dive height, travel speed. X0 Y0 Z0 is no longer used, so remove those. Also in RRF3 the inversion is done in the pin definition and not the M558, so remove the I1.
Try this
M558 P8 H5 F300 T6000 R0.4 C"!zprobe.in"C"!zprobe.in"` this must reflect the pin you're actually connect to. Are you using the Z endstop pin or the z probe pin? How are you wired?
Delete your
M574 X1 Y1 Z1 S0and use the RRF3 syntax:M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystopYou don't need a definition for Z here since you're using a probe.
I think this should get you going with RRF3.
-
Once you get to the point of seeing the probe, I'd actually use it in analog mode because you don't have to fiddle with that tiny pot. When it's connected properly, you should see a constant reading of about 525-575 and touching the nozzle should cause the reading to jump then come back again. It happens too fast for the web console to keep up sometimes though. You can then set your G31 trigger threshold to around 10 + whatever the stable reading is. Of course, test that it stops the Z movement with your finger before you let Z home on its own.

@Phaedrux
I am using the z probe input. Thank you, I will try your suggestions when i am in front of the machine tomorrow -
@gtj0 Ok, cool - makes sense!
-
@Phaedrux WOW! Awesome! it works. Thank you for your assistance, I learned a lot. I have much more to do but this portion now works. My configuration portion looks like this;
; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop '; Z-Probe
M558 P8 H5 F300 T6000 R0.4 C"!zprobe.in" ;DIGITAL mode, NO/NC, delay, speed, used as axis endstop
G31 X0 Y0 Z-0.1 P600 ;X, Y, Z offsets, sensitivity/thresholdFor now it stays digital until final tuning and try analog, thank you everyone.
