Z Probe connection

Craig · 22 Jul 2018, 17:12

@whosrdaddy I connected it to the Z probe pins. When I turn the printer on the probes led comes on. I have the sensitivity set at P600. When the probe is just sitting it reads 620-630. When I tap it, the reading goes to zero and then right back to 620.

@craig I have been in contact with Precision Piezo, and this was their reply. "Hi Craig, Unfortunately I don't have any experience of the duet so it's not easy to offer advice. What I can tell you is that the Orion behaves exactly like a standard microswitch except that for the Orion you need to turn pullups off. Simon runs a Duet and should be able to help you but he's travelling in Europe at the moment and so replies may be slower than normal. I'll do some reading into the operation of the Duet with the Orion probe and get back to you if I find anything I think might help. Idris

Craig, don't use P3, it is used for analog probe types, I have several printers (only cartesion) using P8 which gives the best results...
Did you setup M574 to use a probe for Z?
something like M574 Z1 S2

@whosrdaddy I have tried most of the Modes and I was just trying another variation. BUT, I don't use M574 and its for endstops. I am connected to the Z-Probe pins. ??

I have a Piezo on my cartesian and love it. It runs on a Smoothie Board. So I have to learn over again how to make it work with a different board.

This is what I am using for endstops: M574 X2 Y2 Z2 S1

yeah, I forgot you have a Delta
so the config is basically correct.
Can you confirm that If you set M558 P8 I1 (thats I from Isaac), and you tap the nozzle, you see 1000 as probe value in DWC?

Craig · 22 Jul 2018, 21:23

The code below shows 360 n open and 1000 on closed or at contact. P8 mode did not show anything or respond.

M558 P1 I1 R0.4 H300 F300 X0 Y0 Z0
G31 X0 Y0 Z-0.1 P1000 ;
M557 R155 S20

This setup gives P=0 and on a tap goes to 1000. With this setup when I press G30 I can't stop the effector from going down. If I let it go, it slows about 50 mm above the bed and then makes two random moves. It then moves to X0 Y0 and probes. Comes up makes two more random moves, then back to X0 Y0 and Z35 and stops. I don't understand all of the movement, but at the end, the location is accurate..

If P8 does not work then it means that you are running an older firmware.
P8 is essentially the same as P5 but unfiltered (so faster).
What firmware are you running (check settings page in DWC)?

Craig · 22 Jul 2018, 22:15

@whosrdaddy 1.19.2

whosrdaddy · 23 Jul 2018, 07:03

@craig Thats really old. This will work in 1.21...
