Piezo Orion and Duet Network

I have a Piezo 20 on my cartesian and love it. I have just completed a large delta and I bought an Orion module for it. The first module failed and I returned it. Now with the new pcb my printer locks up. Does anybody have experience with the Orion on a Duet board? I am about to give up on the Orion.

I received your request for support via email and replied to it. Please try to keep support requests to one channel, it's difficult to keep track of what steps have or have not been tried when it's spread out over different locations.

I've copied my email response to you below.

When you say locks up, does it give you any message?

Your M558 line in the config should look something like this,

M558 P8 I1 H2 F300 R0.5 Txxxx

P8 = mode 8, digital, no filtering,

I1 = Invert signal, active low

F300 = Probe speed 300mm/min or 5mm/sec

R0.5 =delay 0.5sec between xy move and z probe.

Kep in mind the Orion has a different pinout to the endstop than the Piezo20.

Good point, earlier versions of the Piezo 20 (including yours cwaa) use a non-standard pinout that is different from the Orion and later boards that use the standard endstop pinout.

I am using the pins for the Duet z-probe and am not using the endstops as this is a delta.

What O Lampe is saying is that the pinout on the PP Orion is different from the pinout on the older Piezo20 boards, if you haven't changed the wires around when you upgraded to the Orion then you will have the Orion incorrectly connected.

I have the Orion working somewhat. With the settings shown below when I send G30 it moves very slowly from home (450mm) and eventually senses the bed and then moves up to 10mm. I have manually measured the 10mm and it is right on. How can I speed up the movement prior to probing? BUT, when I use auto configuration the effector crashes into the bed. So I am still doing something wrong. Any ideas?

Have you changed the feedrate from F250 to F2500 in your homedelta.g?

I am sorry but I don't understand how changing the speed in my homing file will effect probing. It's after the G30 command that it slowly drops the 455 mm and probes. Homing works great. Can you explain further?

Because the first thing the Bed.g file does is home all (G28) setting the travel speed to F250 (if you haven't changed it), it then probes the bed which means that it has to move the full height of your printer at F250 which is going to take a while.

What is your purpose in sending G30 after homing? If it's to get a more accurate Z=0 position, then I suggest you use e.g. G1 X0 Y0 Z5 F9000 followed by G30. You can put those two commands in a macro file to save typing them.

Thanks for the advice.

Did it solve your problem?

The effector still crashes into the bed on auto calibration, but G30 works independently. So still something wrong! I don't know if I have the firmware set up correctly or the Orion just doesn't work! I can't be the first one to use it with Duet.

You're not the first one to use it with a Duet, I and many others do. If it works with G30 then the Orion is working. Somewhere you still have a configuration issue, I'm thinking it may have something to do with the Z-99999 arguments in your bed.g file or possibly the M665 ...... H440 in the config.g. I'm not familiar with how the Duet deals with delta printers, how much physical travel do you have in Z?

i was having the same issue with a newly built delta with a smart effector, and what i ended up doing was changing the dive height in the M558 to something more conservative like 50 to 100 mm, and then changed it back to a shorter distance once the auto-calibration ran and the settings were saved.

Thanks to both of you for the suggestions. I have been ill and not printing anything. Will get back after I look into this some more.
