You need to have pullups enabled for the pin that SIG is connected to. The SIG pin on the pcb only pulls the pin to 0v, it cannot drive it to a higher voltage. This also means that if you dont have the SIG pin plugged into a controller board (Ramps etc) it will always read 0v. Idrisby Moriquendi - General
Yes, that is the normal function of the LEDs. Idrisby Moriquendi - General
Ahh, of course... For me, homing Z means using the probe, for you on a delta it doesn't. In which case you only use the speed reduction code around the parts of the files that use G30. Idrisby Moriquendi - General
Yes, essentially my home.g files look like this; ; Reduce Z jerk and acceleration M201 Z5 M566 Z0 //////// Probe stuff/////// ;Reset Z jerk and acceleration M201 Z50 M566 Z5 As I understand it, the home.g files are macros. Isn't the function of G28 to call homeall/homedelta? What does the homedelta.g file look like? Could it be changed to do this? Move up to hit top endstops: Move down 790mby Moriquendi - General
That would make it very slow on a large delta. I have not used the Duet on a delta so this is from a cartesian viewpoint. I've put code into all my home.g files that decreases acceleration and jerk before probing and increases again after, perhaps you could do the same for Z-speed? You could also put in code so that before probing it always homes to the top (Z-max?) and then moves down 790mm befoby Moriquendi - General
I don't have a drawing for the Orion at the moment. The hole is currently 6mm, I know it can be enlarged to 6.5mm but anything more that that and I think you'll cut the traces between the piezos. Idrisby Moriquendi - General
The piezo element responds only to changes in pressure, it automatically adjusts to the weight of the bed. The tuning is only required to achieve minimum probing pressure while avoiding false triggers due to vibration. You may find the accuracy and repeatability are improved by having the bed positively fastened down rather than just resting there, particularly when probing outside of the triangby Moriquendi - General
@p40whk; Sorry to see that, can you PM me your order number and I'll send you a replacement. I'm assuming you were printing at the time? The nozzle probably hit the print, there's quite a long lever between the nozzle and the mount so it can apply quite a lot of force. @Wescherry; It's to allow for the larger bowden tubes of 3mm filament. Also, adding material near the centre of the cylinder doeby Moriquendi - General
Very strange... Rather than messing about with trying to work out what's going wrong, I'll send you a replacement, would you be able to return the board you have to me? Idrisby Moriquendi - General
What are the LEDs doing? Idrisby Moriquendi - General
I recommend using mode 8 (P8) in place of P1, the output of the board is digital. The voltage at the SIG pin when untriggered (red LED lit) should be the same as V+, in this case 3.3v. When the board is triggered (blue LED lit) the voltage on the SIG pin should be 0v so something, somewhere, is going wrong. Are you able to measure the voltage of the pin on the Duet where the SIG pin would conneby Moriquendi - General
Hi Alex, Sorry I've been slow to reply to your email, life is very busy at the moment. What kind of controller board are you using? Do you have pullups enabled? Are you able to measure the voltage of the SIG pin when the Uni board is plugged into your controller? Idrisby Moriquendi - General
That's probably the answer and it is at least a fairly cheap place to start. Idrisby Moriquendi - General
I believe so yes though I've not used a BMG, you might need to adjust the length of PTFE that protrudes slightly. Idrisby Moriquendi - General
You poor man, what a terrible situation to find yourself in... I tried using the probe on x10 but I still found that it caused issues with triggering. Specifically I'm trying to look at the signal generated by the Orion during actual probing on an active printer. It's possible that I was seeing not just loading issues but also injecting noise by extending soldering long wires to the piezo disks.by Moriquendi - General
@ Holmes4, You should be able to loosen the four assembly screws half a turn without any wobble issues, the mount is designed to preload the PCB which will keep the nozzle solid. On the other hand, if loosening the screws half a turn does cause the nozzle to become loose then it's likely you didn't have the screws tight enough in the first place, there shouldn't be any gap between the top piece,by Moriquendi - General
Yes, it's this one. Idrisby Moriquendi - General
Yup, I've been meaning to for a while. Unfortunately, E3D won't do a wholesale price for me so I'll have to charge a small premium over the E3D price to cover my costs but it shouldn't be much and should be covered by the savings in shipping. I've considered stocking the threaded V6 heatsink to go with the new Orion Threaded heatsink mount, anybody interested in that? Idrisby Moriquendi - General
4mm OD tube? That shouldn't be a problem, there should be clearance for up to a 7mm hole if you're careful however, I don't know how much strength would remain if you were to remove that amount of material. Idrisby Moriquendi - General
It works very well, typically you wont heat the nozzle to full print temp to avoid oozing, I'd suggest 120-160c and at those temps I've not seen any issues with PEI. Idrisby Moriquendi - General
@Pyroball, It looks very interesting, can you give an explanation of how it works? Specifically how the software and hardware interact? Idrisby Moriquendi - General
That beta mount is not one I've had any experience with, looking at it I think it might work better on a machine with a bed that moves in Z rather than the gantry. You have a couple of options if you want to keep the Titan Aero with piezo sensing. You could engineer your own mount that reduces the amount of cantilevered mass or you could try underbed sensing which is ideally suited to beds thatby Moriquendi - General
Delay before probing should be more like 500ms, other than that it looks good. Idrisby Moriquendi - General
@p40whk: The I1 makes the Duet invert the logic of the input, 0v becomes triggered 5v becomes untriggered. @iamthebest22: You need to enable pullups for that pin, the Orion board has an open collector output meaning it can pull the SIG pin to ground but it doesn't raise the voltage itself. Idrisby Moriquendi - General
You need an I1 in here, the output of the board is active low, 0v = triggered M558 P8 I1 R0.4 H5 F500 T6000 ; Set Z probe type to effector and the dive height + speeds I'd suggest changing the other values as well as indicated. Idrisby Moriquendi - General
Can you measure with a multimeter the voltage of the pin on the controller board (FYSETC) that the sig wire connects to? Both with the wire plugged in and with nothing plugged in. Which version of the Orion PCB do you have? The version number is at the opposite end of the board to the connections. Idrisby Moriquendi - General
There's a bit of confusion going on I think; The older boards, the Piezo20 and older versions of the Universal and Orion drove the SIG pin directly from the opamp output. This is simple but has a couple of issues, namely that because the output of the opamp is also driving the LED there's a limit to how low the opamp can pull the SIG pin. The latest versions of the Universal PCB use an open colby Moriquendi - General
Quoteruggb I suspect you have an open collector output that turns on (shorts) when active. Any resistor 10K or higher to a + voltage (whatever is supplying the board) will allow you to see a voltage change. The problem is it isn't latching and is a short duration (useconds) so you probably won't notice it on a meter. You need a scope. This is correct, you need a >10k resistor to V+ to pull upby Moriquendi - General
If you don't have anything connected to the signal line there's nothing to pull the signal line up to 5v so you wouldn't see any signal. You either need to connect a 100k resistor between the signal line and 5v or plug it into a controller board with pullups enabled. Idrisby Moriquendi - General
The signal line is active low and requires pullups to be enabled. You should see 5v and the red LED when untriggered and ~0v and the blue LED when untriggered. Idrisby Moriquendi - General
