@Jhonno Please can you double check your wiring, you should be connected to the pins labelled D, the A pins are currently only usable with RepRapFirmware. The behaviour you're seeing on the A line is normal. The digital output requires a pull up resistor otherwise it will remain at 0v. Which LEDs are lit? Idrisby Moriquendi - General
@Jhonno Which version of the board do you have? Idrisby Moriquendi - General
The noise being discussed was the result of a defective switch mode regulator, not something you're likely to experience. You won't need to take any special precautions with the digital output of the Orion. Idrisby Moriquendi - General
This sounds more like a defective switching regulator than anything else. Is the 5v converter on the main board? Idrisby Moriquendi - General
No purpose other than for the attachment of fans, they should not be used to mount the unit. Idrisby Moriquendi - General
Do you mean on the screw top plate? Idrisby Moriquendi - General
Are you able to try another oscilloscope? Do you use fluorescent lighting? Idrisby Moriquendi - General
@Jamorrow, Which product are you having issues with? @Luigello, I think I responded to an email from you but in case that was someone else: I have a mount for the microswiss hotend here (https://www.thingiverse.com/thing:4258918) but I do not believe it will be compatible with the DD extruder. The Orion relies on being between the hotend and the rest of the mount and I do not believe there isby Moriquendi - General

The top two are the diodes, BAV99, the bottom two are the transistors BSS138. Idrisby Moriquendi - General
@Kami The Orion is not open source so the schematic is not made public. Two of the "transistors" are not transistors at all but diode arrays BAV99. The other Diode is an RB521S @janth If the emi is coupled to the Orion before the amplifier and comparator stage it could be causing the Orion to trigger but too quickly for the LED to light up or be noticed. Have a look at the output of the A sigby Moriquendi - General
@ Kami, The transistors are BSS138, which diode have you damaged? Idrisby Moriquendi - General
In that case it may be that the EMI is causing the Orion to trigger. Do the false triggers still happen if you tune the Orion to be slightly less sensitive? Idrisby Moriquendi - General
Looks like EMI to me, I expect you would see similar noise on any wire of similar length connected to a high impedance input. Is it causing false triggers? Idrisby Moriquendi - General
@KenZ I presume you're using the old Piezo20 design? Are you using a 20mm or 27mm piezo disk? You probably need to tighten the assembly screws to reduce wobble. @Janith What voltage are you reading on the sig line? Do you have pullups enabled? Please ensure that you have connected to the digital output and not the analog one. Idrisby Moriquendi - General
@Ken I've cancelled your order and issued a refund.by Moriquendi - General
@janth, Higher probing speeds don't really help, I probe at 2mm/s. The Orion is sensitive to any lack of rigidity in the carriage or mount, they must be as rigid as possible. Also, the design of the hotend mount is very critical, I suggest you look at the parts I have designed here and see whether they can be made to fir your printer. @KenZ, My genuine products are also available from Filastrby Moriquendi - General
@KenZ Where did you buy your board? I have never manufactured boards with green LEDs so all boards with green LEDs are counterfeit. @Janth, The digital output of the Orion 2 behaves exactly the same way as a normal, mechanical, endstop. Please check that you have the cable connected to the set of pins marked "D" I have not used Marlin for a number of years but I believe it has an option calleby Moriquendi - General
Hi Koka, Can you PM or email me your order number please. Sounds dumb but are you sure you have the wiring correct? If you connect the signal line from the CR10 to the V+ pin on the Orion it will not have the current to power the board and the voltage will drop, please can you verify that the you have the correct pins on the CR10. The signal pin will will read 5v when nothing is connected becauby Moriquendi - General
I haven't been able to find dimensions for the effector of that printer but the spacing of the holes on the screwmount top piece is 23mmx12.5mm. If you're currently using a groovemount hot end you could get the groove mount kit and fit it as you would your normal hotend. The Orion PCB is self contained, it does not require another PCB to operate. Everything you need is included if you order theby Moriquendi - General
You probably need to adjust the four assembly screws, if they're too tight they can show the behaviour you describe. Try loosening each screw by half a turn and re-tune, you may need to do this more than once. Idrisby Moriquendi - General
By filling in the hollow section you have made the bottom clamp too stiff. The compliance of the bottom part is vital to the correct functioning of the sensor. Idrisby Moriquendi - General
You should tighten the screws so that there is no gap between the PCB and the mount, this preloads the PCB. It's not easy to say exactly how tight the screws should be, too tight and the sensor will be unresponsive, too loose and you'll get false triggers. My advice is to tighten the screws so that there is no gap then probe the bed. If the probe doesn't trigger as soon as the nozzle touches thby Moriquendi - General
The digital output probably needs tuning using VR2. Unfortunately I don't have much current experience of Marlin so I can't help you with that. Idrisby Moriquendi - General
You can solder extension wires to the piezo disks cables, try to keep the total length short but you shouldn't have issues with lengths up to 300mm. I strongly suggest you secure the wires close to the piezo disk and ensure that there is no stress on the solder joints of the disk itself, they are quite delicate. The lengths do not need to be the same. You do not need to see any deflection of theby Moriquendi - General
I don't see any issues with that design, should work well. Idrisby Moriquendi - General
If it were simply a matter of fitting the parts as close together as possible then yes, it could be made smaller, but there are other factors at play here.by Moriquendi - General
It's inconsistent how ever you do it and a has a fairly high failure rate. More importantly, the piezo ceramic is lead based, it's inert and until you disturb it by drilling it. Drilling it produces dust which is toxic and I don't want to have to deal with it. I have alternatives to drilled disks for almost all applications, eg the Andromeda pcb. Idrisby Moriquendi - General
Demand for the Piezo20 reduced drastically with the introduction of the Orion, I do not wish to maintain stock of a product that does not sell well, not to mention updating it every time a new iteration arrives. The Piezo20 did not die prematurely, it was replaced by a superior product. The Universal PCB can support all the applications that the Piezo20 could, perhaps not as neatly but it can.by Moriquendi - General
I'm really not making any more of the Piezo20 boards, not unless you want to special order a large number. The Piezo20 PCB was designed for a single product using a technique that I can no-longer support, drilling holes in piezo disks. The Universal PCB does everything you need to run a system like the Piezo20 but is also easy to use for underbed sensing, unlike the Piezo20 PCB. The mounting holeby Moriquendi - General
