@ Moriquendi:

Hi, thanks a lot. Can you tell me with my numbers which one is for what 1-5??

Thanks.

The top two are the diodes, BAV99, the bottom two are the transistors BSS138.

i search for long time a mount for my ender 5 with Micro swiss Direct Drive and all metal hotend,is there anything for mount it on my system ?

thanks

I just got a new one after managing to break my old one. However the new one does seem to trigger at all times the blue light is always lit. Anyone got a clue whats going on? Its the same mounted to not mounted and the pot seems to do nothing.

@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 is room here.

Well, it’s not the Orion module that causes these issues. The noise is on all signals and supplies. It occurs every time 2.1 us (460 kHz). I completely detached the Orion module which did not change anything. Then I changed to a dc power supply from the laboratory which didn’t change anything either. Even if I keep the reset button of the controller board pressed, the noise is still there.
I changed a lot since the last successful run on this machine:
- updated the controller board from the tronxy chitu stuff to marlin
- changed from the contactless z stop switch to the Orion
- changed from a titan bowden drive to a remote drive

So I guess, the emi it not being caused by
- the power supply since swapping didn’t change anything
- the Orion module since detaching didn’t help and it’s on all signals on the controller board
- the firmware since it didn’t help to keep the microcontroller asleep by pressing the reset button
- any fan since it is still there even if no fan is running

Has anyone any idea?

Are you able to try another oscilloscope?

Do you use fluorescent lighting?

Well, I used a different oscilloscope than 5 weeks ago and both showed the same results. We got fluorescent tubes at work but the issue also occurred at home (only recognized the z stop issue, I don’t own an oscilloscope). I will try with lights turned off tomorrow.

I have found a signal that switches with every emi pulse that I see on the z stop. It’s the output of the dc dc step down converter (MP1584EN) that converts the 24 V of the power supply to the 5 V needed for the microcontroller. I guess that this signal itself is not causing the emi but rather the current that runs though the cables from the power supply to the controller board in that moment. However, I broke something while measuring: there is no 5 V being generated anymore. The 24 V supply still works and if I switch to USB-supply, the rest of the board still works as well. So I guess I shorted the step down converter or some part close to it.

Moriquendi, I am curious about the four hex nut shaped objects at the four corners of the Orion mount top plate .... do they serve a purpose in anything other than possibly a delta printer?

Thanks

Do you mean on the screw top plate?

No purpose other than for the attachment of fans, they should not be used to mount the unit.

Hello again.

I don't know how my printer worked before I switched to marlin and updated the hotend/z-stop. When the stepper motors are activated, there's 10 V (peak-peak) noise all over the place, also in the 5 V part of the control board. It does not come from the motor cables: Detaching them from the board does not make any difference. My guess is: switching the 24 V for the steppers creates noise on the 24 V part that causes even the 5 V part to have the same noise which then spreads everywhere. I don't know what else to do, so I used the situation and purchased a control board that hat silent steppers and does not need endstop switches.

This sounds more like a defective switching regulator than anything else. Is the 5v converter on the main board?

It was. As I said, I destroyed the regulator while measuring. I then added an external that could handle 5A but it was still the same.

The new control board arrived today but none of the connectors fits and the pin mapping is wrong so I ordered these. This printer totally pisses me off.

Just trying to assemble my Orion, and apparently there is enough blobbing on the inside of the springy bottom part that grabs the heatsink groove mount that it won't close all the way, so the holes won't line up for screwing on the top parts. Any better solution than 3D printing a tiny custom sanding block just the shape of an E3D groove mount?

Update: My silly sanding block did work, here's my Orion experience so far: To Orion and Beyond

All this talk of noise has me worried. I have to run a few feet of cable through cable chains to reach my smoothieboard. Should I use some sort of shielded cable (maybe a shielded USB cable and cut the ends off). Any minimum wire gauge recommended?
Re: Precision Piezo Z-probe Now available.

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.

Well it was the tronxy board in general. Swapping the power supply made it better but still faulty. Now I switched to a SKR mini E3 v2.0 and that works great (and no noise). The electrical part is ready now. However, I am still not up and running. The orion is dialed in so sensitive that it triggers when I move next to the table the printer stands on. But when I try to use the Orion, the bed moves into the hot end and beyond until it triggers. Also the Orion feels more sensitive to touches from the side than from below.

I guess my custom designed print head is not great. 1st the hollow ring ring in which the Orion can “bend” has a wider diameter than the parts that came with the module. And 2nd some screw wholes do not fit which makes it all too wobbly.

I’ll report back as soon as I had time to redraw and print the print head parts smiling smiley
