Does any one know if the two Neoden eBay accounts - 'neoden' and 'neodentech' are both legit> I think I have seen the 'neoden' account from before, but now there seems to be also a 'neodentech'...

Thanks

Does anyone have NeoDen's stated part placement accuracy? is it around 80 microns?

I have the X/Y positioning as 5 microns just don't see a placement figure. thanks

Hello Pete_flex,

Positioning resolution is not exactly what you need.

XY-repeatability +/-0,02mm

We place 0402 with the machine during demonstration. And show the result under the microscope.
0201 is also possible when fine tuning the placement and pickup height.

Regards,
Gerard

I am having the same problem, and that is a failure of the camera or the cable that connects to the camera. I am waiting for a camera replacement to be sent to me from China on the 9th.

The complicated thing is to access the camera to replace it, you have to remove all the feeders on that side, and move the rail that hides 3 screws.

Hello.

Yes, my Neoden4 is under warranty.
How can I get the camera and the cable?
Can you provide complete instructions or a video where I see exactly how to replace the camera? The document I have does not show it in detail, it only reaches the step of removing the 3 screws from the photo.

regards

Posting this here, hope it is allowed.

There is a Neoden 4 for sale here in Ottawa, Canada. I know the seller and have seen the machine. Basically new.

No financial interest, etc. etc. Just pointing this out in case somebody wants a machine that is already in North America.

I don't have a neoden but...

How about cleaning the dirty nozzle and adjusting the camera settings (contrast, brightness) contrast up / brightness down.

You need to remove all the dust from the picture for the optical recognition...

I suppose the Problem is the inner circle from nozzle. The intensity is similar as the component. Four additional TH LEDs at the correct angle should resolve the problem. For that component just one single led is probably enough but four for not influencing negatively other component recognitions.

Hello,
thank you for help. Additional side LED light solve it and vision recognized it correctly. We will try develop some extra light for this type of components.
Thank you,
Jan

We had this. The positioning of the cable meant that it would hit something every time it started up. Eventually, it cut through some of the conductors inside it.

I asked them for a replacement then realised what a massive pain it would be to swap it as it's connected to an internal USB. They said you could just plug it in to an external USB on the machine but instead I just soldered the broken wires back together and relocated the cable. It's never been any trouble since.

There was another annoying problem where the end stop photo sensor was misaligned and the x-axis used to crash into the end.

These two problem spoilt was is otherwise a really good and reliable little machine. Since I fixed them it's been great.
