Pogo Pins that connect the probe or drill to the V-One

@TSS_Bill Pogo Pins that connect the probe or drill to the V-One.

My V-One recently has not been able to determine if the probe is attached. It was working fine.

Looking at the pogo pins they don’t look the same. One seems very loose and the other two seem stiff. Is this normal and my probe connection problem is a different issue or is this the problem?

If this is the problem is there an easy solution?

[Rocksetta]

no worries I solved it the 2 stiff pins just needed a bit of probing with the probe to loosen them up

[TSS_Bill]

Excellent. The pins can sometimes use a little encouragement moving. Give them a gentle push and see if they pop back out. If the pins continue to be problematic, please send a message to support@voltera.io.

My 3D Printer occasionally needs some sewing oil. Is that a really bad idea to oil the contacts.

[Rocksetta]

Any opinion @TSS_Bill or anyone else about a miniscule amount of oil on the Pogo pins?

I don’t think it would hurt, but perhaps hold off and see if the problem comes back. I’ve never had that issue with mine, it could be that Voltera changed the component they are using and your feedback may help in identifying a more generic problem, or perhaps it is something specific to your environment or build.

The main problem I’ve had is with the Z-limit switch, it seems to collect rubbish (small lumps of dried paste, etc) which drop into the bowl and cause it to stick, often requiring some serious jiggling to get it to work consistently.

@cborn and @TSS_Bill

I just purchased a 2-3 year old used V-One ($3500 CDN), so I am a beginner but the V-One might have had situations that I don’t know about. The PoGo pins are getting stuck every 2-3 times I connect the probe, so it is an ongoing problem. I will try a micro amount of thin “sewing machine” oil.

Yes, I also have a bit of rubbish in the z-limit switch. I wonder if anyone has a good cleaning idea. I don’t really want to take the V-One apart. However if anyone has instructions on how to do that, it would be fun. I teach High School Robotics so there is a slim chance that I would be able to put it back together again.

It isn’t difficult to take apart.
Here’s the Z-Min replacement guide they sent me with a replacement switch.
(It may be available online in the Support pages, but I didn’t find it with a quick search)

Unfortunately the PCB layout had changed between my Kickstarter version and the one current when they sent the switch so it didn’t fit, but the disassembly instructions shoud work.

@cborn I love that. Just knowing that 4 screws gets you to this is great.

Can anyone take that picture and put labels on it? I see 2 steppers, the limit switch, power switch, most likely the power supply. Cute row of LED’s.

Or improve this image. Not really sure which stepper does what direction.
