V-One disconnects and drill stops moving

[jazozaya]

Hi everybody,

It has come to our attention that a small set of units shipped out in 2016 are having issues with the new V-One Drill attachment.

From the symptoms described, it appears the drill attachment is generating quite a bit of static electricity during operation and then discharging it into the V-One, causing USB communications to stop. If this happens, the software will remain responsive but you cannot send commands to the printer until you physically reconnect the USB cable and establish a new connection.

This only affects units made in 2016, since they do not have the same level of ESD protection as the newer printers. The engineering team is working on a fix and hope to roll it out ASAP.

If you have encountered this issue, please let us know by submitting a support package through the app (clicking the envelope in the top right corner).

Thank you

Hi everybody,

Good news - We have found a simple & easy solution to this disconnect problem.

Bad news - The solution requires some hardware, so we cannot fix this with a software update.

If you are experiencing this issue please submit a support package through the app with V-One Drill Disconnect as the problem description and we’ll send you the required part ASAP.

Regards,

Hi Jesus,

Is the hardware fix something that could also help with the occasional USB comms problems we get when heating, which used to be a lot worse with the noise from heater using PWM in the control loop, or is it specific to the drill?

Hey,

It’s not specific to the drill - tough to say if it would 100% fix it but I think it would help.

We were never able to reliably reproduce that disconnect issue during heating in our office. However in early 2017 we made some design changes that made the machine more resistance to static discharges and power surges. Random USB disconnects went away after that.

Do you still encounter the heater disconnect issue regularly?

Do you still encounter the heater disconnect issue regularly?

The change from PWM to on/off heater control made a huge difference, but the problem is still there. I wouldn’t say regularly, just occasionally.
I had some problems with the Beta drill, for example going from full speed to stop in one step would cause disconnect/lockup, but that may have been another issue with the Beta?
I can’t say about the release version drill, I got notification from Voltera that it had shipped 3 days ago, but clicking on tracking goes to Canada Post, which says it hasn’t been received yet!
If it is still sitting there and you have an external fix, perhaps you could add it to the box?

Following up on the release drill, it just arrived this afternoon (4:20pm), although Canada Post still denies it exists.

I must say you guys have done a fantastic job with it, so professional!
A great little multi-language manual too. Although - no Portuguese?
I see you’ve tidied up the grub screws, only one now which is good, I was always going to the wrong one.
There seems to be more slip between the motor and chuck when turning by hand than with the beta. It seems a very rubbery connection?
More when I fully un-box and give it a run.

Many thanks, and congratulations!
